Special Issue Information

Dear Colleagues,

With the development of computational technology and the increasing demand for system behavior evaluation, numerical modeling has become a popular and powerful method in both academic research and engineering practice. When the project involves a complicated construction process, the geological stratigraphic distribution is complex, high uncertainties are embedded, or multi-scale analyses are required, numerical modeling in mechanical behavior and structural analysis is essential. However, numerical results significantly depend on the input model parameters, boundary conditions, initial assumptions, simulation tricks, etc., and theoretical researchers and in situ engineers may suspect the results to be a computational game. To help overcome the hurdles faced by the application of numerical modeling, this Special Issue will highlight recent value-added contributions to the state of the art and state of practice for numerical modeling. We seek high-quality research manuscripts addressing key numerical aspects, including the following topics:

  • Advanced simulation algorithms;
  • Innovative numerical simulation methods;
  • Multi-scale and multi-physics computational modeling;
  • Artificial intelligence-aided numerical simulation;
  • Building information modeling-aided numerical modeling;
  • Full-life cycle evaluation of infrastructure;
  • Coupling analysis in numeric;
  • Case study using numerical method (foundation pit, tunnel, slope, building, offshore structure, etc.).

The utilization of reinforcement cage underreamed anchor bolts is prevalent in the reinforcement of foundation pit engineering, but there are few studies on the reinforcement of soft rock slopes and the influence of its parameters on slope stability. This study combines laboratory tests to analyze the mechanical properties of reinforced and non-reinforced bolts with finite element analysis to model the anchorage support system in soft rock slopes. Key parameters affecting the stability of the slope, such as bolt diameter, expansion section diameter, and anchorage depth, were considered. The findings indicate that the inclusion of a reinforcement cage leads to a more rational distribution of mechanical properties, promoting even axial force distribution to the grouting medium. An increase in bolt diameter enhances slope stability, while the expansion section diameter has minimal impact when a strong bond exists between the grouting body and the rock mass. However, in the absence of such bonding, increasing the expansion section diameter significantly improves slope stability. Deeper anchorage also correlates with higher stability, though the rate of increase in safety factor slows as the anchorage depth approaches the critical slip plane. In conjunction with field application, the research outcomes can exert a certain directive impact on practical engineering and can be used as a reference for the design method of bolt support for soft rock slope Full article

Shear-keyed tooth joints (SKTJs) are commonly used in prefabricated buildings, including wind turbine foundations, to connect prestressed modules. Due to the significant loss of prestress in precast wind turbine foundations, slip failure is more likely to occur than shear failure. In this paper, a predictive model for SKTJs under small confining stress based on the ultimate limit state theory is proposed. The effects of the number of shear keyed teeth, reinforcement, and confining stress on the shear capacity of SKTJs are analyzed numerically. The incremental coefficient, i.e., the ratio of the shear strength increment to the product of the shear strength and the joint’s positive stress corresponding to the compression-shear state is illustrated theoretically and suggested to be 0.228, conservatively. A reduction factor is suggested for multi-keyed joints, and the contribution of reinforcement to the shear capacity is around 5%. Small confining stress results in slip failure, while large confining stress slows down the degree of shear failure. There is a positive correlation between the shear capacity under slip failure and the confining stress. Finally, the predictive model is validated by simulating the results of slip and shear failures. Full article

Instability in red mud dam bodies is not uncommon. In order to study the stability evolution mechanism during the process of red mud landfill and the deformation characteristics under earthquake action when the landfill site is closed, the deformation law and potential sliding surface motion characteristics of the landfill site were explored based on the finite difference method, revealing the influence of peak ground acceleration (PGA) on red mud deformation. The results showed that: (1) As the height of the red mud landfill increases, the shear force of the red mud landfill gradually increases. Meanwhile, the maximum shear force always occurs near the initial dam, indicating that under the action of gravity, the possibility of shear slip occurring near the initial dam is the highest. (2) The distribution pattern of the plastic zone in the red mud pile during the filling process is relatively complex, and continuous monitoring of the filling process should be carried out to ensure the safety of the filling project. (3) With the increase in earthquake acceleration, the shear force of red mud piles gradually increases. Meanwhile, as the acceleration increases, the maximum shear stress always occurs at the bottom of the initial dam body. Under the action of power, special attention should be paid to the stability of the pile near the initial dam. Full article

In recent years, the advancement of photovoltaic power generation technology has led to a surge in the construction of photovoltaic power stations in desert gravel areas. However, traditional equal cross-section photovoltaic bracket pile foundations require improvements to adapt to the unique challenges of these environments. This paper introduces a new type of photovoltaic bracket pile foundation named the “serpentine pile foundation” based on the principle of biomimicry. Utilizing experimental data, numerical simulation technology was employed to comprehensively investigate the pullout resistance, compressive resistance, and horizontal bearing performance of the serpentine pile foundation. Comparative analysis with traditional square and circular pile foundations revealed the serpentine pile foundation’s significant advantages in all performance indexes. The serpentine pile exhibits a significantly higher ultimate uplift bearing capacity of 70.25 kN, which is 8.56 times that of the square pile and 10.94 times that of the circular pile. This study not only offers valuable technical support for the construction of photovoltaic power plants in desert gravel areas but also holds great significance in advancing the sustainable development of the global photovoltaic industry.

Recent rapid urbanization has led to an increase in tunnel construction, escalating the prevalence of ground collapses. Ground collapses, characterized by large deformation and strain-softening, pose a significant challenge for classical numerical theories and simulation methods. Consequently, a numerical framework combining the material point method (MPM) and strain-softening Drucker–Prager plasticity is introduced in this study to more accurately describe the evolution process and failure mechanism of the subgrade during tunnel excavation. The proposed numerical framework was validated against an analytic solution employing a typical ‘dry bottom’ dam model with solid non-linearity and large deformation; some of the results are also compared with those of the SPH method and centrifugal modeling tests to verify the validity of the MPM method in this paper. The validated model was used in this study to conduct a comprehensive analysis of surface instability and ground collapse under varying soil conditions. This included factors such as strata thickness, cohesion, internal friction angle, and a quantitative description of the development of longitudinal subsidence of the surface. The aim was to clarify deformation responses, failure patterns, and excavation mechanisms, providing insights for underground tunneling practices. Full article

This note studies the correlation between surface and tunnel volume loss in various types of dry soil via finite element method. The effect of small strain stiffness, the buoyancy effect of soil, and tunnel overburden depth are considered in the 2D tunneling model. The results show that both surface volume loss ratio and settlement trough width parameter in the empirical solution can be expressed as a linear equation of tunnel volume loss ratio for 1D overburden shallow tunnels. Furthermore, the surface volume loss ratio can be presented as a non-linear polynomial equation of overburden depth and tunnel volume loss ratio in a 3D space, and this equation holds in different types of soil. The ranges of required fitting parameters and upper and lower bounding surfaces are suggested for various types of soil. Knowledge of this correlation between surface and tunnel volume loss is valuable, as it can be employed in practice for preliminary tunnel design in the absence of tunneling induced maximum ground settlement.
