Special Issue Information

Dear Colleagues,

This Special Issue focuses on the mechanical properties and failure behavior of underground structures, including a variety of facilities such as caverns and tunnels. It investigates how external loads, such as earthquakes and explosions, affect the stability of these structures, analyzing their dynamic responses and failure mechanisms under such conditions. Furthermore, this Special Issue addresses the stress conditions that must be taken into account during the design and construction of underground facilities, as well as effective strategies to improve their stability and safety. Through this collection of research, valuable insights into the mechanical responses of underground structures will be provided, which can also offer guidance for the safe design and construction of underground projects.

We are pleased to invite you to present your research and development outcomes in the form of research articles or reviews covering the following areas:

  1. The analytical and numerical modeling of underground structures;
  2. Experimental studies on underground structure performance;
  3. Design and construction techniques for underground structures;
  4. Case studies of underground structure failures;
  5. The durability and long-term performance of underground structures;
  6. The mechanical responses of rock and concrete in underground structures;
  7. AI in underground structures;
  8. Prediction and support for geohazards affecting underground structures;
  9. Induced seismic activities when collecting geothermal energy and shale gas.

This study presents a peridynamic model formulated using the micromodulus function and bond deformation. The model is derived by establishing energy equivalence between a modified virtual internal bond (VIB) and a peridynamic bond. To address surface effects in peridynamics, a stress-based correction method utilizing nodal stress is introduced, enhancing the model’s numerical accuracy. The model was implemented using an in-house Cython code and validated through the following numerical examples: a plate under traction, a plate with a hole under displacement boundary conditions, a uniaxial compression test on granite with a deformation-based mixed-mode bond failure criterion, and a comparison with an existing strain-based peridynamic model. For the plate under traction, the deformation-based method performed similarly to the strain-based model in the loading direction and better in the unloaded direction. The stress concentration obtained from the proposed model (240 MPa) near the hole in the rectangular plate simulation differed from FEM (252 MPa) by 4.7%. The granite test predicted a UCS of 111.88 MPa and a Young’s modulus of 20.67 GPa, with errors of 0.1% and 1.57%, respectively, compared to the experimental data. Full article

A deeper understanding of the fracture evolution of hole-containing rocks is helpful for predicting the fracture of engineering rock mass. Based on this, uniaxial compression tests and two-dimensional numerical tests were conducted on red sandstone containing three different shapes of holes before and after reinforcement. The mechanical properties, stress field evolution, and AE energy and AE events during the sample fracture process were studied. The conclusions are that: (1) The reinforced specimens exhibited a significant increase in Young’s modulus and strength compared to the unreinforced specimens (containing a semicircular arch hole). (2) The sample always cracks from the loaded axial direction of the hole, presenting as tensile cracks. Subsequently, stress concentration at the corners of the hole results in shear cracks. Finally, the cracks gradually expand and merge with the holes; there are obvious macroscopic cracks and fracture surfaces on the sample surface, which proves that the sample has been fractured. (3) The reinforcement of the hole-containing sandstone can effectively inhibit the expansion of cracks in the rock. (4) When the stress on the specimen is less than its peak stress, the accumulation of the AE energy and AE events in the reinforced sample are greater than those in the unreinforced sample. The specimen experiences more intense compression-induced fracturing and has a stronger load-bearing capacity. Full article
