Special Issue Information

Dear Colleagues,

While the application of geotechnical research is practical in nature, the improvement of fundamental knowledge of geotechnical engineering and its potential risk or impact when implemented in field applications are key aspects of sustainability in geotechnical engineering. The development of laboratory/field experiments and numerical techniques will improve the sustainable design of geotechnical and geoenvironmental infrastructure. Furthermore, efforts to ensure sustainability in geotechnical engineering should include consideration of reliability and resilience aspects because of the stochastic nature of geomaterials with high uncertainty. Quantifying the uncertainty of geotechnical properties or failure would enable reliability-based geotechnical design.

The Special Issue aims to bring together recent advances in all aspects of geotechnical engineering (e.g., recent progress in laboratory experiments, reliability in geotechnical engineering, advances in numerical methods, etc.) that will potentially contribute to sustainable geotechnical design. In addition to topics related to engineered systems, topics related to environmental and economic issues in geotechnical engineering are also welcome. Relevant topics in this Special Issue could include:

  • Sustainable technologies in geotechnical engineering
  • Geomaterial characterization for sustainability
  • Bio-mediated and bio-inspired geotechnics
  • Environmentally-friendly ground improvement techniques
  • Reliability analysis in geotechnical engineering
  • Geotechnical cost-effective solutions
  • Other recent progress in fundamental knowledge of geotechnical engineering

The present study compares and analyzes three risk analysis models that are applicable to shield tunnel boring machine (TBM) tunneling, and thus proposes an improved risk matrix model based on the causal networks applicable to sustainable tunnel projects. The advantages and disadvantages of three risk analysis models are compared, and causal networks are structured by analyzing the causal relationship between risk factors and risk events. Based on the comparison and analysis results, the causal network-based risk matrix model (CN-Matrix model), which complements the disadvantages and exploits the advantages of the three existing models, is proposed in this paper. Furthermore, this study suggests a means of modifying the weighting scores in the estimation of the risk score, which permits the CN-Matrix model to determine the risk level more reasonably. Thus, the improved CN-Matrix model is more reliable and robust compared to the three existing models. Full article

This study investigated the effect of vegetation plant roots on the stability of the cover slopes of solid waste landfills. A large direct shear test and a root tensile strength test were conducted to quantify the effect of rooted soil of revegetation plants on the increment in shear strength of the soil as a method to protect the cover slope of solid waste landfills. In the large direct shear test, an increase in the shear strength of the ground with the presence of roots was observed, and the root reinforcement proposed in the literature was modified and proposed by analyzing the correlation between the root diameter and the tensile strength according to water content. The stability of the slope revegetation of a landfill facility, considering the root reinforcement effect of revegetation, was calculated by conducting a slope stability analysis reflecting the unsaturated seepage analysis of rainfall conditions for various analysis conditions, such as the gradient, the degree of compactness, the thickness of the cover, and the rooted soil depth of the landfill facility.
