Special Issue Information

Dear Colleagues,

In geotechnical engineering, stability analysis is considered one of the most important parts in many fields, for example, slopes, underground engineering, foundations and deep excavations. If it is not properly considered, geotechnical structures may collapse, leading to adverse effects economically and on lives. Considering the severe effects, making an accurate stability prediction is greatly important. Currently, there are many methods proposed for assessing geotechnical stability analysis, including reliability analysis, limit equilibrium, limit analysis, slip-line methods, the displacement-based finite element method, etc. However, given the limitation of the assumed simple material model, these methods cannot always make an accurate evaluation. Monitoring can be an alternative way to provide real-time information about geotechnical stability and hence guarantee the safety of geotechnical structures.

This Applied Sciences Special Issue welcomes all new and advanced work on both evaluation and monitoring of geotechnical stability. All papers using new, practical, innovative, and intelligent approaches in either evaluation or monitoring of geotechnical stability are welcome. The fields include but are not limited to slopes, underground engineering, foundations, excavations, and dams. The focus of the Special Issue is on the development of methods for the evaluation and monitoring of geotechnical stability.

Potential topics include but are not limited to the following:

  • Theoretical and numerical methods for geotechnical stability analysis
  • Reliability analysis and new evaluation methods of geotechnical stability
  • New monitoring technologies for the responses of geotechnical engineering
  • Application of big data, artificial intelligence, and machine learning in geotechnical engineering
  • New technologies to increase geotechnical stability
  • Model test of geological stability
  • Case studies of geological stability
  • New materials used in geotechnical engineering

In recent years, shield tunneling has shown many advantages with the development of underground rail traffic. Geological exploration plays a significant role in tunnel engineering, and detailed geological exploration results can guide the successful construction of a tunnel. This research relies on a super large-diameter shield tunnel construction, using microtremor exploration technology to collect data onsite. Combined with a comparative analysis of the borehole surveying, the reliability of microtremor exploration technology is verified. Moreover, the monitoring result of the impact of large-diameter slurry balanced shield construction on the surrounding environment is analyzed. The results show that microtremor exploration can obtain geological details that traditional detection methods cannot obtain, which can predict the possible local geology mutation in front of the tunnel in advance. The law of surface settlement curve conforms to the Peck formula. This can be divided into five stages: micro deformation, extrusion uplift, reciprocating uplift, detachment settlement, and consolidation settlement. The surface settlement on the eccentric loads side is more prominent. The maximum pressure outside the tunnel segment appears on the lower side of the monitoring section, approximately 0.41 MPa, which will increase with the grouting pressure and become stable in five days.
