Special Issue Information

Dear Colleagues,

In the past 20 years, with the large-scale construction and operation of major transportation infrastructure such as high-speed railways, urban rail transit, urban roads, airports and ports, the corresponding theoretical and innovative level of transportation, geotechnical and underground engineering is rapidly improving and effectively promoting the development of the technical level of planning, design and construction in this field. With the improvement in the construction concept and level, the trends of green practices, safety and energy saving are becoming more and more prominent. It is imperative to adopt new technologies, new methods and new materials to promote the accurate development of geotechnical and underground engineering, which pose new challenges in the construction, operation and management of traffic engineering.

This Special Issue, entitled "Technical Challenges and Countermeasures for the Construction, Operation and Maintenance of Geotechnical and Underground Engineering for Rail Transit", aims to discuss cutting-edge scientific issues in transportation geotechnical and underground engineering; provide an academic exchange platform for scientific and technological workers engaged in design, construction, research and education in this field; share excellent engineering experience and scientific research results; and further improve the level of construction, operation, maintenance and management of geotechnical and underground engineering. This Special Issue covers, but is not limited to, the following topics:

  • Static and dynamic characteristics and theories of rock and soil mass;
  • Interactions between rock and soil mass and underground structures;
  • Green construction and maintenance technology for transportation infrastructure;
  • Intelligent technology for geotechnical and underground engineering in transportation;
  • Vehicle-subgrade (tunnel)–foundation interaction analysis;
  • Traffic infrastructure service status monitoring, evaluation and maintenance;
  • New theory and construction technology for geotechnical and underground engineering design;
  • Tunnel and underground structure life cycle safety operation and maintenance guarantee technology;
  • Disaster mechanism and safety treatment technology for geotechnical and underground engineering.

Deep excavations near subway tunnels can induce deformation, necessitating a comprehensive investigation into causal factors and mitigation strategies. Field measurements were conducted to assess both vertical and horizontal displacements of existing tunnels near a deep excavation in Shenzhen. Utilizing a validated three-dimensional finite element model that considers structure−strata interactions, this study analyzes tunnel displacements, ground movements, diaphragm wall impacts and the sensitivity of enclosure structure parameters. The results indicate that tunnel deformation correlates with enclosure structure deformation, particularly near the center of the pit. Moreover, shallow soil excavation significantly affects the vertical displacement of shallow-buried tunnels. However, the design parameters of the existing enclosure structures inadequately limit tunnel displacement. Therefore, it is crucial to intensify vertical displacement monitoring in shallow tunnels during early excavation stages and to enhance horizontal displacement monitoring during later phases. Implementing measures such as optimizing central support design or retaining soil at the pit bottom helps control maximum horizontal displacement. While support stiffness plays a greater role than retaining wall thickness, its impact on deep excavation projects is limited. Full article
