General Report on Technical Session 4B: Deep Excavation, Tunneling and Groundwater controlling

摘要

The General Report reviews a total of 27 papers related to deep excavation, tunneling and groundwater controlling form 17th international conference on soil mechanics and geotechnical engineering. A total of 11 papers in the sub-theme of tunneling covers four subjects including ground movement and its effect on adjacent existing structures, ground treatment, hazard and risk management, and face stability. A total of 9 papers in the sub-theme of deep excavation session covers two main aspects of excavation engineering, of which one is design and construction, and the other is performance and new seepage control technology in excavation. A total of 7 papers in the sub-theme of groundwater controlling covers two aspects of groundwater, of which one is groundwater control during underground construction and the other is treatment of contaminated groundwater. In particular, some advances and research topics on safety of tunneling, deep excavations, and groundwater control during excavation in China are introduced.
