Stress Field due to Excavation and Development of Excavation Method for the Mountain Subway Station
Abstract: Many complex subway stations were built in Chongqing city of China and the span was very large, in order to study the effect of different excavation order on the stress field in surrounding ground, this paper used Midas GTS software to simulate the different excavation process. Additionally, in order to ensure the excavation stability, the frequently-used methods, i.e. the CD method, the CRD...
