Due to rapid construction and limited urban area in Shanghai, some deep excavations are very close to the existing metro tunnels or sensitive superstructures. Therefore the safety of the adjacent tunnels and surrounding structures become an important issue during design and construction of these deep excavations. This paper presents a 3D finite-element modeling using the finite element analysis program...
The excavation of the north square underground shopping center of Shanghai South Railway Station is a complex deep excavation using the top-down construction method. The excavation has a considerable size and is close to the operating Metro Lines. In order to predict the performance of the excavation more accurately, 3D finite-element analyses are conducted to simulate the construction of this complex...
