| Abstract: | Most subway stations in Shanghai were constructed in succession,in which the end well of station was designed relatively big. Excavation of base tunnel regularly begins with the end well,so it is very important to take a correct excavation scheme. Combined witch the technical parameters in construction,this article mainly discusses the excavation method of deep end well of subway station, the "Time-Space Effect" principle and the support system in case of complicated large span foundation. |
