摘要：毕业设计主要内容是关于上海地铁三门路站的基坑围护结构设计。在基坑围护结构设计前半部分中，根据三门路站基坑所处的工程地质、水文地质条件和周边环境情况，通过施工方案的比选，确定采用地下连续墙作为基坑的主要围护方案，支撑方案选为对撑，从地面至坑底依次设五道钢管支撑，并进行土压力计算、相应的强度和地连墙的配筋验算以及基坑的抗渗、抗隆起和抗倾覆等验算。在计算地下连续墙所受弯矩时，将地下连续墙看做超静定梁用叠加法和弯矩分配法进行计算。23038
在设计的后半部分中，主要是根据场地情况进行基坑变形估算以及基坑的降水设计计算。最后是施工组织的简介。

The design of foundation pit in Shanghai metro line Sanmen road station
ABSTRACT:The graduation design is mainly about the structural design of foundation pit in Shanghai subway Sanmen road station.
In the structural design of foundation pit in the front half part, according to the three road station foundation pit the engineering geological, hydrogeological conditions and the surrounding environment, through the choice of the construction program, to determine the underground continuous wall is used as the main shoring of foundation pit, supporting scheme for support, from the ground to the bottom are provided with five steel pipe support, and the calculation of earth pressure, the corresponding strength and even the wall reinforcement calculation as well as the foundation of the anti permeability, anti uplift and anti overturning and checking. In the calculation of underground continuous wall bending moment, the underground continuous wall as hyperstatic beam superposition method and moment distribution method.
In the latter part of the design, mainly is carries on the calculation of foundation pit precipitation estimation and design of foundation pit deformation according to site conditions. The last is the construction organization.
Keywords: foundation pit; underground continuous wall; construction organization; support system.
