上海市水利泵闸工程的基坑设计研究与探讨

Analysis and discussions on pit design for pump-gate projects in Shanghai

水利泵闸工程的主体结构大多位于已有河道中,其特有的设计边界条件决定了其基坑设计不同于传统的市政、建筑工程的基坑设计,围绕水利泵闸工程的技术特点和难点,从基坑的平面布置、围护结构的选型、施工顺序安排、稳定性验算、数值模拟等方面进行研究分析,并列举上海市已成功应用的典型案例,为类似工程的应用提供技术参考。

The main structure of a pump-gate project often located on the river bed, the design is different from the conven- tional foundation pit project for its special boundary conditions. This paper analyzes the characteristic and difficulty of pump- gate projects in Shanghai, and put forward the design strategies including foundation pit plane layout, the types of retaining structure, construction procedure and numerical simulation. The successful application experiences of engineering cases in Shanghai provide a reference to the similar engineering projects.
