【 摘 要 】

The leakage water of metro station is an annoying problem, so the quality of concrete construction is the node which is very concerned. This paper combined a new type of induced joint and takes Qingpu station engineering of Shanghai metro line 17 as the background, intends to design and manufacture one special formwork support as a part of waterproof system, which can make the structure of floor and side wall separately constructed. The formwork support is composed by the button steel bracket, the triangle frame of side wall and the combined large steel mould. And through the analysis of three-dimensional finite element simulation, puts forward the new method of combined scheme of induced joint construction.
