First introduced the various open applicable range and advantages and disadvantages of different types of supporting structure, through the various aspects to explore suitable for the foundation pit excavation supporting plan, according to the actual situation is potting soil nail wall + SMW pile + pre stressed composite structure for foundation pit retaining structure of anchor supporting. Start to set up before all the relevant parameters, and then to calculate earth pressure calculation, calculated on the upper part of soil nailing wall of foundation pit design, calculation for the local stability; Then in SMW pile and pre stress anchor design, calculate the stability of the stru...
