| Abstract: | Taking the deep foundation.pit support engineering at the station of Jianchangdao of Tianjin Metro Line 5 as an example, this paper analyzes the calculation principle of CSM method and studies the design of shaped steel and cement-soil mixed wall, and the calculation of both pulling force of the shaped steel and floating resistance. The results show that CSM method is safe and feasible, in respect of which the wall plugged in with shaped continuous wall as deep steel leads to high construction efficiency and may be substitute for traditional foundation pit support structure, and worthy of wide application. |
