Abstract

Abstract:

The foundation pit retaining design is an important and complex work. The drawup support methods of foundation pit of Metro station in Shenyang are evaluated and analyzed by means of step analysis and fuzzy comprehensive evaluation principle, and rational retaining type and retaining parameters are obtained. Meanwhile, the calculation process of optimization and analysis by means of value engineering principle is presented, and the cost variation laws of sloping and soldier pile retaining and steel support and anchor support in silty clay and sandy stratum.

Key words: foundation pit, step analysis, fuzzy comprehensive evaluation, optimization design
