Identification and Gradation of Risk Sources in Subway Station Construction Based on Hole-Pile Method

Abstract

This paper identifies and grades the major risk sources in the Center Street Subway Station in Shenyang, by adopting the Fuzzy Theory to make identification and gradation of risk sources in subway station construction with hole-pile method. By the analytic hierarchy process, it computes the weight and membership of every risk source during the construction process, establishes the evaluation model for identification and gradation of risk sources in hole-pile construction of subway station, obtaines the weights and indictors during the overall construction process of the Center Street Subway Station in Shenyang, and finally determines the danger level in subway station construction under the maximum membership principle. The research gives a reference for hole-pile construction of subway station.
