Application of Analytic Hierarchy Process in the Selection of Subway Construction Method

Abstract

In order to select a better method of subway construction, this paper uses the hierarchical weight decision analysis method to analyze and study the methods of CRD, PBA (pile-beam-arch), middle hole method and double sidewall guide pit method. The comparison results show that PBA method is the best construction method. It is proved that the index system and evaluation model constructed in this paper are reasonable and operable. Therefore, the method proposed in this paper is effective and can be used as a reference for the comparison and selection of subway stations in the construction stage in the future.
