摘要

以假定地铁站为工程背景

采用目前施工地铁站较为普遍的逆作法与洞桩法分别进行施工。为对比分析两种工法施工地铁站引起的位移

应用数值分析方法对逆作法和洞桩法在分跨开挖方式下修建地铁站的施工过程进行模拟。经计算有限元模型

得出两种工法在分跨开挖方式下施工地铁站引起的地表沉降、侧桩水平位移、底板隆起的对比图。通过分析位移对比图

得出洞桩法施工地铁站在位移控制方面优于逆作法的结论

从而深化对逆作法与洞桩法施工地铁站作用机理的认识

以期为类似工程提供参考。

Abstract

Taking a typical subway station as engineering background

the two common construction methods

top-down method and hole-pile method

are adopted to simulate the excavation of the subway station.In order to analysis the displacement caused by top-down method and holepile method

the numerical analysis technique is adopted to simulate the construction process of the subway station excavated in span with these two methods separately.Comparison charts of surface settlement

lateral horizontal displacement of piles and floor uplift are obtained by computation.The simulation result shows that the hole-pile method is superior to the top-down method in controlling displacement.The research can help deeply understand the mechanism of top-down method and hole-pile methods

and provide valuable reference for similar projects.
