单侧墙体支架体系在PBA工法暗挖车站的应用

On the application of the single-side wall support in PBA technique used in the excavation station

结合工程实例,阐述了PBA工法的总体施工顺序,对单侧支架体系作了总体概述,就侧墙施工要点进行了总结,通过经济对比分析表明,PBA工法双层车站侧墙采用单侧墙体支架体系进行施工取得了较好的经济效益。

Combining with the practical examples, the paper illustrates the general construction sequence of the PBA technique, gives a general survey on the single-side wall support system, and summarizes the single-wall construction. According to the economical contrast analysis, it is proved that the single-side wall support system can be used in the single wall of the two-storey station with PBA technique and its application has better benefits.
