地铁隧道穿越断裂带施工技术

摘要

Combined with the example of Urumqi subway tunnel construction engineering,the paper introduces construction technology of metro tunnel crossing fault geological zone,some countermeasures are mainly used in construction such as advanced geological forecast,full-face curtain grouting to effectively overcome the poor stability of rock mass,which would lead to the ex-cavation risk big,and be easy to collapse.This can providea areference for future similar geological tunnel construction.%结合乌鲁木齐地铁隧道工程施工实例，对地铁隧道穿越断裂带不良地质施工技术进行介绍，施工中主要采用超前地质预报、全断面帷幕注浆等措施，有效地克服了岩体稳定性差、开挖危险性大、极易坍塌等不利条件，为以后类似地质隧道施工提供参考。
