大断面暗挖车站地表沉降及衬砌应变规律研究

The research of settlement of the earth's surface to concealed-digging the station in big cross section and regulation of structure reaction

在大量施工实测数据的基础上,对大断面暗挖车站地表沉降及结构衬砌应变规律进行了研究,验证了该工法关键工序和关键技术的实施效果,为今后类似工程提供了宝贵的设计与施工经验。

Based on numerous actual measurement datas for construction, considering from big cross section, the paper studys its settlement of the earth＇s surface when a concealed-digging to the station and regulation of structure reaction. Meanwhile, critical working procedure end technique from the labor regulation, their practical effects are verified, which will give a valuable experience for the design end construction of similar projects in the future.
