摘要 深圳中信地下商场位于城市繁华地段,地面交通繁忙、地下管线密布,工程地质、水文地质条件复杂,因此采用了以浅埋暗挖和洞内加固为主的施工技术。文章重点介绍了超大管棚预加固技术、开挖方法的研究及优化、二次衬砌的体系转换及监控量测,对其他城市地下空间的开发具有一定的借鉴价值。 hallow mining excavation was adopted for the Shenzhan Zhongxin flat roof multi-span underground stores under busy streets with many kinds of pipeline facilities beneath them and with complex geologic and hydro-geologic conditions.The paper introduces in detail the pre-reinforcement technology by ultra large pipe-roofing,the study and optimization of excavation method,the system conversion of the secondary lining and monitoring.This can be taken for reference by other cities for the development and utilization of urban underground space.
