摘　　要：为保证邻地铁基坑施工安全,依次采取MJS加固施工、钻孔灌注桩施工、水平斜撑施工、逆作衬墙施工处理地下连续墙错缝,顺利完成土方开挖及底板封闭工作。工程实际结果表明,相关施工措施可以使地下连续墙错缝得到妥善处理,可以为类似问题提供参考,以减小基坑风险并保护周边地铁线路和重要构筑物。For the safety of foundation pit construction adjacent subways,staggered joints of underground continuous walls were treated with MJS reinforcement,cast-in-situ bored piles,horizontal diagonal bracings and reverse lining walls,in order to successfully complete earthwork excavation and bottom closure.The actual engineering results show that such measures can improve the staggered joints of underground continuous walls,thus providing a reference for similar issues,in order to reduce risks in foundation pit construction and protect surrounding subway lines and important structures.
