摘　　要：以一个典型工程为研究背景,通过结构试验来测定嵌岩地下连续墙嵌岩段基岩的m值,利用最小二乘法拟合了开挖时基坑支护的变形监测数据,并对基岩的m值进行反分析,研究结果表明对于超深开挖的嵌岩地连墙支护结构,其设计和施工不能完全分开,应根据现场施工监测对设计作出调整。With a typical engineering as research background,the m value of underground continuous wall rock socket section was determined by structural test,the excavation foundation supporting deformation monitoring data was fitted with least square method,the bedrock m value was back analyzed.The research result indicated that the design and construction of super deep excavation rock socket continuous wall supporting structure was not be divided,the design should be regulated according to field construction monitoring.
