摘要
以广州市某基坑工程设计及事故处理为背景,介绍了花岗岩残积层地区采用复合土钉墙支护的工程案例;基坑施工过程中局部区域产生了较大变形,对变形产生的原因进行分析,并提出加固处理方案。基坑监测结果表明,事故的原因分析正确,加固方案可行。
Based on the support and accident treatment of a foundation pit in Guangzhou,the project about the composite soil nail walls for retaining and protecting the granite residual layer is described.The causes of large deformation during the construction of the foundation pit is analyzed,and the project reinforcement is proposed.The monitoring results show that the analysis of causes for the accident is correct,and the reinforcement scheme is feasible.
