为进一步提高基坑工程风险性防范意识,笔者以上海某基坑坍塌事故为例,从设计、施工、监理、监测角度对基坑坍塌事故进行全方位剖析,并对基坑原设计方案的安全稳定性进行了验算。最后总结出降低基坑工程风险的对策,相信能为今后基坑工程设计、施工、监测等参建各方提供有益的参考。
In order to further enhance the awareness of pit excavation risk prevention, the author takes a foundation pit collapse accident in Shanghai as an example to conduct a comprehensive analysis of pit collapse accidents from the perspectives of design, construction, supervision and monitoring, and to analyze the safety of the original pit design plan Stability has been checked. In the end, the countermeasures to reduce the risk of foundation pit engineering are summarized, and it is believed that it can provide useful reference for all parties involved in the design, construction and monitoring of foundation pit engineering in the future.
