基坑工程常见险情分析与处理措施

摘要

This paper introduced the main destructional forms of foundation pit engineering and discussed the usual danger and corresponding measures of foundation pit engineering construction process. According to the situation that one pit in Beijing will collapse,the text successfully excluded the danger by making bulldozing backpressure to slope angle,adding anchor,cutting off sewers and hardening ground etc.,then the text using further reinforcement that ensure the safety of the pit. An efficiency “security contingency plans” should be established according to the character of the project before construction of foundation pit engineering to ensure the safety of foundation pit engineering,at the same time foundation pit engineering risk management system should be strictly enforced.%介绍了基坑工程的主要破坏形式，探讨了基坑支护施工过程中常见的险情及相应处理措施。针对北京某基坑即将坍塌的情况，通过采取对坡角进行堆土反压、加设地锚、截断污水管、硬化地面等措施，成功排除了险情，并采取进一步的加固措施，保证了基坑的安全。基坑工程施工前要针对项目特点，建立行之有效的“安全应急预案”，严格执行基坑工程风险管理制度，确保基坑工程安全。
