摘要
结合某地下车库基坑工程实例,从施工工艺、水文地质条件等多方面对深基坑止水帷幕失效的原因进行了详细的诊断分析。针对常规止水帷幕失效处理措施存在的局限性,在对场地地层中的潜水、承压水等不同类型地下水的分布、特性及其降水对周边环境影响的分析的基础上,提出了有针对性的止水帷幕综合处理措施。基坑施工全过程的各项监测数据表明,在研究和分析了场区内地下水特性的基础上制定的止水帷幕失效综合处理措施是十分安全、经济、有效地,可以为类似的工程提供有益的参考。
Combined with an engineering example,this paper analyzes the cause of water stop curtain failure in deep foundation pit and puts forward the corresponding measure for its treatment based on the research of distribution and properties of the phreatic aquifer and artesian water.The monitoring result indicated that the treatment measures of water stop curtain failure based on the research of the properties of groundwater is perfectly safe,economical and effective and can supply helpful reference for similar engineering work.
