连云港某软土基坑滑坡分析与整治方法研究

On landslide analysis and rectification measures of soft soil foundation pit in Lianyungang

针对连云港某软土基坑围护不当导致的基坑滑坡事故,采用钻探、取样、室内试验、水平位移监测等手段,查明基坑侧壁软土的物理、力学性质,分析滑坡产生的原因,通过多种方法综合确定基坑侧壁软土滑动带的位置,提出滑坡整治措施,并对整治结果进行分析验证。

In light of the foundation pit landslide caused by improper enclosure protection in the soft soil foundation pits in Lianyungang,the authors identified the physical and mechanical properties of soft soil in lateral walls of foundation pit and analyzed the reason of the landslide through drilling,sampling,laboratory test,horizontal displacement monitoring and other means. By variety of methods,sliding positions in lateral walls of the foundation pit were determined comprehensively,regulation measures of landslide were proposed,and results of regulation were analyzed and proved.
