某市地下污水处理厂深基坑支护及地下水控制工程实践

Engineering Practice of Deep Foundation Pit Support and Groundwater Control in Underground Sewage Treatment Plant of a City

该文以某市地下污水处理厂深基坑支护及地下水控制工程为例,根据场地工程特点,对深基坑支护设计与地下水控制设计方案进行了介绍。经监测表明,基坑的水平垂直位移、深层土体位移、周边建筑物及管线的变形均处于正常范围内,地下水位变化正常。说明本工程的基坑支护及地下水控制是成功的,对同类型基坑支护、降水工程具有一定的借鉴意义。

Taking the deep foundation pit support and groundwater control project of an underground sewage treatment plant in a city as an example, this paper introduces the deep foundation pit support design and groundwater control design scheme according to the site engineering characteristics. The monitoring shows that the horizontal and vertical displacement of the foundation pit, the displacement of deep soil, the deformation of surrounding buildings and pipelines are all within the normal range, and the groundwater level changes normally.It shows that the foundation pit support and groundwater control of this project are successful, which has certain reference significance for the same type of foundation pit support and dewatering engineering.
