南京某深基坑工程降水试验分析

Pumping Test Analysis of a Deep Foundation Pit in Nanjing

基坑开挖过程中的地下水降排往往会影响到基坑安全和环境安全等诸多问题。为消除或减弱该类风险,开展了专项水文地质试验。本文列举了基坑环境水文地质评价的主要内容,分析基坑地下水控制引起的环境变化,提出基坑工程地下水控制措施的建议,为类似基坑工程的地下水控制分析提供了借鉴意义。

The groundwater pumping in the foundation excavation tend to affect many problems including the excava -tion safety and environmental safety .In order to eliminate or reduce the risks ,a special hydrogeological test is carried out.In this paper,the main contents of the environmental hydrogeological evaluation of foundation pit are listed ,the envi-ronmental changes caused by the groundwater control of foundation pit are analyzed ,and the suggestion of the groundwa-ter control measures for foundation pit engineering is put forward ,which provides a reference for groundwater control anal-ysis of similar foundation pit engineering .
