摘要
上海长江西路隧道浦西工作井紧邻地铁3号线和逸仙路高架,其周边环境及水文地质条件复杂,在其基坑开挖期间,地下水控制难度极大。为消除或减弱该基坑地下水引起的基坑安全风险及环境风险问题,开展了专项水文地质试验,进行了基坑环境水文地质评价,评估了相应水文地质条件及地下水引起的环境变形问题,分析了基坑地下水控制的难点及风险,进而提出了基坑地下水控制的建议措施。本文为类似基坑的基坑工程地下水控制分析提供了借鉴意义。
The Puxi working well of west Yangtze road tunnel in Shanghai is adjacent to subway line No. 3 and Yixianlu viaduct, the surrounding environment and hydrogeological conditions are complex. The control of groundwa ter is difficult during the excavation of foundation pit. In order to eliminate or reduce risk of foundation and environ ment safety caused by groundwater, special hydrogeological test is carried out, a hydrogeological evaluation is con ducted, the corresponding hydrogeological conditions and environmental deformation caused by groundwater are eval uated, the difficulty and risk of groundwater control is analyzed and the measures of groundwater control are proposed. This article provided reference to analysis of groundwater control in similar foundation pit engineering.
