“上海协和城二期”工程位于上海市南京西路2066号,工程周边情况复杂,且运行中的地铁2号线横穿本工程,另外基坑开挖深度范围内的工程地质和水文地质条件极差。针对本工程特点,说明本工程基坑降水必要性分析及降水设计总体思路、具体设计方案,详细阐述了本工程基坑降水的关键技术、降水实施效果及影响分析。为同类工程提供了一些借鉴。
“Shanghai Concord City Phase II ” project is located at No. 2066 Nanjing West Road, Shanghai. The surrounding area of the project is complicated and the subway line 2 running is traversing the project. In addition, the engineering geology and hydrology within the excavation depth of the foundation pit Very poor geological conditions. According to the characteristics of this project, this paper analyzes the necessity of precipitation in foundation pit and the general idea and design of precipitation design. The key technologies of foundation pit dewatering, the implementation effect and impact analysis of precipitation are elaborated in detail. For similar projects provide some reference.
