沈阳地铁2号线会展中心站工程降水方案论述

Discussion on Dewatering Scheme of Shenyang Metro No.2 Line Exhibition Center Station Project

为保证地铁基坑的顺利施工,工程降水往往是地铁建设中的不可缺少的部分,其直接影响基坑施工的安全,控制工程建设周期,在整个工程建设中作用重大。依据工程现场的水文地质条件,选择适宜的降水和排水实施方案,对基坑涌水量、单井出水量进行计算分析,确定降水井结构及成井要求,阐述降水的辅助及补救措施。

In order to guarantee the smooth construction of foundation pit for metro,the engineering dewatering is often a necessary component in the metro construction,which directly affects the safety of pit construc-tion,controls the engineering construction period,and plays a significant role in the whole engineering construction.According to the hydrogeological condition of the engineering field,the suitable dewatering and drainage implementation scheme is selected.The article calculates and analyzes the water inflow of foundation pit and the water yield of single well,determines the structure of dewatering well and the requirement of well construction,and sets forth the auxiliary and remedial measures of dewatering.
