摘要
水下深基坑承压含水层的水文地质参数主要通过现场抽水试验,并结合理论计算分析综合确定。文章结合竺山湖隧道工程勘察实例,以水上抽水试验原始数据为基础,通过稳定流和非稳定流的几种常用计算方法进行综合分析比较,确定了合理的水文地质参数,并对涌水量进行了估算。
The hydrogeological parameters of confined aquifer in underwater deep foundation pit are mainly determined by field pumping test combined with theoretical calculation and analysis.In this paper,combined with the engineering investigation example of Zhushan Lake Tunnel,based on the original data of water pumping test,through the comprehensive analysis and comparison of several common calculation methods of steady flow and unsteady flow,the reasonable hydrogeological parameters are determined,and the water inflow is estimated.
