半承压含水层中地下水非稳定流参数计算

摘要

Through acquiring water level and flow and other data in hydrogeological investigation, it establishes geological conception model and math model of semi-confined aquifer, and obtains water permeability coefficient and storage coefficient and other hydrogeological parameters with linear graphic method, which has provided design basis for surrounding structure design and foundation dewatering engineering design.%通过水文地质勘察获取水位、流量等数据，建立半承压含水层地质概念模型和数学模型，采用直线图解法求得渗透系数、贮水系数等水文地质参数，为围护结构设计和基坑降水工程设计提供设计依据。
