内黄县新建自来水厂水文地质参数研究

Study on Hydrogeological Parameters of New Waterworks in Neihuang County

为了在新建自来水厂的前期勘察工作中高效获取未探明地区的水文地质参数,减少在小范围的水源地场地调查中,因缺少详尽的水文地质资料对工程进展造成的影响,本文基于某新建自来水厂项目,采取工程物探、抽水试验相结合的方式,探明了研究区范围内水文地质参数:渗透系数K及影响半径R。其中,抽水试验所得参数K值处于工程物探推测范围内,具有较高可信度。工程物探和抽水试验为水文地质参数获取及后续工程建设提供了科学的理论依据。

In order to efficiently acquisition hydrogeological parameters of the unproven area in the preliminary investigation of the new water plant,and to reduce the impact of lack of detailed hydrogeological data on the project progress in the small-scale water source site survey,based on a new waterworks project,this paper adopts the combination of engineering geophysical prospecting and pumping test,to explore the hydrogeological parameters in the study area:permeability coefficient K and influence radius R.The parameter K value obtained by pumping test is in the range of engineering geophysical prospecting,which has high reliability.The engineering geophysical prospecting and pumping test provides a scientific theoretical basis for the investigation of hydrogeological parameter acquisition and subsequent engineering construction.
