摘要
水文地质勘察是污染场地调查中的关键环节,具有重要作用。本文以某大型化工厂污染场地调查项目为例说明水文地质勘察的重要性,可以查明场地内土层结构,判断含水层和隔水层的位置、厚度等,并为建立场地水文地质模型、设计土壤取样范围和深度、确定地下水监测井设置深度和滤网位置提供科学依据,从而有效节约调查经费,提高调查结果的准确性。
Hydrogeological survey is the key link in the investigation of contaminated sites,which plays an important role.In this paper,the importance of hydrogeological survey is illustrated by the investigation project of a large-scale chemical plant,which can help to confirm different soil layers structure and estimate the position and thickness characteristics of the pervious bed and confining bed.These information can provide important scientific bases for the establishment of hydrogeological model of contaminated site,design of sampling range and depth of soil,determination of depth of groundwater monitoring wells and position of filters.So as to effectively save survey funds and improve the accuracy of survey results.
