弱透水层释水,污染物迁移转化及高危废物深埋选址等水文地质和工程地质活动中,孔隙溶液的地球化学行为越来越受到重视。但孔隙溶液提取技术研究发展相对缓慢。介绍了目前应用较多的孔隙溶液提取技术,及其应用局限性与适用条件。综述了孔隙溶液在地球化学、土壤学、环境地质及水文地质学中的应用现状,并提出在地下水越流计算,弱透水-含水系统相互作用,地下水年龄问题研究上,孔隙溶液的测试分析具有良好的应用前景。
Geochemical behavior of pore water has attracted more and more attention in hydrogeology and engineering geology activities,including pore water released from an aquitard,migration and transformation of pollutants,and the reposition of high radioactive waste.However,the advance and development in the studies of extraction methods of pore water are relatively slow.This paper reviews the main commonly used methods for pore water extraction,potential artifacts from their use and the applicable conditions.An overview on the application of pore water in geochemistry,soil science,environment geology and hydrogeology is provided and the prospect studies of pore water on leakage,interaction in an aquitard-aquifer system and the age of groundwater in hydrogeology is also proposed.
