激电测深法划定海水入侵界线研究
Study on delineating seawater intrusion boundary using induced polarization sounding method:a case study of Hongdao Bay New Area
摘要
Abstract
Seawater intrusion is one of the typical geological safety risks in coastal cities.In this study,induced polarization sounding tests and hydrochemical analysis experiments were carried out in Hongdao Bay New District of Qingdao.By establishing a power function correlation model between apparent resistivity and chloride ion mass concentration,the apparent resistivity threshold for severely seawater-intruded areas in Hongdao Bay New District was determined to be 8.2 Ω·m.Finally,combined with the measured apparent resistivity results from induced polarization sounding,the delineation of the seawater intrusion boundary in the Hongdao Bay New District was completed.The area of the severely seawater-intruded area in Hongdao Bay New District is approximately 41.2 km2,accounting for 55.9%of the study area.The area with slight seawater intrusion covers approximately 8.1 km2,accounting for 11.0%of the study area.关键词
