전기비저항을 이용한 수리시설물의 안정성 연구

Abstract

The domestic dam are that it is vulnerable to the water leak by deterioration of central clay and various reasons. This study attempts to identify the stability of central clay which forms body of most dam. Clay soil exists in the center of dam body in order to prevent water, the condition of this part becomes the core of stability of whole dam body and the fact whether it leaks or not. This study conducted dipole-dipole array resistivity survey to determine the stability of central clay & base in the dam body. Where, Heterogeneous part is that it can't perform the function of central clay preventing water, and it could become the cause of water leak and problem of stability of dam body as the central clay is transform or washed away by constant pressure as regards upstream pondage of dam body. This transformed central clay & base shows more changes in the resistivity value than stable part. The purpose of this study is to identify the part which causes the problem of stability of dam body through resistivity prospecting in the Jang-Sung Gun water dams.
