湖口县双钟圩堤滑塌灾害综合物探调查效果及地质原因分析

THE EFFECT OF COMPREHENSIVE GEOPHYSICAL SURVEY ON DAM SLUMPING DISASTER IN SHUANGZHONG COUNTRY FAIR OFHUKOU COUNTY AND AN ANALYSIS ON ITS GEOLOGICAL CAUSE

本文在简单介绍地质雷达与高密度电法的工作原理及被查堤坝的地球物理参数特征的基础上 ,对湖口县双钟圩堤综合物探调查资料作了详细的分析解释 ,说明了综合物探方法在探查堤防工程隐患的实用效果 ;从探测结果与坝基的工程地质条件出发 ,着重阐明了该堤滑塌的地质原因与诱因 ;同时提出了对该堤的处理方法和目前正在带病运行的堤坝进行检测方法和必要性。

Based on a brief description both of the working principles of ground penetrating radar (GPR) and high-density electrical method, and of the geophysical parameter characteristics of the surveyed dam in Shuangzhong Country Fair of Hukou County, a detailed analysis and interpretation has been made of the data collected from comprehensive geophysical survey of the dam in question. This has helped to explain the practical effect of comprehensive geophysical method in finding out hidden danger of the dam works. Based on the survey result and the engineering geological conditions of the dam foundation, this paper lays emphasis on the geological cause and triggering factor for dam slumping, and proposes an appropriate method of treatment, pointing out the necessity of working out a method to check the dam which is now in operation under a halting state.
