综合物探法在病险水库安全评估检测中的应用

Application of Comprehensive Geophysical Exploration Method in Safety Assessment and Detection of Dangerous Reservoir

以某病险水库为例,在概述水库防护堤坝地质情况及病害情况的基础上,提出了高密度电阻率法、探地雷达和激发极化法、超声波对穿测试等相结合的综合物探检测思路,并对土坝防护堤及防渗墙等病害进行了探测评估。结果表明,在选择水利工程综合物探技术时,必须选用不同物性参数的物探方法组合应用,力求从不同物探参数角度反映地质体实际情况,使探测信息更加丰富完整,更具解释性。

Taking a dangerous reservoir as an example,on the basis of summarizing the geological conditions and diseases of the dam for reservoir protection,this paper puts forward a comprehensive geophysical detection method,which combines high-density resistivity method,ground penetrating radar,induced polarization method and ultrasonic penetration test,Furthermore,the defects of Earth Dam breakwater and cut-off wall are detected and evaluated.The results show that it is necessary to select a combination of geophysical methods with different physical parameters,so as to reflect the actual conditions of geological hydraulic engineering from the perspective of diferent geophysical parameters,which makes the detection information more abundant and complete,more explanatory.
