摘要
水库及大坝年久失修,不断发育的裂隙导致渗漏,严重威胁着附近村民的生命财产安全。由于水库坝基地形起伏、地势险峻、裂隙发育的复杂条件,选用三极电测深、三极电剖面和音频大地电场综合勘探方法对水库坝基和左、右坝肩部位进行详细探测。根据物探资料,并结合坝体周围地质条件和渗漏调查情况综合分析,查明了裂隙分布及渗漏位置,为后期钻探及加固防渗提供必要依据。
The reservoir and dam have been for long years and without repairment,the continued development of fractures lead to leakage,which threats seriously the life property safety of people near country.For the complicated conditions of topographic relief,terrain steep and developed fractures.This paper applies tri-electrode sounding;three poles profiling and audio geoelectric field method to detect dam foundation,left and right dam abutment of Gutai reservoir detailedly.According to the detection data,with geological conditions surrounded dam and survey condition of leaking,and find out the distribution of fractures and location of leaking,and offers the necessary gist for the later drilling,reinforcement and preventing leakage.
