在堤防质量检测时,地球物理方法能够实现快速、无损的探测,但采用单一物探方法对堤防隐患的判别易产生多解,也很难对堤防质量做出准确分类。本文在分析高密度电法、伪随机流场法和多道瞬态面波法工作原理的基础上,利用综合物探方法探查水库大坝渗漏隐患的详细状况,并确定渗水明流的进水口、渗漏带的平面位置及其发育深度,为堤防质量检测提供了一种新的工作方法。
In the dike quality inspection, the geophysical method can achieve fast and non-destructive detection, but the single geophysical method is easy to discriminate the hidden troubles of the embankment and it is difficult to classify the dike quality accurately. Based on the analysis of the working principle of high-density electric method, pseudo-random flow field method and multi-channel transient surface wave method, this paper uses the geophysical exploration method to probe the detailed conditions of reservoir dam leakage and determine the water inlet , The flat position of the leaking zone and its depth of development provide a new working method for the dike quality inspection.
