摘　　要：国内外堤防渗漏探测的物探方法多侧重于渗漏点的探寻与查找,较少开展划分堤防渗漏强弱区段的探测。在有限的资源条件下,为对堤防进行评估和治理,往往需查明其渗漏的强弱,有针对性的采取措施。对于此类问题的解决,单一的探测方法往往难以达到预期的效果。为解决此类问题,文章结合在某堤防渗漏探测实例实践中,尝试采用联合剖面法与伪随机流场法相结合的综合探测方法开展对堤防渗漏的探测,并通过2种探测方法结果的相互印证、联合分析,较为准确地区分了探测堤段各部分的渗漏强弱。实践证明,联合剖面法与伪随机流场法相结合的综合探测方法在堤防渗漏强弱探测中可行、有效,可作为今后此类问题的解决方法。The geophysical prospecting methods of dyke leakage detection at home and abroad mostly focus on the search of the leakage point,and rarely conduct the detection for the zoning of dyke leakage strength.Under the condition of limited resources,in order to evaluate and manage the dike,it is necessary to define the strength of the leakage and take targeted measures.Single detection method is usually insufficient to achieve the desired results for the solution of such problems.In order to solve this kind of problem,combined with the example of a dike leakage detection practice,the article tried to use the composite profiling method and the pseudo-random flow field method to carry out a comprehensive detection of the dike leakage.Mutual verification and joint analysis of the two methods can accurately define the leakage strength of each section of the dyke.Engineering practice has proved that the combined detection method of the composite profiling method and the pseudo-random flow field method is feasible and effective in detecting the leakage strength of dykes,and it can be used as a solution for such problems in the future.
