摘　　要：本文以浙东某海塘为例,针对其局部堤段存在的明显不均匀沉降和裂损,以及高潮位时出现渗漏的现象,通过工程特点和探测环境的具体分析,采用探地雷达和瑞雷波法基本查明了海塘结构现状及堤身内存在的异常层(面)和不均匀处。结合设计潮位和堤顶高程分析认为,这些异常处是潜在的渗漏通道,甚至可导致滑塌等结果。Based on the detecting example to Certain Sea Dyke Project and on the non-uniform settlement, fracture and seepage of the part dyke, it is indicated that the reason of the seepage, the structure and character of the body and the basement of dike could be detected effectively by GPR and Rayleigh wave methods. Through the analysis on the design tide level and the elevation of the dyke, it is thought that the abnormal spots are the potential seepage path which may result in the slide and collapse of the dyke.
