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。 In this paper, a seawall in eastern Zhejiang is taken as an example. According to the characteristics of the project and the specific analysis of the exploration environment, aiming at the obvious nonuniform settlement and fissure of partial embankments and the phenomenon of leakage at high tide, Leibo method basically identified the status of the seawall structure and the existence of abnormal body layer (surface) and uneven place. Combined with the design tide level and dike elevation analysis, these anomalies are potential leakage channels and may even lead to the result of slump.
