摘要
在介绍探地雷达和瑞雷波探测方法原理和技术特点的基础上,通过浙江温岭东浦新塘和椒江外沙海塘工程检测实例分析表明,探地雷达法和瑞雷波法能较有效地探测堤身和堤基的结构与性质,以及堤身内部不均匀和面板脱空等可能的隐患性质及分布范围,查明海塘渗漏原因。探测结果与现场观察及钻探揭示等情况较符合,对渗漏堤段注浆处理深度的建议在工程实施中起到了较好的指导作用。
The principle and technical characteristics of GPR and Rayleigh wave methods for safety detection were introduced. Case studies on safety detection in the projects of Dongpu dyke in Wenling City and Waisha dyke in Jiaojiang County of Taizhou City of Zhejiang Province show that GPR and Rayleigh wave methods can effectively detect the structure and properties of dyke bodies and foundations, hidden troubles induced by internal non-unlformity of the dyke body, face slab dislocation, etc., and their distribution. Thus, the cause of leakage of sea dykes could be found. The result of detection accords with that from field observation and drilling. Moreover, the suggestion about grouting depth based on the detection mentioned above provides some guidance for treatment of leaky dyke sections in practical projects.
