摘　　要：钱塘江海塘根石探测可采用多种综合物探方法。在综合调研国内类似项目经验的基础上,收集、测定了主要目标地质体的物性参数,通过数据采集、解释推断,并采用摸探、钎探等方法对根石异常进行了验证,证实可采用以高密度电阻率法为主,地质雷达为辅的探测方案。并推荐了地质雷达探测根石的主要技术参数,提出采用融合温纳、施伦贝谢装置数据进行反演可以提高探测效果的建议。Many comprehensive geophysical methods can be used to detect root stones in Qiantang River seawall.Based on the comprehensive investigation of similar projects,the physical property parameters of the main target are collected and determined,and the root stones anomaly is verified by data acquisition,interpretation and inference,exploration and brazing.It is proved that the detection scheme with high density resistivity method as the main method and geological radar as the auxiliary can be adopted.The main technical parameters of GPR are recommended,and the suggestion is put forward that the inversion of data by Wenner and Schlumberger devices can improve the detection effect.
