综合物探技术在复杂土质堤防隐患探测中的应用

Application of Comprehensive Geophysical Prospecting Technology in Detecting Hidden Danger of Complex Soil Dyke

在堤防隐患探测中,地球物理方法具有快速、经济、无损等优点,但因堤防工程结构复杂以及隐患的分布和类型复杂多变,常用的单一物探方法都有其局限性与不足之处,无法全面解决堤防探测中的隐患分布问题。以黄河下游某堤防工程的隐患探测为例,综合应用地质雷达法、高密度电法和面波法等综合物探方法进行隐患探测结果表明,不同方法之间互为补充,可较为全面地解决堤防探测中隐患的特性和分布问题。

In the detection of dike hidden danger,geophysical method has the advantages of fast,economic and nondestructive.However,due to the complex structure of dike engineering and the complex distribution and types of hidden danger,the common single geophysical method has its limitations and shortcomings,which can not solve the problem of dike hidden danger distribution in an all-round way.In this paper,taking the hidden danger detection of a dike project in the lower Yellow River as an example,the comprehensive geophysical methods,such as geological radar method,high-density electrical method and surface wave method were used to detect the hidden danger.Different methods referred to each other and complement each other,so as to comprehensively solve the characteristics and distribution issues of the hidden danger.At the same time,it also provided some reference for the selection of methods to solve similar hidden danger detection issue.
