综合物探方法在堤防质量检测中的应用

Application of integrated geophysical method in quality detection of dikes

在堤防质量检测中,地球物理方法能够实现快速、无损的探测,但采用单一物探方法对堤防隐患的判别易形成多解,也很难对堤防质量做出准确分类.本文中应用探地雷达、高密度电法、地震勘探等综合物探方法对大源渡堤防质量进行检测,并以龙荫港以例,通过综合三种物探方法互相参照、相互验证,互为补充,查明了堤防隐患的分布位置与埋深,为堤防质量检测提供一种新的工作方法.

In the quality detection of Dikes, the geophysical method could carry out fast, undamaged detection. It would form multiresolution easily if adopting single geophysical prospecting method to distinguish dike hidden fault, and it also very difficult to do the accurate classification to the dike quality. This article applies the intergrated geo physical prospecting method such as GPR, high-density resistivity method and seismic prospecting to detecting the DaYuanDu dike quality. It also takes the LongYi port as example, and through integrating these three geophysical prospecting method to consult, validate and supplement each other, then it finds out the locality and buried depth of dike hidden faults, and provides an new working method to the dike quality detection.
