摘要
结合连云港连云新城金海三期东围堰工程,探讨采用地质雷达方法评估围堰爆破挤淤的效果。通过对雷达图像的解释和分析,获得围堰抛石的具体范围及深度,为爆破挤淤的效果提供评价依据,表明地质雷达对爆破挤淤的探测是行之有效的,提出的介电常数选取范围可供类似工程借鉴。
This paper analyzes the ground penetrating radar（GPR） method in detection of cofferdam blasting toe-shooting effect based on a real example of Jinhai phase Ⅲ east cofferdam engineering in Lianyun new city, Jiangsu province. According to the explanation and analysis of the radar image, we can obtain the specific scope and depth of the cofferdam riprap. It provides the basis for evaluation of the blasting toe-shooting effect and the reference for the subsequent construction. It shows that GPR is an effective method in the detection of blasting crowded silting effect.
