摘要： 为了避免岩溶发育诱发的地质灾害对于桥梁桩基工程的安全施工和运行所造成的危害，通过介绍地质雷达检测的原理、方法及检测过程中相关参数的选择，并结合实际工程，利用地质雷达点测法，研究了桥梁桩基下岩溶发育引起的溶洞的位置及规模，对所测地质雷达图像进行了分析解释。研究结果表明：地质雷达探测技术可以有效地查明桥梁桩基底部岩溶发育的位置及规模，为制定治理方案提供了重要参考依据。

Abstract:  In order to avoid the geological casualty induced by the development of karst for bridge pile foundation construction, the ground penetrating radar(GPR), a new electromagnetic method and its basic principles and techniques and the selection of correlative parameters in detection were introduced, was used to study the location and scale of karst caves by point measurement based on an actual project. Then the ground penetrating radar image was analyzed. Study showed that the location and scale of karst cave under the bridge pile foundation was detected by GPR, which was provided as the reference for its treatment.
