摘　　要：基坑施工过程中,由于各种原因塌方时有发生,造成了不必要的损失和事故,尤其对相邻道路的影响已成为突出的问题。文章结合实际工程,采用地质雷达技术对基坑坍塌发生后的周边道路进行了探测,经探测,部分道路下方存在空洞、不密实缺陷。从地质雷达图像中,可以清楚地判断出空洞、不密实缺陷的分布情况,探测缺陷部位与基坑坍塌的部位相对应。该方法的普遍应用对分析基坑坍塌对周边道路的影响提供了一个好的解决方法。In the process of affecting the foundation pit construction,due to various reasons,collapse often occurs,resulting in unnecessary losses and accidents,especially the impact on adjacent roads has become a prominent problem.In this paper,combined with the actual project,the GPR technology is used to detect the surrounding roads after the foundation pit collapse.After detection,there are hollow and uncompacted defects under some roads.From the GPR image,the distribution of cavities and uncompacted defects can be clearly determined,and the detected defect position corresponds to the position of foundation pit collapse.The general application of this method provides a good solution for the judgment and analysis of the impact of foundation pit collapse on surrounding roads.
