摘　　要：结合工程实例,阐述了地质雷达在探测基坑开挖影响区域中的应用,并结合数值模拟方法对探地雷达图像解释结果进行了验证。对比分析可见两种方法所得的土体滑移位置具有良好的一致性,表明了探地雷达具有快速有效地确定基坑开挖影响区域的能力,是一种快速检测坑边地基病害的有效方法。Combined with projects, it illustrates the application of geological radar in the exploration of the area influenced by foundation pit exeavation. Meanwhile, it testifies the result illustrated by geological radar diagram combined with numerical simulation method. The comparative analysis shows that the soil body sliding locations by the two kinds of methods are consistence, which proves that geological radar is able to make out the area influenced by foundation pit excavation fast and effectively and it is also an effective method to examine the problems of the foundation surrounding the pit.
