地质雷达对地下空洞等异常地质的探测成果可有效避免城市地铁建设对周边环境和施工安全产生的不良影响。本文介绍了地质雷达的构成和测量原理,利用地质雷达对城市地铁建设途经部分路段地下地质情况进行了探测,针对探测成果对地下空洞位置、深度、面积等基础地理信息资料进行了分析,为制定地下空洞处理方案和消除工程施工安全隐患提供了保障。
Geological radar on the underground geology and other unusual geological exploration results can effectively avoid the construction of the city subway on the surrounding environment and construction safety adverse effects. In this paper, the composition and measurement principle of GPR are introduced. Geological radar is used to detect the underground geology of some sections of urban subway construction. According to the detection results, the basic geographic information such as the location, depth and area of underground cavities are analyzed. Underground cavity handling programs and eliminate construction safety hazards provided.
