地铁施工前用地质雷达进行地下空洞探测的探讨与实践

随着城市建设的不断深入，地下隐伏空洞已成为城市的地质灾害。尤其是在地铁施工区域，空洞探测更显得迫切重要。本文结合工程实例，探讨了用地质雷达探测地下空洞，并找出地下空洞、土质疏松等病害的技术方案。

To Explore and Practice of Underground Cavity Detection by Using Geological Radar before Subway Construction

With the deepening of urban construction, the und-erground concealed void has become a city of geological dis-aster. Especial y in the subway construction area, the cavity de-tection is a more urgent mat er. This article bases on the project example to explore the use of geological radar to detect the un-derground cavity, and finds out the technical proposals of un-derground cavity, loose soil, and other diseases.
