【摘要】 由废弃的地下采空区引起的地面沉陷，已成为一种典型的地质灾害，严重影响工程建设的顺利进行。为了采取相应的治理措施，查明地下采空区的埋深及分布范围显得十分重要。通过实例，简述探地雷达在探测地下采空区范围中的应用，探测目的在于确定地下采空区的深度、查明地下采空区的范围，为公路建设选线提供可靠依据。更多还原

【Abstract】 The land subsidence caused by abandoned underground mines has been a kind of typical geological disaster and influenced troublefree operation of engineering construction severely. In order to adopt homologues measure, it is important to explore the depth and distribution of underground pitting area .In this paper, the application of ground penetrating radar (GPR) in the exploration of underground pitting area is discussed by a successful example. The aim is to determine the depth and range of underground pitting area, and provide reliable information for highway line selection.更多还原
