路面塌陷是一种常见的路面病害现象,具有多方面的原因。地质雷达作为常用的物探方法,在路面塌陷探测分析中发挥着重要的作用。本文针对华苑科技园区内相邻道路的多起路面塌陷情况,采用地质雷达作为探测手段,通过对雷达剖面图的分析,准确的探测出地下塌陷的位置与分布,为养护维修管理提供依据。 Pavement collapse is a common phenomenon of pavement disease, for many reasons. As a common geophysical prospecting method, GPR plays an important role in the analysis of pavement collapse. In this paper, according to the situation of multiple road subsidence in adjacent roads in Huayuan Science and Technology Park, the use of GPR as detection means, through the analysis of radar profile, accurately detect the location and distribution of subsidence, provide the basis for maintenance and repair management.
