城市道路是城市基础设施的重要组成部分,但受到城市地下空间开挖利用的影响,城市道路路基常会出现如松动、脱空等隐患甚至引起路面坍塌,因此及时的发现并排除这些隐患是十分重要的。文章通过北京市某工程实例介绍了地质雷达的原理和在城市道路路基隐患探查中的应用。与传统方法相比,地质雷达具有迅速直观、准确全面等优点,是一种应用前景广阔的城市道路路基隐患探测手段。
Urban roads are an important part of urban infrastructure. However, affected by the excavation and utilization of urban underground space, the embankment of urban roadways often appear hidden, such as loosening and emptying, and even cause the road surface to collapse. Therefore, it is very important to discover and eliminate these hidden dangers in time of. The paper introduces the principle of GPR and its application in exploration of hidden dangers of urban roadbed through an engineering example in Beijing. Compared with the traditional methods, the GPR has the advantages of rapid and intuitive, accurate and comprehensive, it is a potential application prospect of urban roadbed hidden danger detection means.
