地质雷达在地铁隧道超前地质预报中的应用

The application of geological radar in advanced geological forecast of subway tunnel

以某地铁隧道超前地质预报为工程实例,应用地质雷达技术,在分析了地质雷达工作原理的基础上,结合前期勘察和施工现场情况,对掌子面前方的破碎带和含水层进行了准确预报,验证了地质雷达预报的准确性,并根据地质雷达的原理,对其应用的优缺点给出了建议。

Taking the advanced geological forecast of subway tunnel as an example, this paper applied geological radar technology, based on a nalysis on the working principle of geological radar, combining with the previous investigation and construction site conditions, made accurately forecast to fracture zone and aquifer front of tunnel face, verified the accuracy of geological radar forecast, and according to the principle of geo logical radar, gave commendations to the advantages and disadvantages of its application.
