隧道地质雷达超前地质预报技术应用研究——以斋堂隧道工程为例

Research on Application of Advanced Geological Prediction Technology of Ground Penetrating Radar in Tunnels——Taking Zhaitang Tunnel Engineering as an Example

随着工程建设步伐的逐渐加快,隧道数量也不断增加,为安全有效地指导隧道开挖,使隧道施工技术越来越信息化、科技化,在隧道掌子面开挖前进行超前地质预报是极其重要的步骤。文章主要采用拉脱维亚地质雷达对国道109新线高速公路中的斋堂隧道工程进行超前地质预报,为隧道施工支护提供技术依据,确保施工措施合理,指导隧道安全施工,降低施工风险。

With the gradual acceleration of the pace of engineering construction, the number of tunnels is also increasing. In order to safely and effectively guide tunnel excavation and make tunnel construction technology more and more informatized and technological, it is an extremely important step to carry out advanced geological prediction before tunnel face excavation. This paper mainly uses Latvian ground penetrating radar to carry out advanced geological prediction in Zhaitang tunnel engineering of national highway 109 new expressway, which provides technical basis for tunnel construction support, ensures reasonable construction measures,guides safe tunnel construction and reduces construction risk.
