摘要

长大深埋隧道断层带地质灾害的综合超前地质预报少有体系完整的应用范例,以汶马高速控制性工程鹧鸪山隧道为例,以地质分析为核心,综合物探与地质分析相结合,洞内外结合,长短距离预测结合,多物性参数互补,完成了一套完整的综合超前地质预报体系在长大深埋隧道断层带的应用。通过实际开挖,证明了预报的准确性,协助施工方及时控制掘进进度,一定程度上降低了一次塌方的突发性。鹧鸪山案例具有良好的典型性,全程的方法可操作性强,可借鉴性强,可供钻爆法施工环境类似工程参考。
        There is few systematic and complete application example of comprehensive geological prediction of geological hazards in deep buried tunnels. The Zhegushan Tunnel of the high-speed control project in Wenma was taken as an example. Taking geological analysis as the core, the application of a complete comprehensive advanced geological prediction system in the fault zone of the long and deep buried tunnel was completed with the combination of integrated geophysical exploration and geological analysis, the combination of internal and external caves, long-short distance prediction combined and multi-physical parameters complementary. The actual excavation proved the accuracy of the forecast, and helped to control the tunneling progress in time, which reduced the impact of landslides. As the instruments are commonly used in advanced prediction work, the whole method in Zhegushan case can be transplanted to similar projects.
