摘要: 针对岩溶隧道单一超前预报方法预报结果与实际开挖揭露情况偏差较大的问题,提出采用隧道综合超前地质预报技术来提高对不良地质体预报的准确率,即采用宏观地质分析法、TSP地震波法、地质雷达法、掌子面围岩预判以及超前钻探相结合的方法,充分发挥各种预报方法的优势并进行相互补充和印证,提高不良地质体超前地质预报精度。 研究成果成功应用于利万高速谋道连接线齐岳山隧道的超前地质预报工作,避免了人员伤亡与财产损失。 以里程桩号GK0+708~GK0+720段范围内大型充水夹泥溶洞预报为例,详细阐述了综合超前地质预报的流程,并根据预报结果进行相应的处治措施,避免了溶洞塌方突泥等地质灾害的发生。 研究结果对类似岩溶地区的超前预报提供了参考和借鉴。

Abstract: According to the question that the results from the single advanced prediction method for karst tunnel prediction were different from the actual excavation, the integrated advanced geological prediction technology was proposed to improve the accuracy to unfavorable geologic bodies. Macroscopic geological analysis, TSP(tunnel seismic prediction)method, ground penetrating radar, observation of the tunnel face and the method of advance borehole drilling were combined in advanced geological prediction for tunnel. The integrated advanced geological prediction could give full play to the advantages of each prediction method and improve the accuracy. The research results were successfully applied on advanced geological prediction work in the Liwan highway Moudao Connecting Road Qiyueshan Tunnel. It avoided the casualties and property losses. The large karst cave filled with water and mud in front of the tunnel face of mileage GK0+708~GK0+720 was taken as an example. The process of the integrated advanced geological prediction was detailed and some effective measures were taken to avoid the collapse and the inrush of mud. The study can guide the advanced geological prediction of other similar karst regions.

Key words: macroscopic geological analysis, integrated advanced geological prediction, karst cave filled with water and mud, observation of the tunnel face, karst tunnel, Qiyueshan Tunnel
