【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]:In view of the problem that the prediction results of single advance prediction method for karst tunnels deviate greatly from the actual excavations, a comprehensive advanced geological prediction technique is proposed to improve the accuracy of forecasting bad geological bodies. That is to say, using the methods of macroscopic geological analysis method, tsp seismic wave method, geological radar method, forejudgment of face surrounding rock and advanced drilling, the advantages of various forecasting methods are fully brought into play and each other is supplemented and verified. Improve the accuracy of advanced geological prediction of poor geological bodies. The research results have been successfully applied to the advance geological prediction of Qiyueshan Tunnel, the link line of Liwan Expressway, and the casualties and property losses have been avoided. Taking the prediction of large water-filled mud-filled karst cave in the range of mileage pile number GK0 708~GK0 720 as an example, this paper expounds in detail the process of comprehensive advanced geological prediction, and carries out corresponding treatment measures according to the forecast results, thus avoiding the occurrence of geological disasters such as cave-collapse mud and so on. The results provide a reference for the prediction of similar karst areas.
