摘要:
为解决极端复杂地质条件下隧道TBM卡机受困的问题,本文以大瑞铁路高黎贡山隧道为例,根据隧道出口工区TBM已施工段卡机里程统计,以及地表物探、深孔钻探成果预测的高风险卡机段落统计情况,采用分项对比分析及综合成果对比分析的方法,总结出综合成果耦合性分析结论,提出TBM法施工隧道工程地质勘察建议,结果表明:(1)地表物探、深孔钻探预测成果与实际卡机里程耦合率均为50%,耦合率较低;(2)综合物探及钻探成果后,预测卡机高风险段落为12段,与实际卡机里程耦合率增加至71%;(3)采用地质深孔钻探对地表物探法进行验证,并利用两种勘察方法成果进行综合分析评价,可有效地增加TBM卡机受困风险段落预测的准确性。本文研究成果可为TBM后续施工提供一定的指导意义。
Abstract:
The purpose of this paper is to solve the problem of TBM jamming in tunnels under extremely complex geological conditions. Based on the case study of the Gaoligongshan Tunnel of the Dali-Ruli Railway, this paper provides an itemized comparison and a comprehensive comparison of the statistical results of TBM jamming chainage in the constructed section of the tunnel exit area and the statistical results of the high-risk jamming section predicted by surface geophysical prospecting and deep borehole drilling results, summarizes the conclusions of the coupling analysis of the comprehensive results, and proposes recommendations for the engineering geological investigation of the tunnel constructed by the TBM method. The results show that: (1) The coupling rate between the predicted results of surface geophysical prospecting and deep hole drilling and the actual jamming chainage are all 50%, which is a low coupling rate. (2) After integrating the results of geophysical prospecting and drilling, the number of the predicted high-risk sections for jamming is 12, and the coupling rate with the actual jamming chainage increases to 71%. (3) The use of geological deep-hole drilling to verify the surface geophysical prospecting, and the use of the results of the two survey methods for comprehensive analysis and evaluation, can effectively increase the accuracy of the prediction of the sections with TBM jamming risk. The research results in this paper can provide guidance to some extent for the subsequent construction of TBM.
