【摘要】 研究目的:高竹顶隧道F1断层是一条规模较大的断层带,在隧道施工开挖过程中可能会对围岩稳定产生较大的影响,故在隧道开挖过程中对其开展超前地质预报。研究结论:(1)TSP203 plus是长距离地质预报系统,预报距离一般在100～150 m之间;(2)TSP203 plus超前地质预报能够快速、准确地对预测段作出判断,对隧道施工方案和施工措施的选择,能够提供积极的指导性建议,具有显著的经济效益;(3)此次预报保证了隧道断层带的施工安全、加快了工程进度,同时为隧道超前地质预报的应用积累了一些经验。更多还原

【Abstract】 Research purposes:The fault F1 at the Gaozhuding Tunnel is a huge fault and it may produce some effects on stability of surrounding rocks during the tunnel construction,so it is necessary to conduct the accurate advanced prediction of the fault. Research conclusions:(1) TSP 203 plus is a long distance geological prediction system,and the distance is in 100~150 m;(2) Application of TSP 203 plus in the advanced geological prediction can rapidly and accurately judge the geological condition of the predicted area and it is crucial to choice of the construction scheme and measures of the tunnel,with the obvious economic benefits.(3) The application of the TSP 203 plus in geological prediction of the F1 fault for the Gaozhuding Tunnel guaranteed the construction safety and speeded up the construction process while the some experiences of the advanced geological prediction for tunnel were accumulated.更多还原
