| 摘 要： | 为对隧道施工进行超前地质预报,在薛城隧道K30+708～K30+673段内右壁布设了24个激发孔,K30+728段左右壁各布设了1个接收孔,对出口段K30+652～K30+540段进行了测试,并利用TSP对测试数据进行处理、分析。根据围岩的实际开挖情况,由测定的纵波波速和岩体声波波速数据以及地震波的反射界面图,结合TSP的预报结果进行综合分析。结果表明,TSP技术在薛城隧道安全施工中的应用总体是可靠的。

| Abstract: | In order to perform geological prediction in section K30+708~K30+673 of Xuecheng tunnel for the construction of a tunnel,24 excitating holes were aranged on the right wall segment,and one receiving hole was arranged on right and left side of each wall in the section of K30+728.The exit of section K30+652~K30+540 was tested and the test data were processed and analyzed by using TSP.Comprehensive analysis of the prediction was conducted according to the actual excavation of rock,the measured longitudinal wave velocity and rock sonic velocity and seismic reflection data interface map,and combined with the TSP.Test results show that the application of TSP test technology in the safety construction of Xuecheng tunnel is feasible. |
