摘　　要：图云关隧道地质构造复杂,岩体破碎,施工中为减少和避免地质灾害发生,采用了TST超前预报技术。应用结果表明,TST技术采用空间观测系统有效地提高了速度分析精度和构造定位精度,成功地解决了围岩破碎带的超前预报问题。Geological structure of Tuyunguan Tunnel is complex, and rock is very fragmented. In order to avoid or decrease the geological hazard in construction, the advanced prediction technology of TST is adopted. The result shows that the spatial observation of TST can effectively improve the precision of the velocity analy- sis and structure location, and the technology of TST can successfully resolve the problem of advanced predic- tion in fractured zone.
