| 摘 要： | 隧道施工过程中,经常遇到突水、突泥和坍塌等无法预料的地质灾害,给施工安全带来了重大灾难和无法估计的经济损失,为了保证隧道施工安全,对不良地质体的发育情况进行准确及时的超前预报,是当前隧道设计与施工中亟待研究与解决的关键问题.详细介绍了TSP-203超前预测预报原理及方法,针对渝宜高速公路某隧道复杂的地质条件,在施工过程中进行了超前地质预测预报,并对预报结果进行了较为详细的处理和分析,同时根据隧道施工现场高压区富水层等地质情况,对隧道外水荷载计算方法和衬砌设计结构进行了分析.结果表明,预报成果与实际情况基本吻合,有效地指导了隧道施工.

| Abstract: | The unknown geological disasters such as rushing water, slurry and collapse often occur during construction of tunnels, which bring momentous disaster and unestimated economic loss to construction safety. The precise and immediate forecast to the development of bad geological bodies is the key problem to be researched and solved currently in tunnel design and construction, which has important theoretical significance and practical value. The principle and method of TSP-203 are introduced in detail. The paper cites the certain tunnel of the Yuyi highway, as an example, though the geologic term is complicated for abundant water in the tunnel, the advanced geologic prediction is adopted in the tunnel construction, and the external water pressure on lining and calculation model of line structure in the tunnel are analyzed, which are based on high pressure and rich water layer of the tunnel. The forecast results accord with practical situation, and guide effectively the tunnel construction safety. |
