高风险隧道施工期水害预报方法研究

Study on Prediction Methods of Water Damage in High Risk Tunnel Construction

隧道水害在隧道施工期普遍存在,尤其在岩溶地区,隧道施工中80%遇到水害,隧道水害给施工安全带来了重大灾难和无法估计的经济损失。主要介绍了目前国内外对于高风险隧道施工期水害探测的方法:水文地质法、地质雷达技术、瞬变电磁法、红外探水法等。并对每种方法进行了现场工程应用,对高风险隧道施工期水害超前预报及施工安全具有一定的理论价值和工程实用价值。

Water damage is frequent in tunnel construction, especially in the karst region, about 80%of all constructing tunnels are faced of water hazard, which lead to major disasters and unestimated economic losses. In this paper, several prediction methods of water damage in high risk tunnel construction are introduced, for example hydrogeological method, GPR technology, transient electromagnetic method and infra-water method, and so on. And all the methods mentioned above have been applied, which has theoretical value and practical engineering value to prediction methods of water damage in high risk tunnel construction and construction safety.
