摘　　要：对隧道岩溶灾害研究 ,前人曾做过大量细致的工作 ,但由于问题的复杂性 ,论述多停留在灾害的一般定性描述 ,距解决实际问题尚有较大差距。本文将重点研究长大隧道岩溶涌水等灾害的预测预报技术。文中简要介绍了岩溶地区长大隧道岩溶水的特殊性 ,分析了隧道涌水涌泥及地表塌陷等灾害发生的规律。在此基础上提出以环境同位素技术、浅层反射波法、层析成像技术为主的结合化学动力学水文地质学理论的综合预测预报技术。Although a large quantities and careful works have been done and induced disasters in tunneling, karst areas, but there still are a large quantities problems needed to be solved ,due to the complicacy of such problems and the treatises are still remain at qualitative description of disasters. So the synthetic prediction technologies are going to be researched mainly for predicting waterinflow and induced disasters in tunneling, Karst areas. The specific characteristics of karst water in long and large Tunnel, karst areas will be briefly introduced, and the rules of waterinflow and induced disasters will be summarized in this paper. Finally, with the use of the hydrogeochemical model, the synthetic prediction technology will be advanced, mainly including environmental isotope, shallow earthquake reflection, computer tomography.
