Research methods: In the course of the survey, many advanced technical means are adopted, including using remote sensing technology to indirect ground mapping work. The geological and hydrogeologic conditions of the area where tunnel passes through can be made clear through integrated geophysical prospecting along with the verification of hydrogeologic drilling and the parameters of geology , and hydrogeologic conditions can be obtained by testing the earth interior stress within drilled hole and integrated hydrology logging. The data for predicting volume of surging water of tunnel can be obtained by determining the flow of spring and the relations of supplement, route and drainage of underwater can be made clear by making sampling analyses of chemistry and tritium. The volume of surging water can be predicted by making calculation of hydrogeology.
Research results: Through making integrated survey, the lithology , geological structure and enriching water situation of strata in the area where the tunnel passes through can be made clear and the relative parameters of hydrageology can be obtained for providing basis for design and construction of tunnel.
Research conclusions: Through making survey of North Tianshan Mountain Summit Tunnel, the importance of application of many technical means together and the importance of hydrogeology in surveying deep buried large tunnel are recognized further and at the same time some problems are found
