研究目的:本文根据作者在北天山越岭隧道的工作经历，对北天山越岭隧道调绘和勘察全过程进行了总 结，并阐述了自己的亲身体会，对工作中出现的一些问题提出了自己的一些看法。
研究方法:在越岭隧道的勘察过程中，广泛采用了先进有效的技术手段，以遥感技术指导地面的调绘工 作，通过综合物探，配合适量的钻探验证，以查明隧道通过区的地质及水文地质条件，通过钻孔内的地应力测 试及综合水文测井，并取得相应的地质及水文地质参数;通过对泉水流量的测定，为隧道涌水量的预测提供了 依据，并通过取样进行化学分析及氚分析，查明了地下水的补、径、排关系;通过水文地质计算，预测隧道的涌 水量。
研究结果:经过综合勘察，查明了隧道通过区的地层岩性、地质构造及地层的富水情况，取得了相应的水 文地质参数，为隧道的设计及施工提供了依据。
研究结论:通过对北天山越岭隧道的勘察，进一步认识了多种技术手段相结合的必要性，也充分意识到了 水文地质工作在深埋长大隧道勘察中的重要性。但同时在工作中也发现了一些问题，通过经验总结提高了 认识。
Research purposes :Based on the author's working experiences of construction of North Tianshan Mountain Summit Tunnel , the summary is made for the entire progresses of mapping and survey and the views are presented on the problems existed in the work.
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
