【摘要】 随着隧道工程的数量和修建规模的不断增大,隧道施工时遇到的地质环境越来越复杂。隧道超前地质预报是复杂隧道施工中很重要的一个环节,有效的隧道超前地质预报是施工安全和工程顺利进行的有力保障。本文叙述的是云阳山隧道超前地质预报的研究内容。针对云阳山隧道的地质特点,采用了多种方法对云阳山隧道进行预报工作。本文地质预报工作主要介绍有以下几方面的内容：(1)结合前期勘查资料,分析了隧道的地质环境。以地质法为核心和基础,辅以钻探的方法,对隧道进行短期的预报。(2)研究了TSP和TGP在隧道预报工作中的应用情况,总结了这类方法的特点和使用经验。介绍了电测深法在预报工作中的应用情况。(3)对隧道地质灾害情况作了论述,制定了地质灾害可能分布情况图表。现场决策分析中,适当地运用了模糊综合评价法对围岩的破碎程度作出判别。超前地质预报为云阳山隧道成功修建提供了安全保障。云阳山隧道的地层以断层、破碎岩体为特征,地下水以基岩裂隙水为主,岩石的岩性和破碎规模控制着地下水的状况,TSP和TGP这类地震波反射法能发挥良好的作用。在采用钻爆法施工的隧道中,加深炮孔探测是一种很方便实用的方法。进行工程地质评价时,适当的运用模糊综合评价方法能起到较好的效果。更多还原

【Abstract】 Along with the number and scale of tunnel engeeringin creasing, geological environment encountered in tunnel construction ecomes more and more complex.Geological predication is an very important work in tunnel construction,which can provide guarantee for construction safety and project quality.The paper describes the research content of geological predication in Yunyang Mountain tunnel. According to the geological characteristics of Yunyang Mountain tunnel, several methods are used for the geological predication. The content of the paper generally involves the following aspects:(1) Analyze the geological environment in combination with previous investigation data.The short-term geological predication work is conducted on the basis of geologic method, supplemented by drilling.(2) Study the application of TSP and TGP, whose characteristics and application experience in geological predicationre are summarized. The application of electrical sounding method is also discussed in the paper.(3) Discuss the tunnel geological disasters and make the distribution charts of possible geological disasters. When making decisions on site, the broken degree of surrounding rock ahead the cutting face is judged by appropriately using fuzzy comprehensive evaluation method.Geological predication can provide security guarantee for the successful construction of Yunyang Moutains tunnel. The formation of the tunnel is characterized by fault and fracture zone, and the ground water is maily composed of bedrock fissure water. The condition of groundwater is also controlled by lithology and sale of fracture zone.The seismic wave reflection method, such as TSP and TGP, can play a good role in judging the rock of Yunyang Moutains tunnel. In the tunnel built with drill and blast method, the way of detecting by deepen blasthole is convenient and pratical. In the engineering geological assessment, the appropriate use of fuzzy comprehensive evaluation method could bring a good result.更多还原
