摘要: 为分析评价地质环境对隧道工程建设的影响,通过对玉磨铁路新平隧道隧址区域的地形地貌、区域地质构造、地层岩性、水文地质及地应力等地质因素调查分析,运用层次分析法对隧道场址优劣等级进行风险评判。结果表明: 1)受隧址区地形地貌、地质构造、地层岩性、水文地质、地应力等地质因素影响和控制,隧道围岩整体表现为破碎、富水软弱,施工过程中极易诱发突泥涌水、坍塌、软岩大变形等不良地质灾害; 2)新平隧道隧址优劣等级综合评价值为1.31,场址优劣等级为极差,建设风险极高; 3)结合隧道施工实际揭露的围岩级别和发生的地质灾害情况,验证了隧址优劣等级评价方法及结果的准确性和可靠性。

Abstract: To analyze and evaluate the influence of the geological environment on the construction of tunnel engineering, investigation and analysis are conducted on the engineering geological conditions such as the topography and geomorphology, regional geological structure, stratum lithology, hydrogeology, and insitu stress of the tunnel site, and the analytic hierarchy process is used to evaluate the quality of the tunnel site. The research results show the following: (1) Affected and controlled by the geological factors such as topography, geological structure, stratum lithology, hydrogeology, and insitu stress in the tunnel site, the surrounding rock of the tunnel performs broken, waterrich, soft, and weak. Bad geological phenomena such as mud inrush, collapse, and large deformation of soft rock are easily occurred during construction process. (2) The comprehensive evaluation value of the Xinping tunnel sites superiority and inferiority grade is 1.31, and the sites superiority and inferiority grade is extremely poor, indicating extremelyhigh risk. (3) The reveled surrounding rock levels and geological disasters show the accuracy and reliability of the evaluation method and results of the tunnel sites superior and inferior grade.

Key words: railway tunnel, regional geological analysis, analytic hierarchy process, mud and water inrush, pros and cons grade evaluation
