摘要
为解决成兰铁路跃龙门隧道工程建设难题,对活动断裂、岩溶涌水、有害气体、大变形、高地温等重大工程问题的形成背景、成因机制、特征规律及防治对策开展深入研究。结果表明,跃龙门隧道所在的西部复杂强震山区地质区域性特征显著,应加深区域地质研究测试工作;在活动断裂区施工时应开展洞身核查,明确断裂性质及两盘改造的差异性;解决复杂地质问题应加强区域地质演化分析,划分地质环境单元,形成区域工程地质理念。
In order to solve the construction problems of the Yuelongmen Tunnel on the Chengdu-Lanzhou Railway,in-depth research is carried out in terms of formation background,cause mechanism,characteristic laws and prevention countermeasures of major engineering problems such as active fault,karst water inflow,harmful gases,large deformation and high ground temperature.The results show that the regional geological characteristics of the complex western mountainous area with strong earthquakes,where the Yuelongmen Tunnel is located,are remarkable,and the regional geological research and test effort should be strengthened.During construction in active fault areas,tunnel body should be verified to understand the nature of the fault and the differences between the renovations of hanging wall and footwall.To solve complex geological problems,it is necessary to strengthen regional geological evolution analysis,divide geological environmental units,and form a regional engineering geological concept.
