由于黑山铁路隧道中的混合岩、砂岩、砂岩夹泥岩、砾岩、砾岩夹泥岩受地质构造、高地应力和地下水的影响,岩体较破碎,局部地段岩体破碎,拱部围岩稳定性相对较差,围岩级别及支护措施调整较多。本文通过对黑山隧道工程工程地质、水文特征、地应力、岩体特征等情况的研究,分析围岩调整原因及施工措施并得出了相关的结论,为黑山隧道工程施工中遇到的主要地质问题提供了解决依据。
Because of the mixed rock, sandstone and sandstone mudstone, conglomerate and conglomerate mudstone in the Montenegro railway tunnel, the rock mass is fragmented, the rock mass is broken in some areas, and the stability of the surrounding rock in the arch area is affected by the geologic structure, the high ground stress and the groundwater Relatively poor, surrounding rock level and support measures to adjust more. Based on the study of engineering geology and hydrology characteristics, in-situ stress and rock mass characteristics of Montenegro tunnel project, this paper analyzes the reason of surrounding rock adjustment and construction measures and draws relevant conclusions. It is the main geology encountered in the construction of Montenegro tunnel project The problem provides the basis for the solution.
