摘要
新建川藏铁路某长大深埋隧道,工程地质条件复杂,围岩分级,岩爆,大变形,涌突水,瓦斯,地温等主要工程地质问题对铁路选线及施工潜在影响极大。通过对某隧道隧址区地形地貌、地层岩性、地质构造等进行调查,简要分析了该深埋隧道工程主要地质问题围岩失稳、大变形、岩爆、涌突水、可溶岩、瓦斯及有害气体等(杨小军,2017)。针对该工程地质问题进行了简要分析评价。
The engineering geological conditions of a deeply buried long tunnel project of the proposed Sichuan-Tibet Railway are complex.Major engineering geological problems such as rock classification,rock burst,strong deformation,water gushing,gas and ground temperature has great influence on line selection and construction of the railway.This paper makes an approach to evaluation of the above-mentioned engineering geological problems.
