我国大多数铁路隧道都建在山川河流之间,复杂的地质地貌增加了隧道施工难度,施工单位必须在施工前进行系统的地质勘探,并就复杂地质条件下施工所面临的各种突发问题提前制定应对策略。本文的研究对象是处于由软弱围岩构成的复杂地质条件下的沟里隧道工程,首先介绍软弱围岩地质条件的复杂程度,进而根据地质条件分析确定一套可行性工法和技术措施,再通过质量验收验证该工法的实效性。
Most railway tunnels in our country are built between rivers and rivers. The complex geology and landform increase the difficulty of tunnel construction. The construction unit must carry out systematic geological exploration before construction. In the light of various unexpected problems in construction under complex geological conditions Develop strategies in advance. The research object of this paper is the ditch tunnel project under the complicated geological conditions composed of weak surrounding rock. Firstly, the complexity of geological conditions of soft rock is introduced. Then a set of feasible methods and technical measures are determined according to geological conditions, Quality Acceptance Verify the effectiveness of the method.
