摘要
Abstract
In order to discuss the excavation of tunnel entrance through fault fracture zone,the application of three-step temporary invert method in tunnel excavation through fault fracture zone was analyzed based on Lizhou Hydropower Station project.The analysis shows that the geological conditions of the hole body in the fault fracture zone are complicated,the stability of surrounding rock is relatively poor,and the probability of collapse is relatively large.The construction method of using the temporary invert method with the combination of system anchor rod,steel mesh,steel frame and wet shotcrete can not only ensure the construction efficiency,but also effectively control the collapse problem.The construction task can be completed efficiently,safely and orderly,which can provide reference for similar engineering construction.关键词
