Abstract
The numerical model is established with ABAQUS numerical analysis software to analyze the mechanical characteristics of the tunnel lining and determine whether the fluid solid coupling is required, with a view to the rock breaking and heavy water gushing where Zeya tunnel passes through F10 a fault section. The seepage causes the tunnel lining stress to increase totally by 52. 15% and an increase of 75. 4% lining moment. Based on the great impact of water surge on tunnel mechanical property and the actual situation of tunnel surge water, the drainage hole with ring radial grouting is applied and ring grouting thickness and grouting material permeability coefficient are optimized by means of numerical analysis. The results show that the grouting layer thickness of 5~7 m and grouting material permeability coefficient of 30 ~ 50 times of surrounding will have a better construction result. The analysis results can be used to guide construction and provide reference for similar projects.关键词
