Crack Propagation Detection and Simulation Research of Jiulong Tunnel

Abstract:

According to the specific engineering examples, the detailed analysis of the lining crack damage in process, status, characteristics and the distribution of disposal has been done. Based on the exploration and analysis of construction process and topography and geology factors , this paper discusses the genesis of lining crack , establishes the numerical model in lining cracks section taking the real topography condition, structure parameters of surrounding rock, the actual construction sequence,etc. Focus on the principal stress distribution law in lining structure and collapse deformation of surrounding rock, this paper explaines the cracks mechanism in theory, and the results is consistent to the actual practice.
