基于扩展有限元的隧道衬砌裂缝开裂数值分析
Numerical analysis of cracking of tunnel linings based on extended finite element
摘要
Abstract
Through the inspection of 48 tunnels in Zhejiang Province and the statistical analysis of numerous cases of lining cracks, the distribution laws and main influencing factors of lining cracks are attained. The applicability of XEFM for lining cracking is proved by the comparison between the numerical analysis and the prototype test. The propagation and distribution laws, appearances and cracking mechanism of cracks under main influencing factors are studied by using XEFM. This research provides reference for deciding the reasons of lining cracks and lay foundation for preventing and repairing lining cracks.关键词
