| Abstract: | Based on the scheme design for the intersection spanning between the new Zhongliangshan Tunnel of Chengdu-Chongqing Passenger Dedicated Line and the existing Zhongliangshan Tunnel of Xiangfan-Chongqing Railway,the article introduces the strengthening scheme of the intersection point systematically,including the strengthening measures for the secondary lining of the existing tunnel,the excavation supporting for the new one.Through the analysis and calculation on the structural strength by finite element method,the feasibility of strengthening scheme has been verified. |
