| Abstract: | Tunnel Zhuji No.1 on the Zhejiang-Jiangxi Railway Line is specified as an instance of tunnel collapse.The large-span shallow-depth unsymmetrically-loaded double-track tunnel under unfavourable geologic conditions is described in detail as to its collapsing process,collapsing causes and comprehensive measures to treat mountainous damages,tunnel failures and tunnel deformation and extend the length of the open-cut tunnel.Ground surface settlement and subsidence,fracture expansion,protective arch settlement,deformation segments,subsurface-excavation settlement and clear height variations are monitored. |
