The Durability Measures of the Lining of Newly Built Tunnels from Lining Disease of the Existing Tunnels
The 15 tunnels located in Line Chengkun, Baocheng and Dacheng were investigated by the authors. The tunnel disease was inducted and summarized, and the main disease forms and diseases reasons were analyzed.The five measures ( improve the compactness, control and reduce the initial crack, improve the toughness, reduce the second stiffness and mist curing) are proposed, and can improve the durability of the tunnel lining proved by large number indoor concrete test. The authors hope the results of this paper benefit design and construction.
