SUN Hai-tao~(1,3),DING De-xin~2,LIU Dong-yan~1,YANG Ting-ba~4(1.College of Civil Engineering,Chongqing University,Chongqing 400045,P.R.China;2.School of Architecture & Sources Engineering,Nanhua University,Hengyang 421001,P.R.China;3.The Subsidiary Department of the Coal Scientific Research Institute,Chongqing 400037,P.R.China;4.The Fifth Department of Chinese Railway Tunnel Group Company,Lechang 512200, P.R.China)  
The construction uime of the shotcrete lining in the tunnel construction,currently,used to be determined by the experience with poor reasonability and feasibility.In this paper,by connecting the numerical method and the construction measurement,the author suggested the method for determining the construction time for shortcrete lining with the displacement of measured point in the tunnel before the lining construction and this method was firstly applied in the construction analysis of the "Mawangcao" tunnel.The result indicated that this method was effective in the analysis and comparison of the tunnel construction project
