| Abstract: | By combining with the tunnel construction examples along some railway,the paper analyzes reasons for the shifting sand in tunnels and the collapse forms,makes some reasonable and effective construction measures,sums up some construction points,and guarantees the safety and the smoothness of the construction by adopting some measures,including advanced support,the early lining,the sealing ring closure. |
