Abstract By applying the method of mechanics and combined with the construction situation of railway tunnels, the analysis on the loading situation of the structure of the formworked concrete lining in the single track railway tunnel with the surrounding rock of above IV class has been put forward, and the comparisons with the actual situation of cracks on the tunnel lining are put forward also in this paper. The courses of producing mi-cro-racks on tunnel lining are expounded, and the suggestions to avoid producing cracks are proposed.
