| Popis: | In the previous paper, the authors proposed the design formula which was based on the distortional strain energy stored at each stage of tunnelling. In this paper, the side pressure coefficient k and elastic constant ER of ground are firstly studied with the displacement data obtained by the tunnel measurement in the past, and then the applicability of the proposed design formula, the efficiency of tunnel support and the safety factor of actual tunnels are discussed. The preliminary design method of tunnel is also presented. |
