    摘要:

    基于弹性地基梁建立了隧道衬砌的控制微分方程,根据圣维南原理推出裂缝间距相应中心角应满足的卓越方程,由此求出了隧道衬砌在荷载作用下产生的裂缝间距,进而确定相同裂缝间距和不同裂缝间距情况下的裂缝宽度。

    Abstract:

    Based on the elastic foundation beam,the control differential equation of tunnel lining is worked out,according to the theory of Saint-Venant,the predominance equation about the center angle to the crack space is established, then the crack space of tunnel lining under the loads can be worked out and according to the crack space,the crack width can be calculated.
