| Abstract: | In this paper, the support mechanism of the different kinds of shotcrete lining over the surface of surrounding rock in circular tunnel and the influence of the rate of advance on the early strength of the shotcrete material are analyzed by means of a block-spring algorithm in which a new curve structure element is introduced. Some significant conclusions are drawn. |
