摘要
将一种新的曲线结构单元引入到块体一弹簧算法中，对圆形断面隧道围岩表面喷射不同混凝土衬砌的支护作用机理以及开挖速度对喷射混凝上材料早期强度的影响等进行分析，得出了一些有意义的结论。
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.
