AFFECTING PRINCIPLE OF THE SELF SUPPORTING ROCK RING AROUND TUNNELS AND ITS BE ANALYSIS

    摘要
  • 摘要: 本文分析了地下工程围岩中自承岩环的形成及作用原理,用边界单元法计算了侧压力系数分別为λ=1,2时的圆及拱形洞室在切缝弱化以后的应力分布。结果表明用自承岩环代替衬彻支护是可能的。

     

    Abstract: The forming and affecting principle of the self supporting rock ring around tunnels is analysed in this paper. After slotting in surrounding rock of the circular and arch tunnel, the stress distribution is computed by BEM. The results indicate that it is possible to use the self supporting rock ring instead of the lining support.
