本文介绍一种综合模型,用以模拟采用全长粘结被动岩石锚杆加固节理岩体的性状。该模型基于“等效材料”方法。在这种方法中,岩石节理和岩石锚杆的影响和作用遍及整个岩体。文中用有限元法分析了一个节理岩石边坡的典型问题,并计算出其抗破坏的安全因子。在确定被动的全长粘结岩石锚杆的有效性时,岩石节理的膨胀性和岩石锚杆的方位是最为重要的影响因素。
This article describes a comprehensive model to simulate the behavior of jointed rock mass reinforced with full-length bonded passive rock bolts. The model is based on the “equivalent material” method. In this method, the effects and effects of rock joints and rock bolts throughout the rock mass. In this paper, the finite element method is used to analyze the typical problems of a jointed rock slope, and its safety factor against damage is calculated. In determining the effectiveness of passive full-length bonded rock bolts, the expansion of rock joints and the orientation of rock bolts are the most important factors.
