从分析断续节理岩体中岩桥的破坏模式出发,建立计算断续节理岩体极限强度的理论公式,定量地讨论了节理的排列方式及其力学性质对岩体强度各向异性的影响。通过试验验证,本文所建公式与试验值吻合较好。与前人研究成果比较,本公式具有适应性强,可靠度高的特点,可用于确定实际工程的节理岩体承载力并进行岩体稳定性评价
Based on the analysis of the failure mode of rock bridge in discontinuous jointed rock mass, a theoretical formula for calculating the ultimate strength of discontinuous jointed rock mass is established. The influence of the arrangement of joints and the mechanical properties on the anisotropy of rock mass is discussed quantitatively. Through experimental verification, the formula built in this paper is in good agreement with the experimental data. Compared with the previous research results, this formula has the characteristics of strong adaptability and high reliability, which can be used to determine the bearing capacity of rock mass and the stability of rock mass in practical engineering
