摘要:
基于修正的Lajtai岩桥破坏理论,研究连通率、形貌节理起伏角、法向压力等因素对非贯通节理岩体抗剪强度的影响,利用人工混凝土模拟类岩石材料,并进行直剪实验论证.结果表明:非贯通节理岩体抗剪强度与起伏角大小成正相关关系,与连通率成负相关关系;其他影响因素相同时,法向压力越大,非贯通节理岩体抗剪强度越大.
Abstract:
Based on the modified Lajtai rock bridge failure theory, the influence of connection rate, topographic joint undulation angle, normal pressure et al. on shear strength of non-penetration jointed rock mass is studied. Using artificial concrete to simulate the rock, the direct shear experiment is conducted. The result shows that: the shear strength of non-penetration jointed rock mass is positively correlated with the undulation angle, but is negatively correlated with the connection rate; under the same other factors, the normal pressure is positively correlated with the shear strength of non-penetration jointed rock mass.
