非贯通节理岩体抗剪强度影响因素分析
Analysis of Influence Factors on Shear Strength of Non-Penetration Jointed Rock Mass
摘要
Abstract
Based on the modified Lajtai rock bridge failure theory,the influence of connection rate,topo-graphic 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.关键词
