摘要
采用变角板法进行室内剪切实验,探讨了锚杆加固节理裂隙试件的力学机理,同时结合数值模拟对锚杆控制节理裂隙边坡岩体的变形进行了分析。研究表明:锚杆加固不仅能提高节理裂隙岩体的整体性,而且在工程实际应用中能很好控制节理裂隙边坡的变形量。
The paper discusses the mechanics mechanism of bolt reinforcement for joint fissure test pieces with the method of variable angle plate indoor model experlment, and analyzes the deformation of anchor control joint fissure slope by combining with the numerical simulation. The resuhs show that the anchor reinforcement can not only improve the integrity of joint fissure rock mass, but also can well control the deformation of jointed slope.
