摘要
对含结构面岩体的锚索锚固机理做了室内模拟实验研究,分别模拟了不同锚索安装角及不同结构面粗糙程度下锚索的抗剪特性;同时,为了更深入地研究锚索的受力情况,在锚索上布置了应变片,量测了不同加载阶段下锚索中钢绞线的受力状况。从实验结果来看,得到了一些有意义的结论。
Testing research is made in laboratory on anchoring mechanism of anchoring cable in jointed rockmass. The shear character of cable under different fixing angle and different roughness of joint plane is simulated in the test. At the same time,in order to furtherly investigate the loading mechanism of anchoring cable,some strain gauges are arranged on the different positions of cable,so that the strain of cable is obtained under different loading steps. The testing results provide some useful conclusions.
