To examine the effects of the rockbolts,fitted with various angles and prestress levels,on the strength and tangent stiffness of discontinuities in a slope,an equivalent material simulation test of the slope with joints was caried out. The result shows that the effects are remarkable.

To examine the effects of the rockbolts,fitted with various angles and prestress levels,on the strength and tangent stiffness of discontinuities in a slope,an equivalent material simulation test of the slope with joints was caried out. The result shows that the effects are remarkable. According to the shear stress displacement response measured in the test,the strength and tangent stiffness of the joint were obviously enhanced after reinforcement,in another word,the response shows striking features of “plastic hardening”,and the response can be described as a hyperbolic function, Further study indicated that the main result of the enhancement of the shear strength is that the anchoring structure strengthened the equivalent cohesion of the joint, while the equivalent friction angle kept unchanged. At the end,the finite element simulation for the test was carried out,the result of FEA is consistent with that of the test fairly well.

为探讨锚杆在不同的安装角和预应力条件下对结构面强度和切向刚度的影响,进行了模拟实验研究·结果表明:锚杆安装角和预应力的大小对结构面强度和切向刚度有较大影响,加固结构面的剪切位移曲线具有明显的“塑性强化”性态,加锚后结构面的抗剪强度和切向刚度均有明显的提高,且加锚结构面抗剪强度的提高主要表现在结构面“等效粘结力”的提高,而结构面的“等效摩擦角”基本不变,加固结构面的剪切位移符合双曲线函数关系·最后对实验进行了有限元模拟,数值计算结果与实验结果具有较好的一致性

The influence of confining pressure on the post-peak softening rule of soft rock has been researched. Based on the stress-strain curve of triaxial experiments, the softening law of physical property parameters is studied; and a post-peak softening numerical model is established by means of the technique of determining the equivalent cohesion and friction and the curve-fitting. At last, the numerical simulation based on the model approximately matches the triaxial experiments.

根据三轴压缩试验的应力-应变曲线,运用Hoek提出的由主应力圆包络线确定粘聚力和内摩擦角等效值的方法和曲线拟合的方法,研究了围压对软岩峰后软化特性的影响和软岩的宏观物性参数峰后应变软化规律,建立了峰后应变软化数值模型。利用该数值模型对三轴试验进行数值模拟,其结果与试验数据吻合。
