摘要
通过规则齿形结构面在双轴应力条件下的蠕变试验,对规则齿形结构面剪切蠕变特性进行了深入的研究,分析了规则齿形结构面蠕变的基本规律。在分析对比的基础上选取Burgers模型作为研究的重点来反映岩体的蠕 变特性,通过数值分析计算出模型参数,模型曲线和试验数据得到了很好的拟合。
Testing study is made on the creep characteristic of regularly dentate discontinuity in the condition of two-axial stresses,and the normal creep rule of regularly dentate discontinuity is analyzed. Burgers model is selected to reflect the creep characteristic of discontinuity. The model parameters are figured out by numerical analysis and the model curve is in good agreement with test dada.
