提出了一个基于测量锚固节理岩石位移的用以预测锚杆拉剪大变形行为的分析模型,给出了受拉剪荷载作用下的锚固节理岩石综合抗力的表达式,得到了考虑锚杆作用的锚固节理岩石剪切阻力与节理位移(或节理中锚杆变形角)间函数关系的理论全程曲线,试验验证了理论方法的有效性。
An analysis model based on the measurement of the rock displacement of the anchor joint is proposed to predict the large deformation behavior of the anchor. The expression of the comprehensive resistance of the rock under the tensile load is given, The theoretic full curve of the relationship between the shear resistance of rock and the joint displacement (or the deformation angle of the bolt in the joint) of the anchoring joint is validated by experiments.
