通过低应力水平下不同应变速率时循环加载次数对三城目安山岩的变形及其杨氏模量影响的实验研究 ,从循环加载次数对岩石变形特性影响这一角度探讨了低应力水平下三城目安山岩的粘弹性特性。结果发现 ,岩石这种天然材料自身具有明显的粘弹性特性 ,它所表现出的力学性质不仅与作用力的大小、方向、加载速率等密切相关 ,而且还与其作用力的方式和岩石自身的组构特征密切相关。
Through the experimental research on the deformation and the Young’s modulus of Mu’an Anamite under different stress rates at low strain level, the effect of cyclic load on the deformation characteristics of the rock is discussed. Viscoelastic properties of Mu’an rock. The results show that the rock itself has obvious viscoelastic properties. The mechanical properties of rock are closely related not only to the size, direction and loading rate of the force, but also to the mode of its force and its own group Structure characteristics are closely related.
