摘要
矿山岩体受力变形是在一定的时间和空间中发生。讨论其特性的流变力学模型主要有经验模型和组合模型两大类。近几年 ,出现了弹性 -粘塑性模型、滑移开裂模型、破裂间断波模型、突出流变机理学说及广义弹 -粘 -塑性模型等 ,有利于对岩石 (体 )材料力学性质的深入研究。
There are two kinds of models for the creep behavior of rocks for a long time: models by the experience, and models by the composition. A lot of new models have come now: Yamatomi's Model on the Relation of the Deformation with the time, Boukharov's Model by the principle of superposition, Qingming Ton's Model by the Fracture discontinue waves, etc. These models should be modified better because of the complex microscopic construction and the complex mechanical behavior of rocks.
