摘要
本文将损伤力学的原理引入岩体流变学的研究,建议了一个损伤演化方程以描述岩体力学性质随时间不断弱化的现象。系统地推导了有限元计算公式。地下巷道位移的实测验算表明,本文的本构模型是合理而有效的。
The Principle of damage mechanics is introduced into the researches of rock rheo- logy,and a damage evolution equation is proposed to describe the weakness of mech- anical properties of rock masses with time elapsing.The finite element formula are derived systematically.The checking computation result of in-situ monitoring data of a tunnel's deformation indicates that the model is reasonable and effective for thc numerical analysis of rock engineering.
