| 摘 要： | 对节理岩体等效损伤流变模型进行了初步研究,假设岩石为各向同性体各向同性损伤,节理面的法向和切向损伤不同,分别建立了岩石和节理面流变损伤演变函数。假设材料无损,计算应力采用有效应力,推导了节理岩体等效损伤流变模型有限元计算公式,编制了相应的有限元程序。算例分析表明,采用的节理岩体等效损伤流变模型是可行的,可较好地反映节理岩体的损伤演变过程。

| Abstract: | Equivalent damage rheological model for jointed rock is preliminarily studied.Rock and jointed plane's damage rheological functions are developed separately on the basis of supposing that the rock is isotropic body and isotropic damage and the jointed plane's normal and tangential damage is different.Finite element method calculation function of equivalent damage rheological model for jointed rock is deduced;and its finite element method program is developed by assuming that the material is not damage and c... |
