| 摘 要： | 本文根据页岩多级循环单轴压缩蠕变试验所得的数据,分析研究了加载历史对岩石试件变形的影响,提出了一种考虑这种影响的多级循环蠕变试验数据的整理方法。用该法整理出来的结果,比较真实地反映了岩石试件本身的流变力学行为,从而有助于建立岩石的本构方程。这种方法可供对粘弹塑性岩石进行多级循环蠕变试验时整理所得到的试验数据之用。

| Abstract: | Based on the data obtained from the various stepwise circular uniaxial compression creep tests of shale specimens,this paper makes researches and analyses on the influence of loading history on rock specimen eformation.Furthermore,on this basis,an experimental data processing method in consideration of this influence for various stepwise circular creep test is suggested.The results obtained from this method reflect more truly the intrinsic theological mechanical behaviours of rock specimen,thus tending to establish constitutive equation of rock.This
method might be used as a practical means for processing experimental data obtained by various stepwise circular creep test for various visco-elastoplastic rockes. |
