岩石在不同温度下的形变蠕变和滞后

据岩石在地壳温度条件下的实验结果:只要循环加载,应力与应变便无单值关系。因为现代构造应力场是在时增时减地变化着,所以定点长期连续观测的地应力台站,不能根据地应变值来换算地应力,而需通过弹性选测法和应力平衡法来确定

ABOUT THE DEFORMATION, CREEP AND HYSTERESIS IN ROCKS AT VARIOUS TEMPERATURES

The experimental results on rocks at a temperature equal to the earth's crust indicate that as long as a cyclic load is applied on rocks, there no monodromic correlation would be appeared between stress and strain. Thus the recent tectonic stress and strain fields are changing, now extensively, now weakly. For this reason, there is impossible for the earth stress stations for long-term continuous observation at the fixed points to evaluate the earth stress by the strain, thus a selective method
