| 摘 要： | 本文对取自雅砻江锦屏二级电站的砂岩开展三轴压缩流变实验,并分析了实验数据,得到不同偏应力条件下砂岩轴向应变、侧向应变、轴向应变率和侧向应变率随时间的变化规律。并用Burgers体来反映瞬态蠕变阶段、稳态蠕变阶段的蠕变,进行了参数辨识,为工程围岩长期稳定性分析提供理论基础。

| Abstract: | Triaxial compression rheology tests for the sandstone from Jinping II Hydropower Station on Yalong River are conducted in this paper.Based on the recorded data,the change laws of axial strain,lateral strain,axial strain rate and lateral strain rate with time under different stress levels are obtained.Then,by using the Burgers constitutive model,the transient and steady creep of the sandstone can be reflected,and the related parameters are identified.This study may provide theoretical basis for analysis of l... |
