摘要

对金坛盐岩蠕变规律进行了试验研究

分析了不同应力状态和温度对盐岩蠕变特性的影响

通过试验获取了蠕变曲线和蠕变特征参数。根据其蠕变曲线特征

用黏弹塑性理论建立了盐岩蠕变本构模型。试验结果表明

稳态蠕变率是偏应力和温度的非线性函数关系

并提出盐岩的稳态蠕变本构方程。通过试验数据拟合得到本构方程中的参数

将理论和试验结果进行比较

结果表明两者的吻合性较好。

Abstract

Uniaxial and triaxial creep tests have been performed on rock salt of Jintan Salt Mine on high temperature and high pressure triaxial rheological device;the creep characteristics of rock salt are investigated and the effect of stress state and temperature of rock salt are analyzed;and then the creep characteristic curve and parameters are obtained.Based on the character of creep curve of rock salt

a creep constitutive model of rock salt is established by using viscoelasto-plastic theory.Through the test results

it is shown that the steady state creep strain rate is a nonlinear function of diviatoric stress and temperature;a steady state creep constitutive model of rock salt is established.The patameters of constitutive equation are obtained by fitting test data;the theoretic results is proved well by comparison with the experimental results.
