| 摘 要： | 对层状盐岩力学特性进行实验与分析,获取相应的力学特征参数,是盐岩地下溶腔蠕变特性数值模拟的必要步骤,是数值计算中力学模型的组成要素。本文通过单轴压缩、三轴压缩和压缩蠕变等实验,获取层状盐岩短期强度特性和长期蠕变特性的力学特征参数,为盐岩蠕变模拟提供必要的参数支持。在此基础上,本文对层状盐岩蠕变机理进行分析,并将对盐岩蠕变率方程进行解析,为构建盐岩蠕变本构模型作铺垫。

Research on Mechanics Properties and Creep Mechanism of Layered Salt Rock |

| Abstract: | the mechanics properties of layered rock is tested and analyzed to obtain the corresponding mechanics characteristic parameters.This is the necessary step of numerical simulation of the creep properties of salt rock in underground cavity and the composing element of the mechanics model in numerical calculation.This essay,via the tests such as single-axis compression,three-axis compression,compression creep,etc.,obtains the mechanics characteristic parameters of the short-term intensity characteristics and long-term creep characteristics of layered salt rock to provide necessary parameter support to salt rock creep simulation.On the basis of this,this essay analyzes the creep mechanism of layered salt rock and parses the equation of salt rock creep rate to lay foundation for the construction of salt rock creep constitutive？model. |
