摘要: 诸多岩石工程都涉及高温岩石问题,开展高温下岩石的本构关系尤为必要.基于扰动状态概念理论,通过定义与温度相关的扰动函数,建立起高温岩石的扰动状态本构模型.利用高温下实施的花岗岩单轴压缩破坏试验,对建立的本构模型进行了检验.研究表明,所建立的本构模型能描述高温岩石的力学响应特性.

关键词: 高温, 岩石, 扰动状态概念, 本构模型

Abstract: It is necessary to carry out the constitutive relation of rock under high temperature because a lot of rock engineering involves the problem of high temperature rock. In this paper, based on the theory of disturbed state concept, a disturbed state constitutive model of high temperature rock is established by defining the temperature dependent disturbance function. The constitutive model is verified by the uniaxial compressive failure test of granite under high temperature. The study shows that the established constitutive model can describe the mechanical response characteristics of high temperature rock.

Key words: high temperature, rock, disturbed state concept (DSC), constitution model
