中文摘要：

为解决岩质地基、边坡与地下岩体工程扰动与失稳、煤岩扰动与突出等实际问题,需要对岩体工程受扰动后的响应规律与特点进行深入研究。基于扰动状态概念理论,通过定义煤岩类准脆性岩石材料的相对完整状态、完全调整状态,从理论上给出了扰动函数公式,建立了煤岩类准脆性岩石扰动本构模型,并给出了模型参数解析式。通过煤岩和砂岩三轴压缩试验,所建本构模型与试验结果较为吻合,证明所建本构模型可以确定煤岩等准脆性岩石在扰动状态结构微调整过程中,任一状态下的扰动函数和应力-应变情况,为研究煤岩类准脆性工程材料受扰动后的力学特性提供了一种新的途径。

英文摘要：

In order to deal effectively with some practical problems, such as the disturbance and failure of rock foundation, slope and underground rock engineering, coal -rock disturbance and bursts etc. It is very necessary to study the response law and features of rock engineering after disturbance. Based on disturbed state concept （DSC） theory, an expression of disturbance function for the quasi - brittle rock materials as coal - rock was theoretically deduced through defining the relative intact state and fully adjusted state of quasi - brittle rock materials, a constitutive model reflecting the disturbance of quasi - brittle rock materials as coal - rock was established, and the analysis formulas of the parameters of the model were presented. The triaxial compression tests on coal - rock and sandstone were made, and it showed that the result obtained by the established constitutive model was in accordance with the one of the test, this proved that the established constitutive model can be used to identify the disturbance function and stress - strain of the quasi - brittle rock materials as coal - rock under any disturbance state in the process of structural micro - adjustment, thus it provides a new way to study the mechanical properties of disturbed quasi - brittle engineering materials as coal -rock.
