摘要
考虑岩体介质是由基质岩块与裂缝组成的结构体,采用岩体结构力学的研究方法,针对岩石矿物组分及其分布的不同,将物理力学参数作为随机介质,建立了岩体介质的三维随机非均质固流热耦合数学模型,介绍了随机有限元计算方法,深入分析了随机固流热耦合模型的特点,该模型是经典固流热耦合数学模型的扩展,为岩石热破裂数值实验的研究提供了理论基础及其方法。
Considering rock mass is structure of made rock matrix and fracture,with research method of rock structure mechanics,based on the differences of micro-structure and random distribution of rock,the physice mechanical properties’ random non-homogeneity,the paper presents 3-D random non-homogeneous solid-flow-heat coupled mathematics model and FEM,analyzing carefully features of random non-homogeneous solid-flow-heat coupled mathematics mode. This model is development of homogeneous the solid-flow-heat coupled mathematics mode,this paper offers the foundation and methods for the study of rock hot cracking.
