摘要
高温下岩石内部结构易发生破坏,渗流规律不再遵循达西定律。针对这一情况,从变形介质渗流理论入手,建立高温下岩石非线性渗流数学模型。该模型考虑了热压力梯度的作用,可为高温下的多场耦和问题研究提供理论基础。
This paper is aimed at addressing the failure of seepage rule to follow the Darcy flow due to the damages more likely to occur in internal structure of rocks exposed to a high temperature.The paper introduces the development of the mathematic model of rock nonlinear seepage flow under high temperature according to the deformation of the porous media.The model which allows for gradient effect of thermal pressure can provide theoretical basis for multiple field coupling under high temperature.
