摘　　要：在地下岩体变形、地震的孕育与发生过程中,多种物理场、化学场是同时存在并相互影响的,其中应力场、渗流场和热场是其最重要的物理场。文中综述了近40年来地下岩体应力场-渗流场-热场三场耦合作用的研究现状,基于渗流场与热场、应力场与热场、以及三场耦合作用的研究,从场与场之间相互影响关系入手,综合分析了从以变量为媒介到以场为媒介,从松散耦合到强耦合,从观测统计模型到数值模拟的发展历程,并阐述了地下岩体三场耦合存在的问题和发展趋势。During the deformation of underground rock, and the gestation and occurrence of earthquakes, a variety of physical fields and chemical fields have interaction with each other. Among them the stress field, seepage field and thermal field is the most important physical field. The paper summarizes the development of the numerical simulation of the coupled stress field- seepage field-thermal field in the last 40 years. The paper firstly reviews the developments for coupled seepage field-thermal field, stress field -thermal field, and three fields coupling, and then based on the interaction of different fields, analyzes the research course of the coupled fields simulation from the variable as the medium to the field as the medium, from the loose coupling to the close coupling, from the numerical model to the operation simulation. Finally, The paper also discusses the existing problems and the development tendency of three fields coupling.
