一、引言岩石和岩体的本构关系(包括适用于可压缩流体的状态方程)是岩石介质的应力(或压力)、应变(或比容)、比内能(或温度)、及加载路径、应变率等之间的普遍关系式.它是研究应力波在岩石介质中的传播规律及其与地下结构相互作用的基础;在估价地下结构对各种爆炸作用的抵抗能力以设计经得起这些作用的防护结构时,在预报周围环境地运动及确定结构——介质相互作用时,都需要岩石和岩体介质的动力响应的精确描述;
I. INTRODUCTION The constitutive relations between rock and rock (including the equation of state applicable to compressible fluids) are the stress (or pressure), strain (or specific volume), specific internal energy (or temperature), and loading path of the rock medium, The general relationship between strain rates, etc. It is the basis for studying the propagation law of stress waves in rock media and their interaction with underground structures; the ability to resist the various explosion effects of underground structures is designed to withstand these. When the protective structure is in effect, accurate descriptions of the dynamic response of rocks and rock masses are required in the prediction of the movement of the surrounding environment and the determination of the structure-medium interaction.
