This book is a monograph on the study of the deformation characteristics and strength characteristics of jointed rock masses under three-dimensional in-situ stress environments. The book takes the complex high stress environment in actual engineering as the research background, takes jointed rock mass as the research object, and based on the similarity principle of model testing, conducts true triaxial model test research based on similar materials, and studies the joint connectivity of jointed rock mass under a three-dimensional stress environment. Rate, the number of joints, the angle between the number of joint groups, the spatial combination relationship between rock mass joints and three-dimensional stress, etc., On the deformation characteristics and strength characteristics of jointed rock mass; based on this, the rock mass strength criterion was revised and the strength deformation mechanism of jointed rock mass was discussed.
