Notes:
In this paper models are given for analysis and description of non-linear properties of joints, weak intercalations and interfaces in rock masses.Models for analysis consist of four parts, i.e. shear displacement model, normal deformation model, shear strength model and a relationship between unit shear stiffness and normal stress.The method of non-linear analysis given in this paper is based on an incremental procedure.The proposed method is available for different types of shear-displacement curves, and also adapted to the complicated process of loading-unloading-reloading.The results of computer simulation of an in-situ shear test obtained by this method gave a good fit to the measured data.The method of non-linear analysis of joint elements has been used in some practical rock engineering problems, and some interesting results and conclusions have been obtained.
