Study on the Constitutive Model for Jointed Rock Mass
A new elasto-plastic constitutive model for jointed rock mass, which can consider the persistence ratio in different visual angle and anisotropic increase of plastic strain, is proposed. The proposed the yield strength criterion, which is anisotropic, is not only related to friction angle and cohesion of jointed rock masses at the visual angle but also related to the intersection angle between ...
متن کاملMicroplane damage model for jointed rock masses
The paper presents a new microplane constitutive model for the inelastic behavior of jointed rock masses that takes into account the mechanical behavior and geometric characteristics of cracks and joints. The basic idea is that the microplane modeling of rock masses under general triaxial loading, including compression, requires the isotropic rock matrix and the joints to be considered as two d...
متن کاملConstitutive Modeling of a Jointed Silica Lime Rock
ABSTRACT: A number of civil engineering projects which include river valley projects, transportation projects and metro rail projects are under construction in India. Various structures, such as underground openings, powerhouse caverns, metro tunnels, dam foundations and slopes are increasingly located in/on rock formations. The rock in its natural state is a very complex material especially wh...
متن کاملA Nonlinear Creep-damage Constitutive Model of Mudstone Based on the Fractional Calculus Theory
During the flood development in an oil field, the creep characteristic of mudstone is one of the important factors causing casing damage. In this study, based on the theory of fractional order differential and taking into account the creep damage evolution rules, a fractional nonlinear creep-damage model is proposed to reflect the instantaneous deformation in loading processes and the accelerat...
متن کاملA Model of Anisotropic Property of Seepage and Stress for Jointed Rock Mass
Joints often have important effects on seepage and elastic properties of jointed rock mass and therefore on the rock slope stability. In the present paper, a model for discrete jointed network is established using contact-freemeasurement technique and geometrical statistic method. A coupled mathematical model for characterizing anisotropic permeability tensor and stress tensor was presented and...
