The Ubiquitous-joint Model and Its Application in Predicting the Strength of Stratified Rock

摘要

Stratified rock mass has been widely existing in geotechnical engineering. Although many constitutive models have been adopted to describe the characteristic of the rock mass, like Mohr-Coulomb model and Hoek-Brown model, there are still few studies have been done on the constitutive model that can describe the stress-strain relationship of stratified rock mass. In the present paper, numerical solutions for prediction the strength of stratified rock mass is built, which is based on the Ubiquitous-Joint model for describing characteristic of stratified rock mass. Then its result is compared with that from the analytical solution based on Mohr-Coulomb model for validation.
