doi:10.12068/j.issn.1005-3026.2016.10.024

Abstract

Abstract: The rock joint normal tests of rock wall with different thickness were conducted without lateral confinements. Based on the test data， the relation between the stiffness and thickness of joint-rock wall system was analyzed， and the stiffness properties of joint-rock wall system with different thickness were obtained. The relations between the normal stiffness and closure of the joint under different confinement manners were analyzed， and a constitutive model for the normal deformation of rock joints with deformable rock walls was proposed. Furthermore， the structural and the material properties of the joint-rock wall system were discussed， and the test technique of the rock joint normal test was deemed important. This study will be helpful for understanding the rock joint normal deformation properties.

Key words: rock mechanics, rock joint, normal deformation, normal stiffness, deformable rock wall, constitutive model
