摘要： 开展了无周边约束条件下不同岩壁厚度结构面法向变形试验，结合结构面-岩壁系统刚度与系统厚度之间关系，得到了不同岩壁厚度条件下结构面-岩壁系统整体刚度的变化特征，以及岩体结构面刚度与结构面厚度.分析了不同周边约束条件下结构面刚度与闭合量之间的关系，提出了考虑岩壁变形条件下结构面法向变形本构模型及其适用条件.进一步讨论了岩壁-结构面系统的结构和材料特征，分析了结构面法向刚度合理试验方法的重要性.本研究将有利于加深对结构面法向变形特征的理解与认识.

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
