| 摘 要： | 节理的闭合性质主要取决于节理的组合形貌特征，而并不单独地取决于节理面各自的形貌特征。本文分析了节理面及节理组合形貌的形貌特征，提出了含波纹度节理的闭合模型，模型中采用了节理组合形貌参数，可反映接触状态和初始开度对节理闭合性质的影响。实验验证了该模型比不考虑波纹度的闭合模型更接近于试验结果。

| Abstract: | The closure behaviors of joint depend on the characteristics of composite morphology of joint principally and not morely depend on the morphologic characteristics of individual joint surfaces.In this paper after analysis of morphologic topographic characteristics of joint surfaces and composite morphology of joint a closure model for containing waviness in surface morphology is put forward.The composite morphology parameters of joint adapted in the model can reflect the influence of contact state and initial aperture on closure behavior of joint.It is confirmed by experiment that this closure model is closer to experiment results than the model that does consider the waviness in morphology of joint surfaces. |
