Closure deformation model for rock joints considering asperity interaction

摘要

摘要: 法向应力作用下节理的闭合变形是工程实践中常见但又未被很好解决的节理力学性质之一。依据弹性接触理论,提出考虑微凸体变形相互作用影响的闭合变形理论模型,该相互作用由一个均布荷载体现。模型采用不同接触下节理的组合形貌参数,适用于含起伏度分量的节理的闭合变形问题。较之于不考虑微凸体变形相互作用影响的Xia模型,新模型的计算值更为接近试验值。

Abstract: The load-closure behavior of rough surfaces remains to be an open question of interest with applications in many practical rock engineering problems. According to the elastic theory, a theoretical model is further developed for obtaining the stress-closure behavior of rock joints. The present model can account for the deformed asperity interaction expressed by a uniform pressure. The composite topography is used to capture the features of rock joints under different contacts and the corresponding topography parameters are the input parameters for validity of the proposed model. The new model is also suitable for solving the closure behavior of rock joints with waviness component. Compared with those by the Xia model, which ignores the asperity interaction, the calculated curves by the proposed model fit the experimental results well.
