本文介绍了流体力学剪切试验的一些试验结果和巴顿（核废料隔离办公室，俄亥俄州，哥伦布，ONWI-308，1982）提出的原始模型的改进版本。96pp.）岩石节理的流体力学耦合。原始模型是针对正常加载和卸载过程中机械和水力孔径变化之间的耦合而开发的。提出了剪切剪胀与水力孔径变化耦合的方法。改进后的模型具有与原模型相同的外观，并基于花岗岩岩石节理的流体力学剪切实验。它包括机械和水力孔径以及可动节理粗糙度系数（JRC（mob））。(C)2001爱思唯尔科技有限公司版权所有。
This paper presents some experimental results from hydromechanical shear tests and an improved version of the original model suggested by Barton (Office of Nuclear Waste Isolation, Columbus, Ohio, ONWI-308, 1982. 96pp.) for the hydromechanical coupling of rock joints. The original model was developed for coupling between mechanical and hydraulic aperture change during normal loading and unloading. The method was also suggested for the coupling of shear dilation and hydraulic aperture changes. The improved model has the same appearance as the original and is based on hydromechanical shear experiments on granite rock joints. It includes both the mechanical and hydraulic aperture and the mobilised joint roughness coefficient (JRC(mob)). (C) 2001 Elsevier Science Ltd. All rights reserved.
