摘要
一、引言 关于表面粗糙的无充填结构面的抗剪强度特性研究,最早的成果是由Patton(1966)提出来的,他用一系列带规则突起的模型所作的一系列试验证实,这类结构面的剪应力(τ)和法向应力(σ)之间具有如下关系:
In this paper, two methods——frequency spe-ctrum analysis and 'data wave-filtering' are ado-pted to make a quantitative study to undulationsof discontinuities not to be filled. A modifiledrelationship between the undulations and JRC (thejoint roughness coefficient) in Barton's shear stre-ngth criterion is put forward, which is expressedquantitatively by the amplitude of joint undulationsand formulars imitating the complicated Barton'sroughness curves.
