岩石的摩擦是岩石力学的基本课题之一,自从Brace和Byerlee提出粘滑可能是浅源地震的一种重要机制以来,对于岩石摩擦现象的研究已引起更大的重视。作为岩石摩擦研究的第一步,我们在小型双剪设备上进行了房山大理岩的摩擦滑动试验。本文介绍并讨论试验的初步结果。 试验方法 试验使用的小型双剪设备如图1所示。两块尺寸为35×40×15毫米的大理岩,中间 Rock friction is one of the basic topics of rock mechanics. Since Brace and Byerlee proposed that stick-slip could be an important mechanism of shallow-earthquakes, more attention has been paid to the study of rock friction phenomena. As a first step in the study of rock friction, we carried out the frictional sliding test of Fangshan marble on a small double shear equipment. This article describes and discusses the preliminary results of the experiment. Test Method The small double shear equipment used in the test is shown in Figure 1.
