摘要
通过直剪试验条件下的模型试验，研究了不同节理连通率、节理排列方式、正应力条件下同时包含闭合节理和岩桥的剪切面的变形和强度特性及其相应的变化规律，初步探讨了节理、岩桥变形和破坏机理。
In this paper, through the m odel tests under direct shear condition, the deform ation andstrength behaviour and their corresponding varying law ofrock containing close joints and rock bridge under 7regim es w ith different com binations of joint continuity, joint arranging m odes and norm alstress are studied. The deform ation and failure m echanism of joint and rock bridge are discussed.
