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。
By means of the model tests under the conditions of direct shear test, the deformation and strength characteristics of the shear planes containing both closed joints and rock bridges with different joint connection rates, joint arrangement and normal stress are studied, and the corresponding changes are also discussed The joints, rock bridge deformation and failure mechanism.
