摘要调查大光包滑坡滑带含脉状缺陷结构岩石碎裂特征，研究该类含缺陷岩石的循环加卸载破损机制，基于图像识别技术对试样中脉状缺陷面积进行统计，分别进行单轴压缩和加卸载试验。试验结果表明，缺陷结构界面易构成试样的潜在破坏面，加卸载应力处于弹性区间仍能明显造成该类试样损伤。同时，缺陷面积比对试样泊松比、损伤规律和峰值强度有较大影响，在加卸载作用下脉状缺陷面积比越大，相同加卸载次数时岩石泊松比越大，造成的损伤程度越高，岩石峰值强度降低越明显；脉状缺陷面积比越小，岩石泊松比越小，造成的损伤程度越低，岩石峰值强度降低有限。研究成果揭示了地震过程中缺陷结构和岩石非协调变形造成的累计损伤和强度劣化特征。

Abstract：To investigate fracturing characteristic and cycle loading and unloading damage mechanism of the rock with rein detects in the sliding zone of Daguangbao(DGB) landslide，the surface area of veins were counted based on the technology of image recognition，and uniaxial compression and unloading tests were carried. The test results show that the interfaces of the vein mass are easy to form the potential failure plane of the specimens，and that the loading and unloading stress in the elastic stage can obviously cause the damage of the specimen and reduce the strength of the rock. The area ratio of vein mass has a great influence on the Poisson?s ratio，damage rule and peak strength of the specimen. Under the same loading and unloading condition，the bigger the area ratio of vein mass，the greater the Poisson?s ratio and damage are and the lower the peak strength is. The smaller the area ratio of vein mass，the smaller the Poisson?s ratio and the damage of the rock are and the lower the peak strength. The results reveal that the stress concentration caused by the non-compatible deformation of the veins during the earthquake has a very obvious effect on the damage and strength degradation of the rock.

Key words： rock mechanics rock with vein defects loading and unloading rock damage strength degradation
