一种减少岩石裂隙剪切渗流实验中端部摩擦效应的装置
摘要：
本发明属于岩石力学技术领域，提供了一种减少岩石裂隙剪切渗流实验中端部摩擦效应的装置，包括用于剪切裂隙岩石试样的剪切装置、控制流体流动的渗流装置、减少摩擦的装置及密封装置。本发明的装置除了用于剪切裂隙岩石试样的剪切装置和控制流体流动的渗流装置之外增加了减少摩擦的装置，所述剪切装置包括法向加压板、底座、上垫块以及下垫块。裂隙岩石试样放置于上下垫块之间，上垫块连接法向加压板，下垫块连接底座。所述减少摩擦的装置包括用于减少上垫块与试样之间的上部减少摩擦的装置、用于减少下垫块与试样之间的下部减少摩擦的装置。本发明的装置利用特氟龙材料较好的减摩效应，有效地减少了垫块与试样之间的摩擦力的作用。
摘要（英）：

The invention belongs to the technical field of rock mechanics, and provides equipment for reducing an end-part frictional effect in a rock-fracture shearing-seepage experiment. The equipment comprises a shearing device for shearing a fracture rock sample, a seepage device for controlling flowing of fluid, friction reducing devices and a sealing device. According to the equipment for reducing theend-part frictional effect in the rock-fracture shearing-seepage experiment, the shearing device for shearing the fracture rock sample and the seepage device for controlling flowing of the fluid are arranged, the friction reducing devices are further arranged, the shearing device comprises a normal compression plate, a base, an upper cushion block and a lower cushion block, the fracture rock sample is placed between the upper cushion block and the lower cushion block, the upper cushion block is connected with the normal compression plate, and the lower cushion block is connected with the base.The friction reducing devices comprise an upper friction reducing device for reducing friction between the upper cushion block and the sample, and a lower friction reducing device for reducing friction between the lower cushion block and the sample. According to the equipment for reducing the end-part frictional effect in the rock-fracture shearing-seepage experiment, the good friction reducing effect of a Teflon material is utilized, and the friction action between the cushion blocks and the sample is effectively reduced.
