摘　　要：提出预制裂缝的岩石直接拉伸的方法,即在岩石试样中部预制直线裂缝,然后直接拉伸,同时量测拉伸过程中岩石的变形数据,计算岩石的拉伸模量。预制裂缝的岩石直接拉伸方法可以避免传统拉伸方法所带来的问题,可以有效地进行岩石直接拉伸试验,同时可以获取岩石拉伸过程中的变形数据。This paper puts forward the method of direct tension of the rock, including in the middle of the rock specimen, at the straight line crack, to do the direct tension, and measure the rock deformation data in the process of drawing, calculating the tensile modulus of rock. The direct tension method of the pre fabricated rock can avoid the problems caused by the traditional tensile method, and can effectively carry out the direct tensile test, and can obtain the deformation data in the rock drawing process.
