摘要
设计研发了适用于圆柱形岩石试样的直剪试验装置,弥补了现有岩石剪切试验机TEST60只能开展方形岩石试样直剪试验的不足。此外,还对岩石剪切试验机TEST60中的竖向加载压头加装了改进后的球形压头,从而在加载测试过程中施加分布均匀的正应力,进而得到更精确的直剪试验结果。这不仅能够更好地满足实践和科研的需要,而且还使教师与学生不断学习新知识和新技术,为进一步提升实验教学质量,促进实验教学改革与学科间的交叉融合奠定了良好的基础。
A direct shear test device for cylindrical rock specimens is designed and developed,which makes up for the shortcomings of the existing rock shear testing machine TEST60 which can only carry out the direct shear test for square rock specimens.In addition,an improved spherical indenter is added to the vertical loading indenter in the rock shear testing machine TEST60 to apply a uniform distribution of normal stress during the loading test,and then resulting in more accurate direct shear test results.This can not only better meet the needs of practice and scientific research,but also enable teachers and students to hunt extensively and continuously learn new knowledge and new technologies in order to further improve the quality of experimental teaching,and promote the experimental teaching reform and cross-disciplinary integration between disciplines laid a good foundation.
