摘　　要：弹性模量和泊松比是岩石最重要的弹性参数,是衡量岩石抵抗弹性变形能力大小的尺度。为了满足资源勘查工程专业学生的理论及实践教学需要,本文通过设计并制作了机械法岩石变形实验的夹具,利用压力机对圆柱体岩石试样施加一定的轴向压力,用4个轴向千分尺测量岩石的轴向应变,并利用径向的8个千分尺测量岩石试样的径向应变,实现了岩石弹性模量和泊松比的测量和计算。本实验有利于学生更好的掌握岩石变形特征和机理,增强了学生的实践动手能力。Modulus of elasticity and Poisson＇s ratio are the most important elastic parameters of rock,and are themeasure of the ability of rock to resist elastic deformation.In order to meet the needs of theoretical and practical teachingof students majoring in resource exploration engineering,this paper designed and fabricated the fixture for mechanicalrock deformation experiment,using the press machine to apply a certain axial pressure to the cylindrical rock specimen,measuring the axial strain of the rock with 4 axial micrometers,and measuring the radial strain with 8 radial micrometers,measuring and calculating the rock elastic modulus and Poisson＇s ratio of rock specimen.This experiment is beneficial forstudents to better understand the characteristics and mechanism of rock deformation and enhances students＇ practicalability.
