本论文采用一套刚性组件,在200吨普通压力试验机上测定了复合岩石在单轴受压状态下的应力——应变全曲线,为了比较又测定了组成复合岩石的砂岩、泥岩及灰岩的应力——应变全曲线。通过试验研究发现:接触边界效应对复合岩石的力学性态有很大的影响;复合岩石在峰值强度后,仍然具有承载能力;复合岩石的破坏是一个累进性的破坏过程。本文以试验数据为基础,对复合岩石在单轴受压状态下的应力——应变全过程作了详细的分析和讨论。 In this dissertation, a set of rigid components was used to determine the stress-strain curve of a composite rock under uniaxial compression on a 200-ton ordinary pressure tester. In order to compare the sandstone, mudstone and limestone of composite rock, Stress - strain full curve. Through experimental research, it is found that the contact boundary effect has a great influence on the mechanical behavior of the composite rock; the composite rock still has bearing capacity after the peak strength; the destruction of the composite rock is a progressive destruction process. Based on the experimental data, this paper makes a detailed analysis and discussion on the whole stress-strain process of composite rock under uniaxial compression.
