【摘要】 通过对类岩石进行不同加载速率下的单轴压缩试验，探究加载速率变化对类岩石应力-应变曲线的影响.研究结果表明：在一定范围内，随着加载速率的增加，类岩石的峰值应力呈递增趋势；在恒速率试验中，不同速率所对应的应力-应变曲线不相同；在变速率试验中，当速率突然增大时，应力-应变曲线会有明显的向上突变；不同速率也会影响类岩石的裂纹发展.更多还原

【Abstract】 Through uniaxis compression tests on quasi rock materials at varying loading rates, this paper aims to discuss the influence of rate changes on the stress-strain curves of quasi rock materials. The research results show that within a certain range, an increase in loading rate leads to a corresponding increase in the peak stress of quasi rock materials. In constant rate test, the stress-strain curves corresponding to different rates are different. In variable speed rate experiment, when the speed suddenly increases, the stress-strain curve will have obvious mutation upwards. In addition, different rates also affect the development of quasi rock cracks.更多还原
