摘要
通过一系列单轴无侧限抗压强度试验,对温度及加载速率对河冰抗压强度、应力—应变关系、弹性模量的影响进行了研究。通过统计分析与曲线拟合,得出抗压强度与温度间的相关关系。通过试验,得出河冰的应力—应变曲线,并对河冰弹性模量值的取值进行了探讨。
Pass to carry on a series of uniaxial and unconfined compression test towards Huma river ice, it can be researched that the influence of temperature and rate of loading to compressive strength, strain- stress, elastic modulus. Pass to checkout the influencing prominence degree of temperature to compressive strength and match the rehtionship of temperature and compressive strength, an empirical formula can be educed. It can be get the elastic modulus of Huma river ice from the strain - stress loops and the points of toughness and brittleness is reflected.
