发布时间:2018-10-10 11:32
【摘要】:首先从骨干曲线、滞回圈和累积变形这3方面总结粗粒土动力变形特性。然后给出理想弹塑性、非线弹性、粘弹性、和粘弹塑性等普遍本构关系式以及一些经典的本构模型。最后,针对路基粗粒土,分析给出的动力本构模型的适用条件,对粗粒土动力本构模型研究及其发展趋势进行探讨。
[Abstract]:Firstly, the dynamic deformation characteristics of coarse grained soil are summarized from three aspects: backbone curve, hysteresis loop and cumulative deformation. Then the general constitutive relations such as ideal elastic-plastic, non-linear elasticity, viscoelasticity, viscoelastic-plastic, and some classical constitutive models are given. Finally, according to the roadbed coarse grained soil, the applicable conditions of the dynamic constitutive model are analyzed, and the research and development trend of the dynamic constitutive model of the coarse grained soil are discussed.
