| 摘 要： | 统一硬化模型（UH模型）能够描述超固结土的硬化、软化、剪胀和剪缩等应力-应变特性以及应力历史对土的影响。基于增量弹-塑性模型的基本假设,根据一元二次方程的解法,推导出塑性因子的表达式,由变换应力公式推得变换应力增量与真实应力增量的关系,进而得到UH模型在FLAC3D中的计算格式。基于FLAC3D软件提供的二次开发平台U...

| Abstract: | The over-consolidated unified hardening model(UH model) proposed by Yao et al can describe many characteristics of over-consolidated clays well,including stress-strain relationships,stress dilatancy,strain hardening and softening,and stress history dependency.Based on the assumption of elastic-plastic model and solution of a quadratic equation,the computational scheme of UH model in FLAC3D was derived.According to the secondary developing platform,the UH model was developed in FLAC3D with Visual C+ +environ... |
