| 摘 要： | 结合叠合小应变模型和结构性土的损伤理论,提出了可以考虑土的结构性损伤对小应变下刚度的影响的小应变模型。该模型可作为其他常规土体本构模型的数据接口模型,从而使其他常规本构模型能充分反映土体的小应变特性。通过与实验资料比较分析表明模型可以有效模拟结构性土体的小应变特性。

| Abstract: | Combining the small strain overlay model with damage theory,a practical Small strain model for structured soil is developed,which can consider the effect of damage in structured soils on stiffness variation under small strain.This model could be taken as the interface model for other normal elastoplastic constitutive models to take them into account the small strain behavior.Through comparison with the experimental data,it is proved that this modle can simulate effiectively the charactersistics of small str... |
