摘要:
传统的本构模型多是在重塑土或饱和砂土的基础上建立起来,考虑结构性影响较少。自然界中土体大多具有结构性,这样就使得按传统方法计算的结果与工程实际有一定的差别。基于此,本文以Mesri模型为基础,将结构损伤变量引入模型中,建立了考虑结构性影响的流变模型。通过对天津滨海新区吹填场地经过真空预压处理的结构性吹填软土进行三轴流变试验,分析比较计算结果表明,本文建立的模型能够较好地反映结构性软土的应力应变随时间的变化关系。
Abstract:
Most of the traditional constitutive models are based on the remolded clays or saturated sand, in which the effect of structure is not considered. Generally speaking, natural soil has structure, the calculated values through traditional constitutive models are not fitted to the engineering practice. For this reason, based on the Mesri model, a rheological model is established, in which the structural effect is considered through introducing the soil structure damage variable into the model. Through triaxial rheological test on structured soft dredger fill which is treated by vacuum preloading in Tianjin Binhai New Area, the calculation results show that the new established model can reflect the relationship between stressstrain change and time of structured soft dredger fill.
