摘要:
由于传统的剑桥模型在处理黄土地层的二元结构时具有局限性,因此本文通过等应力比压缩试验和三轴排水剪切试验与分析计算结果的对比,分析研究了适合黄土地层二元结构的剑桥修改本构模型,最后提出适应性参数,试验证明本文提出的黄土二元结构本构模型符合实际,为黄土地区地下工程的设计与施工提供了分析研究的基础。
Abstract:
It is limited to solve the problem of dualistic structure of loess using original Cam-clay constitutive model. Compared with the analytic results of compressible expreriments by the same stress and the shear test in triangle condense,it researches and analyses the modified Cam-clay constitutive model and puts forward the corresponding parameter.It proved that the dualistic structure of loess is feasible,which make design and construction of underground engineering more appropriate and economic.
