【摘要】 有限变形问题愈来愈引起岩土界的重视,文中综述了当前国内外土体有限变形本构模型和非线性固结理论研究的现状和进展;对两种变形率加法分解和变形梯度乘法分解塑性理论作了较详细的介绍,并进行了简要分析和比较;评述了一种新的土体有限变形非线性固结理论—混合物理论,并提出了今后需要进一步研究的问题。更多还原

【Abstract】 The recent advance in finite-deformation constitutive model and nonlinear consolidation theory of soils is reviewed in the paper.Two classes of plasticity theory,which are based on additive decomposition and multiplicative decomposition respectively,are emphatically introduced and apprised.A new nonlinear consolidation theory of-mixture theory is discussed.Finally,suggestions are made for future research.更多还原
