摘要
本文探讨了冰碛土的微观结构特征,分析研究了在高低应力条件下的应力-应变-体变特性,并阐明了影响这些特性最主要的因素。按照这些研究成果,建议了新的考虑剪胀和软化特性的非线性K-G模型。
Characteristics of microstructure of till are studied. Behavior of stress-strain-volumetric change of till under high and low stresses is analysed systematically, and major factors affecting the behavior are also indicated. A new non-linear K-G model which involves volume dilatancy and stress working soften is proposed.
