摘要
基于纤维风积沙土的不固结不排水三轴剪切试验,为实现应变硬化型纤维风积沙土应力—应变关系的归一化,基于应变硬化型典型的双曲线特征,提出了以固结围压作为归一化因子。通过以固结围压为归一化因子,对纤维风积沙土应力—应变特性进行归一化分析和比较表明,纤维风积沙土的应力-应变特性归一化程度更高,效果更好。同时,建立了应变硬化型纤维风积沙土应力—应变特性的归一化方程。
Based on fibre eolian sandy＇s non-consolidated and undrained triaxial shear tests, in order to realize stress strain hardening relation of aeolian sand normalizing and based on strain hardening characteristics of a typical hyperbolic, consolidation conffining pressure as a normalization factor is presented. Meanwhile, a strain hardening of aeolian sand, fiber stress - strain behavior of the normalized equation is estddished.
