摘要

基于线性形式的临界状态线(CSLs)，建立了土的初始状态相关分数应力-剪胀方程。然而，实验证据表明，由于材料的显著降解，p ' -q和e-p '面土壤的csl也可能是非线性的。本文旨在提出具有任意类型csl的土壤的统一FSD方程。给出了详细的推导。为了验证所提出的FSD方程，模拟了一系列压舱物和堆石料的三轴试验结果。

Fractional stress-dilatancy equation based on critical state lines with arbitrary form

The original state-dependent fractional stress-dilatancy (FSD) equation for soils is developed based on the critical state lines (CSLs) with linear form. However, experimental evidences showed that the CSLs of soil in the p ′–q and e–p ′ planes could be both nonlinear as well due to significant material degradation. This note aims to propose a unified FSD equation for soils with arbitrary types of CSLs. Detailed derivations are provided. To validate the proposed FSD equation, a series of triaxial test results of ballast and rockfill are simulated.
