K0固结软黄土的不排水抗剪强度模型
Model of undrained shear strength of K0 consolidated soft loess
摘要
Abstract
In order to accurately predict the undrained shear strength of saturated soft loess in engineering construction site,this paper derives a generalized body-strain equation ine-lnp'space,based on the K0 consolidated soft loess model that takes into account structural properties and anisotropic characteristics.The structural stress ratio is also introduced to reflect the influence of soil consolidation history on the undrained strength of the soil,and on this basis the theoretical model for calculating the undrained shear strength of K0 consolidated soft loess is derived in compliance with the body strain law under undrained conditions.The result shows the calculation model proposed in this paper can predict the undrained strength of saturated soft loess more accurately.The relationship between the main parameters of the model and the undrained strength of the soft loess is further explored by parametric analysis,which shows that the undrained shear strength ratio of the soft loess is negatively correlated with the plasticity parameter and positively correlated with the structural parameter and structural stress ratio.关键词
