黄土平面蠕变模型
Plane creep model of loess
摘要
Abstract
In geotechnical engineering,agricultural engineering and hydraulic and hydro-Power Engineering etc.,many problems such as long-term stability of dam and slope,could be regarded as the plane strain issue.Hence,these questions are always figured out though as the plane creep tests,which are more suitable to the engineering conditions.In order to deeply investigate the plane creep properties of loess soil,a series of laboratory consolidated plane creep tests of loess are conducted by a reformed plane creepmeter in this paper,and the tests results show that the deformation of plane creep is dramatic under high water content,high deviatoric stress and low consolidation condition.Base on the analysis of experimental data,a new empirical model is proposed.In addition,it is found that the two existed models named Singh-Mitchell and Mesri models,which are usually utilized to model the creep problems of soils,are not suitable for loess in the plane strain condition.However,the model proposed in this paper can better describe the creep proprieties of loess in the plane strain condition,due to its merits in both higher accuracy and fewer parameters.关键词
