摘要
Coarse-grained soil can used as high filling embankment in mountainous area, but rheological deformation of coarse-grained soil continue long time, which may cause the transfinite of post-construction settlement under long-term load. Coarse-grained soil engineering properties are greatly influenced by particle size composition, triaxial test for coarse-grained soil stress-strain relationship, result show that: stress levels and confining pressure effect rheological properties of coarse-grained soil, coarse-grained soil presents nonlinear viscoplastic deformation characteristics. Rheological calculating formulas of coarse-grained soil embankment are established based on Merchant model. Result shows that the total settlement which calculated by the formulas is more conservative than standard method.
