With the improved one-dimensional compression creep consolidation apparatus, five sets of creep tests were conducted on specimens containing same content but different distribution of peat soil under the same experimental conditions, based on synthetic soil specimens which take organic matter as rheological phase material. That H-(H|N|V) four components fluid rheological model which introduces Duncan-Chang nonlinear instantaneous elastic modulus and only has a kinds of material parameters under different load levels was built and then the relationship between model parameters and distribution of rheological phase material were discussed. Some conclusions were drawn: fluid rheological properties of soft soil, which are not relative to the distribution of rheological phase material, can be accurately reflected by the proposed model and there is good relevance between the model parameters and rheological phase material.
