RHEOLOGICAL PHENOMENON OF THE SINK AGE AND HORIZONTAL DISPLACEMENT OF PADDY FIELD SOIL AND IT'S APPLICATION

摘要

This paper presents a general rheology model to illustrate the properties of time vs. sinkage and horizontal displacement curves of paddy field soil and rheology parameters could be deduced by the model. Rheology test equipments which could be used in lab and field have been developed by authors for obtaining the sinkage and horizontal displacement curves under a constant load. The prediction based on the experimental data and rheological model mentioned above for dynamic characteristics of tractor's drive wheel proved to be a reasonable approach.
