AB  - In this study Burger’s four element model was used to analyze rheological parameter of paddy soil of the Southern China. Two types of tool shape include circular shape (with an area of 12.56 cm2) and rectangular shape (with an area of 12.56 cm2) were use to measure the rheological parameter of paddy soil under different loading pressure (7.65, 10.20 and 12.75 kg) and soil water content (27 and 30%), the test was carried out an indoor soil bin. The results show that the Burger model possesses an excellent prospective for proper representation of the time dependent behavior of a stress-strain time graph curve can well imitate the tool structural change during the soil deformation under different soil water content. Overall results show that, the soil water content has great impact on soil deformation under different loading pressure, where proper tool shapes can control the soil deformation under different pressure. Soil water content on rheological parameter (Em, Ek, λm and λk) were predominantly significant, while loading on rheological parameter (Em, Ek, λm and λk) were not significant. The difference in the mean values among the different levels of M.C and Load has significant difference (p =
