The author proposeu the expressions (1), (4) in the previous papers in order to estimate the soil thrust in paddy fields in our country. From the model test in our laboratory, the author found that the expression (1) could be applied for the estimation of τ-ε curves, from which the soil thrust could be calculated, but there are considerable difference between the experimental values and the calculated values due to the disagreement between the shearing mechanism, the height and shapes of lug and of compressive plate of Burggraf Shear Apparatus. The author would like to make much efforts to obtain more precise soil thrust formula
