This paper adopts the slice method to calculate the soil pressure of supporting structure and works out the corresponding computer program, the analyzed and computed results show that with the slice method calculating soil pressure, both the stratified soil and the nonlinear slip cracked face can accomplish the calculation by one program. The trial result shows: when slip crack face is a linear one, the calculated result of slice method is identical with that of Rankin's earth pressure theory and Coulomb's earth pressure theory, namely, the reliability of the slice method calculating soil pressure has been proved.
