This paper analyzes calculates the soil pressure of the sheet-pile wall on the rock-bedded slope with PLAXIS, discusses the variation trend of the soil pressure and horizontal displacement with different inclination angles, and obtains the value and distribution of the sheet-pile wall on the rock-bedded slope. The research results show that the total lateral soil pressure of the sheet-pile wall first increases and then decreases with the increment of the inclination angles, the soil pressure does not present the simple linear increase distribution, but an irregular distribution, the maximum soil pressure presented on the freeing surface or the bottom of the sheet-pile wall. The results may serve as a reference for the perfection of the Technical Code for Building Slope Engineering.
