Sheet pile is a composite bearing body composed of pile and plate.It is a composite foundation which uses the soil arch effect of the soil covering cushion on the plate to transfer the uniform load of the upper part to the pile foundation to the maximum extent to improve the bearing capacity of the foundation.Through engineering comparison and selection

it is economical and reasonable to apply sheet pile to the foundation treatment of coal piling area in circular coal yard.In order to study the influence and effect of pile spacing

plate area and covering cushion thickness on foundation bearing capacity

PLAXIS 3D finite element analysis software was used to calculate and compare the multi-working conditions

analyze the main factors affecting the pile-soil stress ratio of plate piles and their influencing laws

and draw suggestions suitable for this project.
