The buildings are constructed on the slope side, to avoid digging massively fill geotechnical Engineering, according to the slope potential's change, the pile foundation makes not the contour form generally, when the subsoil water level rises or the reservoir stores, partial pile bottom is often under the water level,which causes the ground the supporting capacity and the rigidity to change.Adds it when the structural design “the pile- earth-superstructure” will be separated from the consideration frequently, even if considering it together frequently also often neglects the influence of the water level change on the overall construction.As the accident which according to this design's construction structure the dehiscence or the entire construction collapse sometimes occur. In order to avoid this kind of accident's occurrence, we must make it clear that the influence of the water level change on the structure supporting capacity. Based on this, this article takes some storehouse ashore 8 portal frame construction's pile foundation as an example, through finite element software establish “pile-earth-superstructure” three-dimensional moldel, the model analyzes the pile, the earth and the superstructure internal force and displacement's change under the water level change. The analysis result indicated that the water level change causes the structure the internal force and the distortion increases,particularly the pile foundation exists changes the region highly the superstructure.When construction structural design should be considered fully the influence of the groundwater level change on the superstructure,thus makes the structural design be safer reasonably
