Analyses of the Position of Earth Pressure Zero Point of Single Fulcrum Row Piles Supporting Structure

In the supporting structure design of foundation pit,the equivalent beam method is one of the classic methods of calculating the internal force of support structure.With a foundation pit project as an example,the single point row piles support structure was designed and calculated with the equivalent beam method.The differences of the position of earth pressure zero point by using different methods and the influence of the position of earth pressure zero point on the displacement and internal force of piles were analysed.Finally,according to the analysis results of this paper,some suggestions were proposed about determining reasonably the position of earth pressure zero point for designing reference.
