Application of Negative Frictional Resistance of Pile Foundation on Deviation Correction

Abstract:

Empirical formula of downward load of pile foundation is presented based on analyzing characteristic of negative frictional resistance of pile foundation. Feasibility of the proposed formula is verified by a deviation correction engineering of deep pile foundation, which supplies theoretical foundation for application of negative frictional resistance of pile foundation on building inclination correcting engineering and supplies an effective method for building inclination correcting technology of deep pile foundation.
