Abstract
Frame-type levee is common type of levee in southern China. The deformation of pile foundation of frame-type levee is affected greatly by the river level. Large deformation is its notable feature. Taking levee project located in Wuzhou city of Guangxi province of China as research background, “P-Y curve” method is used to analyze the deformation and internal force of pile foundation of frame-type levees under the different working conditions. The results show that the maximum deformation of pile foundation reaches 0.18m, which imply the pile foundation is not safe under the condition of high river lever during flood season. Furthermore, the results show that “P-Y curve” method is feasible for simulating the pile with large deformation. It overcomes shortcomings of traditional methods such as “K” method or “M” method, which are not applicable to simulating pile with large deformation.
