Abstract

Abstract: Based on the application of precast pipe pile in Peitun area in Xuzhou，the numerical model of pile-soil is established with FLAC3 D．The mechanisMof interaction between pipe pile and soil under vertical loading is analyzed，including the load transforming rule，stress features and failure modes，according to the established numerical model of pile-soil．The results provide a theoretic foundation for the further analysis on the bearing mechanisMof pipe pile

Key words: precast pipe pile, FLAC3 D, numerical simulation, interaction between pile and soil

摘要： 以徐州市沛屯地区预制管桩的应用实例为基础，以FLAC3D软件为分析手段，建立了管桩桩土数值模型，通过该数值模型对管桩在竖向荷载作用下桩土共同作用机理，包括荷载传递规律、受力特性和破坏模式进行了分析，为进一步研究管桩承载机理提供了理论基础
