摘　　要：　介绍了利用位移协调法分析基桩承载特性的理论基础及计算方法。根据郑州某工程的静载试验资料,求得桩身荷载的传递函数,并利用该函数对基桩承载特性进行了分析。得出了可利用实测传递函数对同一场地的不同桩长、桩径或具有相同工程地质条件的不同场地的基桩进行承载特性分析的结论,以及桩端土层的力学指标和桩身弹模的选取对计算结果有较大影响的结论。The theory basis and calculating method for analyzing pile's bearing properties by harmony of displacement is introduced. According to the data of the static loading test of the project of Zhengzhou,We obtain the transfer function of the pile axis pressure and analyze the bearing properties of pile by using this function. The conclusions of using measuring transfer function to analyze bearing properties of pile in different long or diameter or in different area of the same geological situations are drawn. In addition the selection of physical and mechanical properties parameter and pile's elastic modulu influences the calculation conclusion.
