摘　　要：采用静载试验的方法,从荷载传递角度研究饱和软土中的预制桩经过不同休止期后,桩身不同部位的侧摩阻力及桩土相对位移随时间的变化规律,本质上分析了饱和软土中摩擦桩时效性对承载力的影响。Through the method of loading test,the change of shaft resistance and relative displacement between pile and soil under different rest time in different part of precast pile in saturated soft soil are researched from the perspective of load transfer.Time-effect on bearing capacity of friction pile is analyzed in substance.

关 键 词：荷载传递 极限侧摩阻力 承载力 时间效应
