摘　　要：桩基承载力的变化会引起桩基轴向刚性系数的变化,从而导致码头横梁内力的变化。通过对试桩资料进行统计分析,找出桩基承载力试桩值与计算值之间的差异,得到桩基轴向刚性系数的变化范围。运用STAAD软件进行计算分析,研究桩基刚性系数变化对码头横梁内力的影响,结果表明桩基承载力不同变幅导致上部结构内力变幅约在9%～27%之间。The axial stiffness coefficient of pile foundation varies with the bearing capacity,which leads to the change of wharf beam internal force.Through statistical analysis of test pile data,we found out the differences between the experimental and calculated value of the bearing capacity of pile foundation,and deduced the variation range of its axial stiffness coefficient.The software STAAD is used to calculate and analyze the influence of the change of stiffness coefficient of pile foundation on wharf beam internal force,the results show that the variation of bearing capacity of pile foundation leads to the variation of force in superstructure between9%and27%.
