摘　　要：通过不同的桩刚度取值对工程实例做对比,试图研究桩刚度不同取值对桩基基础受力的影响。分析对比结果显示,桩刚度的不同取值将会影响桩受力及底板受力的分析结果,极端情况下可能导致局部桩破坏失效,进而引起整体抗浮失效的多米诺骨牌效应。桩刚度对底板内力结果也有一定影响,不正确的取值可能造成板内力计算结果失真,甚至导致板破坏。This paper compares engineering examples with different values of pile stiffness,attempting to study the impact of different values of pile stiffness on the stress of pile foundation.The analysis and comparison results show that different values of pile stiffness will affect the analysis results of pile force and bottom plate force.In extreme cases,it may lead to local pile failure,leading to a domino effect of overall anti floating failure.The pile stiffness also has a certain impact on the internal force results of the bottom plate,and incorrect values may cause distortion in the calculation results of the internal force of the plate,and even lead to plate failure.
