摘要
采用有限元方法对水平荷载作用下单桩试验进行数值模拟,以土弹簧取代桩周土体作用,提出了由实测试验桩数据推导求得土弹簧刚度的方法,此方法可应用于各种荷载作用、泥面坡度情况下桩的桩-土相互作用。计算结果表明有限元模拟结果与试验实测数据基本吻合,可以为工程实践与设计提供重要理论依据。
A finite element analysis method is adopted to conduct numerical simulation on single pile under lateral load test, the effects of surrounding soil are replaced by soil springs and a new method is put forward for soil spring stiffness derived from test data. This method can be applied in various pile - soil interaction circumstances with different loading and soil surface gradients. The calculation results indicate that the finite element simulation results are basically consistent with the experimental measured data, which can provide an important theoretical basis for engineering practice and design.
