【摘要】 基于Mindlin位移解,假设桩身为完全弹性,外荷载作用下桩、土之间有相对位移,桩、土之间的摩阻力是相对位移的函数,以考虑桩周土体的塑性,建立了方程组,采用有限差分方法进行求解。计算了两个工程实例,并同实测结果进行了比较。计算结果表明,该方法同实测结果吻合得较好。该方法的突出优点是可以考虑群桩中桩、桩与桩、桩与土的相互作用关系。更多还原

【Abstract】 Based on Mindlin’s solution, it is assumed that pile is elastic, and there is relative displacement between pile and soil, and a group of equations are established and solved by finite difference method. Two examples are given, and the calculated results agreed well with testing data. The advantage of this method is that the interaction of pile and pile, and pile and soil can be considered.更多还原
