| 摘 要： | 在分析基桩的有效桩长计算现状及存在的问题基础上,假设桩侧摩阻力呈抛物线型分布,根据桩土顶面的位移协调条件,利用Mindlin位移解推导了有效桩长的计算公式,将其结果与桩侧摩阻力呈其它形式分布得到的有效桩长和实验数据进行比较,得出假设桩侧摩阻力呈抛物线分布时有效桩长解更接近实测数据更准确.为了将理论分析解应用到工程桩中,...

| Abstract: | Based on analysis of the status and existing problems in the calculation of effective length of piles,the pile shaft resistance distribution is assumed to be parabola-shaped.The formula for calculating the effective length of piles is proposed according to the displacement compatibility conditions at the top of pile-soil and the Mindlin displacement solution.The comparison of results by using this formula and results based on the hypothesis that the pile shaft resistance distribution was triangular-shaped w... |
