摘要
对桩侧土和桩端土分别采用三折线荷载传递软化模型和三折线全塑性荷载传递模型 ,利用土力学及弹性理论导出了一套完整的确定层状土中桩轴向荷载 沉降关系的解析算式。同时 ,利用株洲地区桩侧摩阻力及深井试验测定的土工计算参数 ,通过本文方法对某工程试桩进行了计算对比 ,其计算值与实测值相当吻合 。
Tree linear transfer softening model and tree linear wholly plastic load transfer model are used separately for pile side soil and pile end soil.Based on soil mechanics and elastic theory,a set of analytical equations for the axial load settlement curve of pile top in layered ground are established.Meanwhile,based on soil mechanics parameter obtained by pile side friction force and deep hole testing at Zhuzhou area,the results acquired by this method are contrast to the testing results.Calculating results is conformable to the test results.Thereby the proposed method will be of practical significance in design of pile foundation.
