| 摘 要： | 通过软土地区桩基测试与规范计算结果的比较,结合桩基工作原理提出摩擦型单桩极限承载力计算的改进建议:应首先并着重考虑上部土层极限摩阻力的充分发挥,再逐级向下层累积计算;继而提出r侧摩阻力发挥系数的概念,以及单桩承载力的发挥应与土层相对位移相关.

| Abstract: | By comparison between the data generated from pile testing in soft soil zone and the calculated results based on code in addition to the working principle of piles,it is suggest that the calculation of ultimate bearing capacity for the frictional single pile should firstly allow for the maximum loading of friction resistance of upper soil,and then calculation of the accumulated loading of lower soil is made step by step,from which the concept of side friction resistance development coefficient is introduces... |
