| 摘 要： | 在对已有多桩型复合地基承载力计算方法进行充分研究的基础上,考虑多桩型复合地基受荷荷后的实际工作性状和施工方法对桩间土承载力的综合影响,引入主控桩、辅桩和桩间土承载力发挥系数及桩间土承载力提高系数,提出了多桩型复合地基承载力分步计算新方法。实例验证表明,复合地基承载力计算值与载荷试验实测值基本吻合。

| Abstract: | Based on the study of the existing calculation methods for the bearing capacity of multi-pile composite foundation,the working behavior of loaded multi-pile composite foundation and the general influence of different construction methods to the bearing capacity of the soil are considered.The coefficient of the bearing capacity exertion of master piles,the coefficient of the bearing capacity exertion of minor piles,the coefficient of the bearing capacity exertion of the soil between piles and the coefficient of the bearing capacity improvement of the soil are introduced.The new step-by-step calculation method for the bearing capacity of multi-pile composite foundation is put forward.The case shows that the computed results are accorded with the experimental date from loading tests. |
