| 摘 要： | 根据不同工程地质条件,给出了可供选择的组合桩型复合地基设计方案。在确定组合桩型复合地基承载力时,考虑组合桩型复合地基受荷后的实际工作性状、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,提出了组合桩型复合地基承载力分步计算新方法。实例验证表明:采用本研究公式所得复合地基承载力计算值与载荷试验实测值基本吻合。

| Abstract: | According to different conditions of engineering geology,some available schemes of combined pile composite foundation are proposed.In order to perfect the design theory,in the process of identifying the bearing capacity,the actual working behaviors of combined pile composite foundation after it is loaded, and the general influence of construction methods on the capacity of the soil between the piles have been considered.The bearing capacity developing coefficients of the master pile and the minor pile and t... |
