长桩桩侧摩阻力分布与地基附加应力问题及对群桩沉降计算的影响OA北大核心CSCDCSTPCD
Distribution of shaft resistance of long piles and additional stress of foundation and their influences on settlement calculation of group piles
实测资料表明,工作荷载下传统Geddes解假设桩侧阻分布与长桩及超长桩实测侧阻分布差别较大,在工作荷载作用下长桩及超长桩桩身上部侧阻首先发挥。在对超长桩实测桩身侧阻分布的归纳总结基础上,建议了桩侧阻两段和三段线性分布模式,并通过对Geddes应力解的叠加,推导了两段和三段线性分布组合的侧阻分布模式下的地基附加应力解。建议侧阻分布模式与Geddes侧阻分布模式的对比分析表明,Geddes侧阻分布模式得到的桩端以下桩间土的竖向附加应力明显大于建议模式…查看全部>>
The measured data show that the distribution of shaft resistance of long and super long piles under vertical working load is quite different from the suggested one by Geddes' solution.The shaft resistance is first fully mobilized at the upper part of the long and super long piles under the working load.Based on the measured shaft resistance distribution of the long and super long piles,both the simplified bilinear and the trilinear patterns of the shaft resi…查看全部>>
