| 摘 要： | 在竖向变形相等的条件下,同时考虑了桩、土在固结过程中发生竖向和侧向变形、土体中的径向和竖向渗流以及土体水平渗透系数的3种变化模式,给出了此类复合地基固结问题的解析解,并对该解和不考虑桩、土侧向变形的现有解答进行了比较,最后对地基的固结性状进行了参数敏感性分析.结果表明:考虑桩体的侧向变形会降低地基的固结速率;桩、土的泊...

| Abstract: | Under the assumption of equal vertical deformation,an analytical solution is derived for the consolidation of composite ground by considering simultaneously the lateral and vertical deformations of column and soil,the vertical and radial flows in the surrounding soil and three variation patterns of the horizontal permeability coefficient of soil.The present solution is compared with some previous solutions ignoring the lateral deformations of column and soil.The consolidation behaviors of the composite grou... |
