| 摘 要： | 根据明德林 (Mindlin)的垂直位移公式 ,导出了柔性矩形基础角点和中心点的沉降公式。将这些公式与基于布辛奈斯克 (Boussinesq)垂直位移解而导出的相应沉降公式作比较 ,求出两者的比值。计算并制定了这个比值与泊松比、矩形基础长 宽比和基础埋深 基宽比的关系表 ,以供工程应用。文中对深置矩形柔性基础的平均沉降量及深置矩形绝对刚性基础的沉降量 ,亦建议了计算方法。

| Abstract: | The settlement formulae for the center and corner point of a flexible rectangular foundation are proposed in the paper, it is based on the Mindlin theory. A comparison is made between the proposed formula and the formula based on the Boussinequ theory. The ratio of two results is calculated. Then, a correlation table among the Poisson ratio, aspect ratio, and depth?width ratio is made based on those ratios. At same time, a method to calculate the average displacement of deep flexible and rigid rectangular foundation is also suggested. |
