| 摘 要： | 弹性地基上箱形基础基底反力的计算是一个没有很好解决的问题,按各种方法计算得出的结果相差很大,并且与实际情况不甚符合。本文通过对一般第四纪土及软土地基上的高层建筑箱形基础基底反力的实测及分析,获得不同地基上上、不同长宽比的箱形基础基底反力分布曲线,计算出了基底平面的反力系数表。按本文提出的方法进行计算比较简便,其结果也比较接近实际情况。

| Abstract: | Althougth the computation of the subgrade reactions under box foun- dation on elastic subsoil has been studied for a long time, the problem is not well solved yet. The results obtained from various methods are quite different. Based on the measurement and analysis of subgrade reactions under box foundations of seven existing multistory buildings on quaternary period soil and soft soil, reaction distribution curves for different subgrade and different length-width ratio of box foundation are obtained. The coefficients of the subgrade reactions are tabulated for practical use. The results computed by the proposed method are compared with those obtained from other methods. The proposed method is found to be simple and its results are rather close to the existing conditions. |
