通过对西南交通大学某教学楼箱形基础基底反力的实测结果，得出了“Ⅰ”形平面箱基置于密实卵石层上的基底反力分布规律，又用有限压缩层地基模型对该箱基反力进行了计算，结果表明：实测反力与计算反力分布规律一致，实测反力平均值与计算反力平均值相对误差为６．９％，也说明此法计算箱基反力是可行的。

Based on the measured results of the basement reaction of the box foundation of a teaching building in Southwest Jiaotong University, the law of the basement reaction force distribution of the “I”-shaped flat box foundation on the dense pebble layer was obtained, and the finite-compression layer foundation model was also used. The counterforce of the box foundation was calculated. The results show that the measured counterforce is consistent with the calculated law of counterforce distribution. The relative error between the average value of the measured counterforce and the average value of the calculated reaction force is 6.9%. It also shows that this method calculates the reaction force of the box foundation. It works.
