| 摘 要： | 建筑物基础一般都是在地基中有一定深度的,而目前土中应力计算所常依据的布西奈斯克解却是假定荷载作用在地表面导出的,这与实际情况有很大的出入。本文以半无限体内受竖向集中力作用的明德林公式为根据,通过积分而首次完整地推导出竖向线荷载和条形均布荷载作用在地基内部时的土中应力分量的解析表达式,以便于工程设计人员在设计计算时使用。

| Abstract: | Up to now, the methods used for calculating stresses in soil are based on Boussinesq's for-mulus, which were derived on an assumption that the load was at the surface of ground. In this paper, on the basis of Mindlin' s formulus based on an assumption that a concentrated load was in the interior of a semi-infinite solid, formulus for calculating stresses in soil subjecting to vertical line load and strip distributed load at a certain depth beneath the surface of ground was derived. |
