摘要
建筑物基础一般都是埋入地基中,且有一定深度,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。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矩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,并与布氏公式进行比较,说明其应用范围,以便于工程设计人员在设计时使用。
Traditionally, the method for the calculation of the stresses in soil is based on the Boussinesq's formula which was derived on the assumption that the loading acts on the surface of the ground. This paper, on the basis of the Mindlin's formula which changes the assumption that the loading acts at a certain depth beneath the surface of the ground, the authors have derived a new formula for the calculation of stresses in soil subjecting to uniformly distributed loading at a certain depth beneath the surface of the ground.
