横向力作用下的刚性基础,因具有足够的刚度而产生整体转动,其轴线的挠曲可略去不计。任一深度处的侧向位移均与转动中心有关。这一条件使刚性基础相应的位移分析得以简化,并提出许多“刚性基础”的解。基础与岩土接触面间的摩阻力对刚性基础侧向受挠的特性有时会产生显著的影响,而在许多“刚性基础”解中未予考虑。本文采用地基—反力理论,给出了考虑侧向摩阻力时的解,其中任一点的反力与该点的挠度及深度的幂函数成正比。
The rigid foundation under the action of lateral force, due to having sufficient rigidity, produces overall rotation, the deflection of its axis can be neglected. The lateral displacement at any depth is related to the center of rotation. This condition simplifies the corresponding displacement analysis of the rigid foundation and proposes many solutions to the “rigid foundation”. The frictional resistance between the foundation and the geotechnical interface sometimes has a significant effect on the lateral flexural behavior of the rigid foundation, which is not considered in many “rigid foundation” solutions. In this paper, the solution of the lateral frictional resistance is given by the foundation-reaction theory. The reaction force at any point is proportional to the power function of the deflection and depth of the point.
