本文建议了一种双链杆解法,用以考虑基底剪力对基础反力和内力的影响,并对交界面为光滑接触、粗糙接触和库伦摩阻等不同假设下的基础梁的反力和内力特点进行了详细的讨论。(一)计算假设与计算方法在建立梁的实用计算理论时,一般假设梁与地基间为光滑接触,地基只产生法向反力。这个假使问题的研究得到很大简化,但与 This paper proposes a double-link solution to consider the effects of base shear forces on the basic reaction forces and internal forces, as well as the reaction forces of foundation beams under different assumptions such as smooth contact, rough contact, and Coulomb friction. The characteristics of internal forces were discussed in detail. (I) Calculation assumptions and calculation methods When establishing a practical calculation theory for beams, it is generally assumed that the beam is in smooth contact with the foundation and the foundation only produces normal reaction forces. If this study of the problem is greatly simplified, but with
