柱下单独基础的直接设计法

Direct design method of under-column independent foundation

根据地基规范中柱下单独基础设计方法,通过理论推导,给出了这类基础底面尺寸、基础高度、基础底板弯矩的直接计算公式。按文中计算方法确定的基础底面尺寸、基础高度,能够充分发挥地基承载力和混凝土的强度,避免反复试算,使基础设计既经济又合理。

According to separate under-based design methods, the direct calculation formulae of the basic bottom size, the basic height, and the foundation slab moment are put. The calculation formulae of the basic bottom size and the basic height based on this method can fully develop subgrade bearing capacity and the concrete strength to make the basement design reasonable and simple. Compared with the existing calculation method, the method can avoid repeating spreadsheets and is more economical, reasonable.
