钢筋混凝土条形基础的直接设计法

Section Design of Strip Footing with Reinforced Concrete

将混凝土条形基础视为悬臂梁,而向上的土压力则是作用在梁上的荷载,结合现行《建筑地基基础设计规范》和《混凝土结构设计规范》的规定,基于基础的剪切承载力、弯曲承载力和刚度要求,导出基础底板高度及配筋的直接求解公式,研究成果为此类基础设计和规范修订提供参考。

The concrete strip foundation is considered as a cantilever beam, the upward pressure on theearth is the load on the beam. Combined with the existing ＂code for design of building foundation＂ and ＂concrete structure design code＂ provisions, based on the shear bearing capacity, bending bearing capacityand stiffness requirements, the direct solution formula of the height of the base plate and the reinforcementof the foundation were derived. The research results provided reference for the design and revision of thiskind of foundation.
