摘要
为使一种插接式拼装独立基础在工程应用上获得具体的理论指导,提出了一种适用于该类型基础的通用设计计算方法。设计计算方法中假定接触面仅仅承受法向压力,忽略摩擦力。根据平衡关系和叠加原理,详细地求出了主块与辅块接触面的法向压力,从而,获得了主块、辅块危险截面的内力解析式,确定了各块的配筋形式。进一步,阐述了确定主辅块合理高度的思路,为插接式拼装独立基础的工程应用提供了理论依据。
In order to obtain a specific theoretical guidance for a kind of prefabricated foundation characterized with plug-in assembly in engineering application,a generic design and calculation method suitable for this type of foundation is proposed.The design and calculation method assumes that the contact surface only bears the normal pressure and ignores the friction.According to the equilibrium relationship and superposition principle,the normal pressure on the contact surface between the main block and the auxiliary block is obtained in detail,and,analytical formulas of the internal force in the most dangerous sections are obtained as well the reinforcement patterns for each block is determined as.Furthermore,the process of determining the reasonable height of the main and auxiliary blocks is stated.All of formulas proposed provided a theoretical basis for the engineering application of this kind of prefabricated foundation.
