摘 要: 根据地基、基础的受力和变形特点,利用地基在设计荷载作用下,地基受力和变形的关系,将各种不同的地基简化为一个个不同的弹簧支座,根据基底的附加应力和沉降,计算出弹簧支座的刚度。从而将地基、基础的弹性力学分析转化成力学问题求解。将弹性地基上的框架转化为有限个弹簧支座的框架,再对其进行结构计算。这种新的计算模型将上部结构、基础和地基按共同作用进行受力分析,计算简图完整,传力和受力明确,方法简单,计算结果能满足工程设计的需要。
关 键 词: 水工结构;结构计算;弹簧支座;模型;泵闸

Abstract: Based on force and deformation features of foundation and base, the paper considers the relationship between force and deformation of foundation, simplifies the foundations to spring bearings, and calculates the rigidity of spring bearing according to the additional stress and settlement of foundation. Thus the elastic mechanics problem of the foundation and base is transformed to the normal mechanics problem. The paper transforms the framework on the elastic foundation beam to the framework on the limited spring bearing, then takes the structural calculations. In this new calculation model, the superstructure, base and foundation are analyzed as a whole, the diagram is integrated, the force is clear and the calculation is simple. The method can meet the needs of engineering design.
Key words: hydro-structure; structural calculation; spring bearing; model; pumping station and sluice
