农桥是农用道路中以农业生产交通运输为主的桥梁。随着农业生产以及农田水利事业的发展,农桥工程的建设越来越重要,设计与施工任务也随之愈加繁重。农桥设计工作中,对支座的设计与施工,似乎很少引起人们的重视。桥梁的支座是上部结构与下部结构之间的重要连结部位,其构造必须满足设计中的计算要求。农桥的设计,大都按简支梁结构理论计算,一端为铰支座,允许上部结构在一定限度内产生角变位;另一端 Nongqiao is a bridge that takes agricultural production and transportation as the main road in agricultural roads. With the development of agricultural production and farmland water conservancy, the construction of Nongqiao project is more and more important, and the design and construction tasks will also become more and more heavy. Nongqiao design work, the design and construction of the support, it seems rarely cause for people’s attention. The bearing of the bridge is an important connection between the superstructure and the substructure, and its structure must meet the calculation requirements in the design. Nongqiao design, mostly based on the theory of simply supported beam structure, one end hinge support, allowing the superstructure to produce angular displacement within a certain limit; the other end
