开启桥是一种能够解决水陆交汇之处客观条件不允许建造足够桥下净空的固定桥时所采用的一种桥梁形式,其开启形式多种多样。主要研究了在垂直提升方式的开启桥中支承轮的结构设计,并通过有限元的方法进行结构优化。 Opening a bridge is a form of bridge that can be used to solve the problem that the objective conditions of water-land intersection are not allowed to build a fixed bridge under the bridge. The opening form is various. The structure design of the support wheel in the open bridge with vertical lifting is mainly studied and the structure is optimized by the finite element method.
