摘要
新建铁路与既有铁路小角度交叉,一般采用框架墩+简支梁的桥跨形式,但是框架墩结构高度高,本文提出的框架简支板桥能够很好地解决这个问题,并且从施工和设计角度论证了工程的可行性。研究结果:框架简支板在设计上强度、刚度满足规范要求,施工可行,具有较好的经济价值,值得推广应用。
When new railway crosses the existing railway with a small angle, frame pier is generally adopted, but the frame structure is high. The frame structure with simply supported plate proposed in this paper may solve the problem properly and is proved applicable in prospective of construction and design. The research results demonstrate that the frame structure with simply supported plate satisfies the specification and is practical and economical.
