1概述弯桥的平面形状和构造都比较复杂。直梁弯桥由于设计、施工简单，中小跨径的弯桥多采用这一形式；曲梁弯桥施工复杂，技术要求高，一般只在大型和有特殊要求的桥梁中应用。将直梁弯桥应用在缓和曲线中，这方面的实践不多。2缓和曲线上的桥梁布置直梁弯桥按桥梁墩、台的平 1 Overview The curved shape and structure of the bridge are more complex. Straight curved bridge due to the design and construction is simple, small and medium-span curved bridge to use more of this form; curved curved bridge construction complex, high technical requirements, generally only in the large and have special requirements of the bridge. The straight beam curved bridge used in the easement curve, this practice is not much. 2 ease the curve of the bridge layout Straight beam bending bridge by the bridge pier, Taiwan’s flat
