结合某轨道交通高架桥梁(66+110+63)m连续梁,介绍单箱单室直腹板连续箱梁的构造要点、设计参数、内力包络以及计算结果.连续梁具有的刚度大、变形小、行车舒适性高等优点,是近年来轨道交通高架桥梁领域较为适合的桥梁结构.
結閤某軌道交通高架橋樑(66+110+63)m連續樑,介紹單箱單室直腹闆連續箱樑的構造要點、設計參數、內力包絡以及計算結果.連續樑具有的剛度大、變形小、行車舒適性高等優點,是近年來軌道交通高架橋樑領域較為適閤的橋樑結構.

In this article, the author combines with a continuo-us beam of rail transit elevated bridge (66+110+63) m to intr-oduces the construction details, design parameters, internal for-ce envelope and calculations of single cel box straight web co-ntinuous box girder. The continuous beam has many adventag-es of great rigidity, smal deformation and driving comfort etc. It’s a more appropriate bridge structure in rail transit elevated bridge areas in recent years.
