Micro-arch thin-beam portal rigid frame bridge
The invention discloses a micro-arch thin-beam portal rigid frame bridge beam, which aims to optimize the structure of a beam part, improve the stress of the structure and meet the elevation and flood discharge requirements of a forward connection bridgehead road. Which comprises beam parts arranged on river banks on two sides, two longitudinal ends of each beam part are fixedly connected with a bearing platform below the beam part through a supporting structure, and is characterized in that the beam parts arch upwards in a midspan mode, the middle parts are connected through circular curves, the end parts are connected through concave curves, and the beam ends are fixedly connected with the supporting structures; the supporting structure is a combined support composed of a bevel edge wall and a vertical side wall, the center line of the bevel edge wall on the top face of the bearing platform does not intersect with the center line of the vertical side wall, and the lower end of the outer side of the bevel edge wall is arranged to be a vertical side.
一种微拱薄梁门式刚构桥梁，以优化梁部构造，改善结构受力，满足顺接桥头道路标高和行洪要求。包括设置于两侧河岸的梁部，该梁部的纵向两端通过支撑结构与其下方的承台固结，其特征是：所述梁部跨中上拱，中部采用圆曲线，端部采用凹曲线相连，梁端与支撑结构固结；所述支撑结构为由斜边墙、竖边墙构成的组合支承，承台顶面处斜边墙中心线与竖边墙竖墙中心线不相交，且斜边墙外侧下端设置成竖直边。
