【摘要】：龙江大桥主桥为主跨1 196m的双塔单跨简支钢箱加劲梁悬索桥,大桥主缆分跨布置为320m+1 196m+320m。加劲梁采用流线型扁平钢箱结构,桥面宽33.5m;两岸桥塔采用门形混凝土结构,塔底设钻孔灌注桩基础;保山岸桥塔总高169.688m,腾冲岸桥塔总高129.703m;两岸采用重力式锚碇和扩大基础;主缆采用强度1 770MPa、鐖5.25mm的镀锌平行钢丝索股;吊索采用强度1 670MPa、鐖52mm的钢芯钢丝绳。采用ANSYS计算软件,对主桥结构进行了总体静力计算,结果表明桥梁各主要构件的最不利内力及位移均满足规范要求,为该桥的设计提供了依据。
[Abstract]:The main bridge of Longjiang Bridge is a steel box stiffened girder suspension bridge with two towers and one span with a main span of 1196m. The main cable span of the bridge is 320m 1 196m 320m. The stiffening beam adopts streamlined flat steel box structure, the width of bridge deck is 33.5 m, the bridge tower is portal concrete structure, the bottom of the tower is filled with bored pile foundation, the total height of Baoshan bank bridge tower is 169.688m, the total height of Tengchong bank bridge tower is 129.703m. Gravity Anchorage and enlarged foundation are adopted on both sides; main cable is zinc-plated parallel wire strands of 5.25mm with strength of 1 770 MPA; sling is steel wire rope with strength of 1 670 MPA and core of 52mm. The overall static calculation of the main bridge structure is carried out by using ANSYS software. The results show that the most unfavorable internal forces and displacements of the main components of the bridge all meet the requirements of the code, which provides the basis for the design of the bridge.
