摘要
福州市二环路总院门口高架桥为"U"形匝道桥,处于曲线半径27.5m的圆弧上。介绍了其上部连续曲线箱梁的设计特点,阐述了小半径钢筋混凝土连续曲线箱梁的结构计算、配筋、构造等。该桥经过一年多的运营荷载,特别是环境荷载的考验,至今未出现设计时最为担心的"爬坡"、"梁端偏移"等结构稳定性问题。
The curve bridge with "U"shape across No2 ring road in Fuzhou is a ramp bridge,which semidiameter of continuous curve box girder is of 27.5 meters.The design characteristics,structural calculation,arrangment of reinforcements and its construction is introducted. After operating more than a year, the stability of the structure is in good condition.
