摘要
近年来由于城市立交桥建设的需要,曲线梁桥结构在我国已被广泛采用。小半径曲线梁桥的设计计算比较复杂,但通过有限元分析计算,可以较为准确地掌握其结构的受力状况。针对其不同于直线梁的受力特点,采用相应的有效措施,是可以设计出较为可靠且经济适用的曲线梁桥的。
For the demand of city cloverleaf junction developments in recent years, curve beam bridge structure has been widely adopted in China. Though the design calculations are complex for the curve beam bridge with a small radius, it can get correctly the stress conditions of the structure through finite-element analysis calculations. In view of the stress characteristics different from these of linear beam, some effective measures can be taken to assure the design of reliable and economical curve beam bridge.
