Abstract
This paper takes the (60+92+60) m continuous rigid frame box beam bridge as an example, which is locate on a horizontal curve with radius of 300 m in project stage 3 of Changchun Light Rail. The study on the design for this kind of bridge with small radius curve and long span were carried out, by focusing on the characteristics of this kinds of bridge, such as the complex structure stresses, coupling effective of bending moment and shearing force and torsion moment, high standards of anti-torsion ability of section, difficult conditions of design and construction and so on. The study results showed that the usage of this kind of beam bridge with small radius curve and long span under the loads of the light rail is reasonable, feasible, realizable and worth being popularized.关键词
