| Abstract: | The main bridge structure of Liuzhou Longtun Road Interchange is a through type simply supported tied steel tube concrete arch bridge with a span of 92.5m. By analyzing the temperature sensitivity of the structural system, this bridge is close to the ultimate span of similar structural forms. This article mainly introduces the structural design and static calculation of the bridge, and analyzes and studies the reasonable arch axis coefficient of the structure |
