钢结构系杆拱桥梁施工方法研究

Research on Construction Method of Steel Tie-Arch Bridge

随着时代和社会的飞速发展,各类桥梁结构层出不穷,其中系杆拱桥就是被广泛采用的一种桥梁结构形式。从本质上来说,系杆拱桥也是一种拱桥,只不过拱桥的形式比较特殊,传统的直杆被斜杆所取代,与拱桥本身的结构组成了尼尔森艺术,在施工过程中设置了专门的超静定结构,即使系杆拱桥的墩台结构出现沉降现象,与传统的拱桥相比也更加稳定和安全。

With the rapid development of the times and society,various bridge structures emerge one after another,among which tied arch bridge is a widely used bridge structure.In essence,the tied arch bridge is also a kind of arch bridge,but the form of the arch bridge is special.The traditional straight rods are replaced by inclined rods,and the structure of the arch bridge itself constitutes Nelson Art.The statically determinate structure is more stable and safer than traditional arch bridges,even if the pier and abutment structures of tied arch bridges appear to settle.
