近年来,在预应力混凝土梁桥与斜拉桥之间出现了一种新的桥梁结构形式——矮塔斜拉桥,也称部分斜拉桥,在日本、菲律宾、瑞士、韩国及我国得以应用,尤其是日本大量的建造矮塔斜拉桥,使这种桥型得以发展起来。文章首先回顾矮塔斜拉桥的发展历程,然后简要介绍这种桥型的受力特点及构造,并与梁桥与斜拉桥构造进行对比,总结结构参数的取值范围,通过与梁桥与斜拉桥的相关参数比较,更直观的反映这种桥型设计时要注意的问题。
In recent years, a new type of bridge structure has emerged between prestressed concrete girder bridges and cable-stayed bridges - dwarf cable-stayed bridges, also known as partial cable-stayed bridges, which are available in Japan, the Philippines, Switzerland, Korea and our country Applications, especially the large number of dwarf cable-stayed bridges built in Japan, have enabled the bridge to develop. The article first reviews the development history of the short pylon cable-stayed bridge, and then briefly introduces the force characteristics and the structure of the bridge, compares with the structures of the bridge and the cable-stayed bridge, summarizes the range of the structural parameters, Compared with the relevant parameters of cable-stayed bridge, more intuitively reflect the design of this bridge should pay attention to the problem.
