大跨径钢连续梁桥在国内建成较少,但随着施工技术及架桥设备的不断发展,其安装精度高、施工速度快的特点逐渐显现,是200m左右跨径非常有竞争力的桥型之一。以崇启大桥主跨185m的多跨变截面钢连续梁桥为例,分析和比较了该类桥型的关键设计参数,供设计者参考。 However, with the continuous development of construction technology and bridge equipment, the features of high installation precision and fast construction speed are gradually emerging. It is a very competitive bridge with a span of about 200m One of the type. Taking the multi-span steel continuous beam bridge with 185 m span of main span of ChongQi Bridge as an example, the key design parameters of this type of bridge are analyzed and compared for designers' reference.
