本文通过对错列桁架体系受力性能的分析，第一次明确地提出了体系节点构造应该根据平面桁架形式来确定的原则。 |
| 10. | The cfst x - type arches improve the lateral stability by sloping the arc ribs , so it is ofen used in the designs of cfst arch bridge with small ratio of the width to the span . tongwamen bridge is a half - through cfst arch bridge , its span is 238m , and the width of its roadway is 10m , so the truss ribs in - plane is sloped into x - shapc to improve its lateral stability . as the cfst x - type arches with longest span all over the country presently , the design of tongwamen bridge can be used for reference of adopting cfst x - type arches in the design of arch bridges with small ratio of the width to the span
钢管混凝土x型肋拱桥是一种利用拱肋侧倾来提高其横向整体稳定性的桥型，在宽跨比较小的钢管混凝土拱桥设计中应用较多。浙江铜瓦门大桥是一座中承式钢管混凝土无铰拱桥，跨径238m ，桥宽10m ，拱肋为平面桁架形式，所以采用了x型拱肋以提高其横向稳定性。作为国内目前跨径最大的钢管混凝土提篮拱桥，该桥的建成对我国今后长大跨径小宽跨比钢管混凝土拱桥采用提篮拱具有借鉴意义。 |
