2 . a new design and construction method different from the traditional way was used in jinma bridge . when cantilever the main girder of the cable - stayed structure , the longitudinal pre - stressed reinforcements are not tensioned at once
2 、金马大桥在斜拉桥设计和施工中采用一种与传统斜拉桥设计和施工不同的新方法，即悬臂浇筑斜拉桥主梁时采用无纵向预应力筋的做法。
This new erection procedure is compared with the conventional way from the reasonability , convenience and economic aspects . the results obtained from the calculating data state that cantilevering the main girder without tensioning the longitudinal pre - stressed reinforcements is a better way for establishing the cable - stayed bridge
本文把这种方法与传统方法在受力合理性、施工方便程度和经济性方面做了比较分析，并结合整体静力计算说明悬臂浇筑斜拉桥主梁时不张拉纵向预应力筋这一方法的可取之处。
