摘要
武汉至九江客运专线铁路西南下行联络线特大桥主桥采用(82+154+88)m矮塔斜拉桥跨越3条既有铁路。通过对矮塔斜拉桥结构形式、主梁构造、桥塔及斜拉索锚固型式、施工方法等进行设计研究,得出如下结论:桥梁满足功能性要求;新型抗滑鞍座能够起到有效锚固作用;转体施工降低了对铁路运营的干扰;桥梁各项指标均满足相关规范的要求。
The main part of the bridge on Wuhan-Jiujiang dedicated passenger railway adopts（82＋154＋88） m extradosed cable-stayed bridge to cross three existing railways. This paper analyzes the bridge structure type,girder structure,bridge tower and cable anchorage form and construction method. The research draws the following conclusions： this extradosed cable-stayed bridge meets the functional requirements,a new type of anti-sliding saddle plays an effective role in anchoring towers and cables; the horizontal rotation construction method adopted reduces the disturbance to existing railways and all indicators satisfy the requirements of standards.
