新沙哈·阿曼纳特大桥主桥为(115+3×200+115)m连续预应力箱梁矮塔斜拉桥。主梁采用带箱内斜撑的单箱单室薄壁箱梁;斜拉索采用单索面布置,在桥塔处从上塔柱转向鞍管穿过桥塔,两端锚固在主梁顶板与斜撑交汇处;桥塔由底座、下塔柱和上塔柱构成。上部结构箱梁0号块及1号块均在支架上现浇施工,墩顶临时固结形成T构,其它节段采用三角挂篮对称悬臂浇筑施工,合龙段采用合龙吊架施工,箱梁边跨现浇段采用支架现浇施工;桥塔采用定型钢模分次浇注施工;为便于箱梁现浇挂篮的安装,斜拉索施工滞后箱梁施工1个节段。该桥的结构特点最大限度地发挥了矮塔斜拉桥的工程经济性。
The main bridge of Xinshaha Armanate Bridge is a short cable-stayed bridge with (115 + 3 × 200 + 115) m continuous prestressed box girders. The main girder adopts the single box single-chamber thin-walled box girder with bracing inside the box; the stay cable is arranged in a single cable plane, the saddle pipe passes through the pylons from the upper pylons to the pylons, and both ends are anchored to the girder top plate And diagonal cross junction; bridge tower from the base, the lower tower and the upper tower form. The superstructure box girder No. 0 block and No. 1 block are cast-in-place on the support. The pier top is temporarily consolidated to form a T-structure. The other sections are constructed with triangular hanging basket symmetrical cantilever construction. Cast-in-place construction of side-by-side cast-in-place construction is adopted; the bridge tower is constructed by sub-pouring of stereotyped steel molds; in order to facilitate the installation of the in-situ hanging box of box girder, The structural characteristics of the bridge to maximize the dwarf cable-stayed bridge engineering economy.
