【摘要】：坦桑尼亚基甘博尼大桥主桥为双塔单索面预应力混凝土斜拉桥,跨径布置为(40+60+200+60+40)m,主梁采用预应力混凝土单箱三室闭合截面,桥塔为单柱式空心八边形截面,塔高55m,桥塔墩为矩形空心薄壁墩,塔梁固结、塔墩分离。该桥斜拉索采用80~160股平行钢绞线,设计最大拉力13 910kN;主梁斜拉索锚固处设置施加预应力的横向肋板;索塔锚固区采用双J形环向预应力;边墩及辅助墩支座采用独特的大吨位拉压支座;边墩及辅助墩承台采用空心框架结构。采用桥梁结构设计系统SCDS2011进行结构计算分析,结果表明结构受力性能均满足规范要求。
[Abstract]:The main bridge of Kigamboni Bridge in Tanzania is a double-tower single-cable plane prestressed concrete cable-stayed bridge with span arrangement of (40 60 200 60 40) m. The main beam is composed of prestressed concrete single box and three rooms closed section, and the tower is a single column hollow octagonal section. Tower height 55 m, bridge tower pier is rectangular hollow thin-walled pier, tower beam consolidation, tower pier separation. The cable-stayed cable of the bridge is 80,160 parallel strands, the maximum tensile force is 13 910kN, the main girder cable Anchorage is provided with prestressed transverse ribbed slab, the cable tower Anchorage zone adopts double J shape circumferential prestressing force, and the cable tower anchoring area adopts double J ring prestressing force. The side pier and auxiliary pier support adopt the special large tonnage pull-compression support, and the side pier and auxiliary pier cap adopt hollow frame structure. The bridge structure design system SCDS 2011 is used to calculate and analyze the structure. The results show that the mechanical performance of the structure meets the requirements of the code.
