混凝土斜拉桥二次调索顺序优化设计

文中以广州沙湾特大桥作为工程背景,对混凝土斜拉桥成桥后全桥二次调索顺序进行优化设计.沙湾特大桥二次调索顺序优化设计以主粱上下缘应力、斜拉索应力以及施工工期等为控制原则,对几种不同的调索方案进行优化设计.考虑现场施工设备所造成的限制,最终选定按照从短索到长索的顺序,先在北侧索塔调3对索,再南侧索塔调3对索的交叉调索方案.

Optimization Design of Making the Second Adjustment of Cable Force of Concrete Cable-stayed Bridge

With the background of Shawan bridge which located in Guangzhou,this paper makes the second cable force adjustment optimization design of the concrete cable-stayed bridge.For Shawan bridge,the stress of the upper and lower edge of the main beam,the stress of the cable and the construction period is as the control principle of the optimization design for cable force adjustment.Considering the constraint of the site construction equipment,we select the scheme which is in accordance with the order from the sho...
