结合四川涪江五桥斜拉桥主塔钢锚梁施工工艺,单跨布置了24对斜拉索,采用“钢锚梁+钢牛腿”的锚固形式介绍钢锚梁施工测量技术,保证实际结构在逐段施工过程中的受力和变形始终处于可控、安全及合理的范围内,并且由这些施工状态逐步演化到成桥后,结构内力和线形均符合设计要求,并且与理论期望值的误差最小。斜拉桥主塔钢锚梁安装的精确定位测量是斜拉桥的关键技术之一。
Combined with the construction technology of the steel anchor beam of the main tower of the Fifth Bridge of Fujiang River in Sichuan, 24 pairs of stay cables were arranged in single span and the anchoring method of steel anchor with steel anchor was introduced. It is ensured that the force and deformation of the actual structure in the process of section-by-section construction are always within the controllable, safe and reasonable range. After the gradual evolvement of these construction stages to the completion of the bridge, the structural internal forces and line shapes meet the design requirements, The minimum expected error. Cable-stayed Bridge Positioning of steel anchor beam installation is one of the key technologies of cable-stayed bridge.
