跨沪蓉高速转体桥梁的称重试验技术

Weighing Test Technology of Swivel Bridge Crossing the Shanghai-Chengdu Expressway

称重试验时转体施工中的关键工序,为后续确定是否配重提供最直接数据支撑。结合大明路跨沪蓉高速公路桥梁转体施工的称重试验,分析试验实施方法及步骤,获得不平衡力矩、偏心距、摩阻力矩及摩阻系数等参数,指导了转体施工。

Weighing test is the key process of swivel construction,which provides the direct data of counterweight.The weighing test of the Daming Road Bridge over the Shanghai-Chendu Expressway obtains the unbalanced moment,eccentricity,friction torque and friction coefficient etc.It guides the swivel construction.
