摘　　要：兰墅大桥为国内首座独弯塔斜拉桥,塔向背跨弯曲,受力复杂。该桥采用修正的闭环控制法进行监控,对桥梁结构的应力、位移与索力进行了监测,对施工过程中的误差进行了分析和处理,对该桥的施工安全和质量控制起到了重要作用。Lanshu Bridge is the first curved single tower cable-stayed bridge in China. The tower bend toward the short span, and the stress status is complicated. The bridge was controlled by updated close-loop control method. By monitoring the stresses, displacements, cable forces and analyzing the errors, the control method played an important role in the construction safety and quality control. The method also provides a reference for the similar cable stayed bridges.

关 键 词：斜拉桥 施工控制 修正闭环控制法
