观音沙特大桥上部构造设计验算与长期跟踪监测

介绍了观音沙特大桥上部构造T构设计。采用新、旧规范对T构进行验算,并在营运期长期跟踪桥梁病害及挠度变化,力图从结构设计及营运期产生的病害中找到相关性,从根本上对病害进行处治,也对设计成果跟踪反馈,为同类桥型深化设计提供经验。

Design, Calculation and Long- term Comprehensive Monitoring for Superstructure of Guanyinsha Special Large Bridge

In this paper, the design of T-structure superstructure of Guanyinsha Special Large Bridge has been introduced, check calculation for the T-structure with both old and new specifications has been carried out, and long-term monitoring for diseases and deflection changes has been conducted during its operation, in order to try to find out the interrelations between the structural design and the disease, so treatment of disease from the beginning can be achieved, which can also be used as tracking and feedback for the design and provide basis for deepened design of similar bridges.
