摘要
公路建设标准化和2014版规范修编对预制桥梁通用设计提出了新要求。广东省公路装配式预制T梁是首次系统编制和发布、用于全省高速公路建设的省级通用设计,在构件类别、桥宽、预制梁标准截面、安全性、耐久性等方面均有较大地改进和创新。介绍了广东省公路装配式预制T梁采用的主要技术指标和设计参数,总结了其横断面布置及预制截面等新型构造,结构标准化、结构安全性、结构经济性及相关专题研究等方面的创新成果,供使用时参考。
Standardization of highway construction and the specification 2014 version have put forward new requirements for the standard design of prefabricated bridges.The standards design of prefabricated prestressed T-beam for highway bridges in Guangdong Province are the 1st provincial level standards design organized systematically and publicized by local transport administration.There are significant improvement and innovation in terms of structural member type,bridge width,typical cross section,safety,and durability etc.In this paper,the main technical indexes and design parameters are presented.The innovation achievements are concluded from the perspectives of new prefabricated T-beam structural layout,standardizations,structure safety,cost economy,and many special research topics etc.,which may be referred in future.
