大悬臂倒T盖梁设计要点分析

Key design points analysis of Large cantilever inverted T-cap beam

结合某高架桥设计实例,梳理了大悬臂倒T盖梁柱式墩的总体设计要点,即桥墩布置、桥墩造型和盖梁形式选择。详细分析倒T盖梁每个细部构造的设计思路,并对施工过程、温度梯度和基础变位等不利影响进行分析。

Based on the design example of a viaduct,the main points of the overall design of the large cantilever inverted T-cap beam column pier are sorted out,that is the arrangement of the pier,the shape of the pier and the selection of the form of the cover beam.The design idea of each structure detail of the inverted T-cap beam is analyzed in detail,and the adverse effects of the construction process,temperature gradient and foundation displacement are analyzed.
