公路Ⅰ级和Ⅱ级荷载在曲线连续梁桥中应用分析

The application analysis on highway Ⅰ and Ⅱ load in curve continuous beam

对一系列不同半径的曲线连续梁桥进行了设计验算,并对计算结果作了对比分析,利用空间梁单元程序Midas,分别施加汽超—20、汽—20、公路Ⅰ级、公路Ⅱ级车道荷载,探讨了活载对于曲线梁桥应用的合理性,分析结果为同类桥梁设计提供了参考。

This paper made design checking to a series of curve continuous beam bridge with different radius,and compared and analyzed the calculation results,using spatial beam element program Midas,respectively applied steam ultra-20,steam-20,highway level Ⅰ,highway Ⅱ lane load,discussed the application rationality of load to curve beam bridge,the results provided reference for similar bridges design.
