多跨斜交现浇箱梁支座布置方式分析

Analysis of support arrangement of multi span skew cast-in-place box girder

通过对斜交现浇箱梁的研究分析,斜交箱梁如何正确布置支座是比较复杂的问题,此种复杂结构的支座布置及支反力求解应采用空间模型计算,合理支座布置不仅保证桥梁结构安全,还能降低造价、减轻后期桥梁养护工作。

Through the research and analysis of skew cast-in-place box girder,how to correctly arrange the support of skew boxgirder is a relatively complex problem.The support arrangement and reaction of the complex structure should be calculated by spa-tial model.Reasonable support arrangement not only ensures the safety of bridge structure,but also reduces the cost and reducesthe maintenance work of bridge in the later stage.
