摘要
以某高速公路一座五跨一联先简支后连续柱式墩梁桥为例,基于墩柱计算长度理论公式并结合Midas分析软件,对比分析了地基土比例系数m、墩柱高以及分联设计对柱式墩顺桥向计算长度系数的影响规律。分析结果表明:地基土比例系数m对矮墩计算长度系数影响大,对高墩影响较小;对于多跨一联桥梁,高墩计算长度系数小,矮墩计算长度系数大;一联孔数的减小对矮墩计算长度系数影响小,对高墩影响较大,同时,在一联孔数相同时,不同的分联方式也会影响到墩柱的计算长度系数。
Taking a highway five-span one-union first simply-supported and then continuous-column pier bridge as an example, based on the theoretical formula of pier column calculation length, and combined with Midas analysis software, this paper compared and analyzed the influence law of the foundation soil proportional coefficient m, pier column height and joint design on the column pier along the bridge of the calculated length coefficient.
