摘要:为了研究得到跨座式单轨交通先简支后刚构体系桥梁在桥墩截面固定的情况下的合理墩高及墩身抗推刚度限值,建立了(5×24)m先简支后刚构体系的分析模型。通过研究不同墩高对墩身受力的影响,得到了施工阶段及运营阶段墩身受力随墩高变化的趋势,首次拟定了跨座式单轨交通先简支后刚构体系的合理墩高及抗推刚度限值。

The research on the appropriate pier height setting of the straddle monorail transit simply supported to rigid frame system
Abstract:In this paper, the finite element modal of 5×24m simply supported to rigid frame system is established to get the pier height and anti push rigidity limits. The force changing trends of pier with the height changing in the stage of construction and operation are got by studying the influence of different heights for the stress of the pier, the pier height and anti push rigidity limits of 5×24m simply supported to rigid frame system are firstly got according to requirements of the design specification .
Keywords: Straddle monorail transit Simply supported to rigid frame system Appropriate pier height Anti push rigidity
