摘要
介绍了马蹄山1号大桥的桥型构造特点与结构设计思想,完成了主桥纵向受力计算和桥墩的稳定性计算分析。结果表明,此桥的主梁截面抗裂验算、抗压验算、承载能力强度等均满足规范要求;成桥阶段活载稳定安全系数λ=19.6,该桥有较高的稳定性。
The structure characteristics and design idea of main beidge of Horseshoe Hill No.1 bridge were introduced.On that basis,the longitudinal mechanical calculation of the bridge and stability calculation of the piers were completed.The results show that crack resistance,compressive resistance and carrying capacity of the bridge girder crack section meet the requirements of China current code.The stability factor of the completionin stage under the live load is 19.6 which show that the bridge has higher stability.
