太原市火炬桥的结构静力分析

Integral Structural Static Analysis of Taiyuan Huoju Bridge

太原市机场路火炬桥主桥为单塔三柱式的独塔斜拉桥。主梁为钢+混凝土的混合梁形式,混凝土梁段为单索面.钢梁段为双索面。针对其结构特点和技术标准,设计制定了施_T阶段的施工方案和施工流程,明确了使用阶段各典型受力状况。根据该桥的结构特点应用结构分析程序对施工和使用阶段进行了总体结构静力分析.通过分析结果验证了施T方案的可行性和结构设计的安全性,并对施工阶段的操作提出了合理的建议。

The main bridge of Taiyuan airport highway-Huoju Bridge is a single pylon with 3-columns cable stayed bridge.The main girder adopts the combination style of steel box girder and concrete box girder,the concrete girder span is supported with single plane cable while the steel girder span is supported with double plane cable.According to the structural characteristics and technical standard,the design established construction scheme and the construction stage,and gained all force states during the service period. According to its structural characteristics,the integral structural static analysis are simulated with program following the construction stage and service stage.The results of the analysis prove the feasibility of construction project and the safty of structural design and some advice are also brought for the construction stage.
