摘要
以某特大桥现浇连续箱梁施工工程为例,结合现浇连续箱梁施工经验及地勘水文资料,对支架进行设计,并用Midas Civil软件建立模型进行验算。结果表明:运用计算模型进行受力验算,结果证实了设计的合理性及支架结构的可靠性,可为同一类型支架结构设计提供设计依据和实践经验。
In this paper,taking the cast-in-place continuous box girder construction project of a super large bridge as an example,combined with the construction experience of cast-in-place continuous box girder and geological and hydrological data,the support is designed,and the model is established by Midas Civil software for checking calculation.The results show that:using the calculation model to check the stress,the checking results confirm the reliability of the support structure and the rationality of the design,which can provide theoretical basis and practical experience for the design of the same type of support structure.
