摘要
以某大桥方案为例,采用ICEM和FLUENT建立了定常和非定常模型,分析并得到了其空气动力学参数。叙述桥梁抗风设计的原理及具体流程,有助于类似工程在方案及初步设计阶段快速判定桥梁的抗风性能。
Taking a bridge scheme as an example,the ICEM and FLUENT are used to establish the steady and unsteady models for the analysis and obtaining of its air dynamics parameters.The article describes the principle and detailed process of bridge wind resistance design,which can be referred for the quick determination of bridge wind resistance performance of the similar projects in the scheme and preliminary design stages.
