摘要：在高速公路刚构桥墩台设计与施工中，箱型薄壁墩与双薄壁墩因其施工简便，经济实用等特点而被广泛采用。本文基于ANSYS有限元软件分别对这两种结构形式进行了建模分析，以期通过对比他们的力学性能来优化设计方案，选取合理的设计参数，进一步指导施工。通过分析对比在荷载作用下最不利截面上应力和位移的变化情况，总结出同一形式薄壁墩在同一截面与不同截面下应力的变化规律，以及不同横截面积情况下桥墩顶端位移的变化规律。在考虑两种形式的薄壁墩受力性能的的基础上，给出了优化箱型薄壁墩薄壁厚度的选取范围，并针对双薄壁墩提出增加横向连接的建议。 Abstract: During the construction of rigid frame piers of expressways, box thin-walled piers and double thin-walled piers are widely used because of their lots of characteristic, such as simple construction, economy, practicality and so on. ANSYS finite element software is used to model and analyze the two types of structures, in order to optimize the design scheme by comparing their mechanical properties, and select reasonable design parameters, and guide the construction. By analyzing and comparing the changes of stress and displacement on the most dangerous cross-section under the load, the law of stress variation of the same type of thin-walled pier under the same cross-section and different cross-section are summarized. On the basis of considering the mechanical properties of two types of thin-walled piers, the thin-walled thickness of box thin-walled piers is given, and suggestions for adding the lateral connection of double thin-walled piers are put forward.
