摘 要：在高速公路剛構橋墩臺設計與施工中，箱型薄壁墩與雙薄壁墩因其施工簡便，經濟實用等特點而被廣泛采用。本文基于ANSYS有限元軟件分別對這兩種結構形式進行了建模分析，以期通過對比他們的力學性能來優化設計方案，選取合理的設計參數，進一步指導施工。通過分析對比在荷載作用下最不利截面上應力和位移的變化情況，總結出同一形式薄壁墩在同一截面與不同截面下應力的變化規律，以及不同橫截面積情況下橋墩頂端位移的變化規律。在考慮兩種形式的薄壁墩受力性能的的基礎上，給出了優化箱型薄壁墩薄壁厚度的選取范圍，并針對雙薄壁墩提出增加橫向連接的建議。
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.
