为研究水平荷载作用下不同横断面形式的桥梁墩台的受力性能,建立了横断面面积相同、形状不同的桥梁墩台的有限元模型,并进行相应的应力和位移数值分析。结果表明,在相同截面面积和外荷载作用下,不同横断面形式的墩台底部第一主应力与墩台顶部最大位移均呈规律性变化。在此基础上,文章对不同截面形式墩台的受力性能的优劣性进行了分析。研究结果对于桥梁墩台结构构造的确定,具有一定的参考价值。
為研究水平荷載作用下不同橫斷麵形式的橋樑墩檯的受力性能,建立瞭橫斷麵麵積相同、形狀不同的橋樑墩檯的有限元模型,併進行相應的應力和位移數值分析。結果錶明,在相同截麵麵積和外荷載作用下,不同橫斷麵形式的墩檯底部第一主應力與墩檯頂部最大位移均呈規律性變化。在此基礎上,文章對不同截麵形式墩檯的受力性能的優劣性進行瞭分析。研究結果對于橋樑墩檯結構構造的確定,具有一定的參攷價值。

For the study of the mechanical performance of bridge piers with different cross-section forms under the action of horizontal load ,the finite element models of bridge pier with same area but different shapes of cross-section were estab-lished ,and the corresponding numerical analysis of stress and displacement was carried out .The results showed that ,un-der the same load some performances of the bridge piers with same area but different cross-sections changed regularly . The performances were the principal stress of the pier bottom and the maximum displacement of the pier top .On this ba-sis ,the advantages and disadvantages of piers with different cross-section forms were analyzed in the article .The results have a certain referential value to the determination of bridge pier structures .
