垂直上彎通橋和垂直下彎通是指在橋梁設計中常用的兩種橋梁形式。它們在橋梁的結構形式和施工方式上存在一定的差異。

垂(chui)直(zhi)下(xia)彎(wan)通(tong)是(shi)指(zhi)橋(qiao)麵(mian)在(zai)兩(liang)端(duan)相(xiang)對(dui)較(jiao)低(di)，中(zhong)間(jian)較(jiao)高(gao)的(de)橋(qiao)梁(liang)形(xing)式(shi)。這(zhe)種(zhong)橋(qiao)梁(liang)形(xing)式(shi)適(shi)用(yong)於(yu)地(di)形(xing)平(ping)坦(tan)的(de)地(di)區(qu)
，可(ke)以(yi)減(jian)小(xiao)橋(qiao)梁(liang)的(de)跨(kua)度(du)，增(zeng)加(jia)橋(qiao)梁(liang)的(de)穩(wen)定(ding)性(xing)和(he)承(cheng)載(zai)能(neng)力(li)。垂(chui)直(zhi)下(xia)彎(wan)通(tong)橋(qiao)在(zai)施(shi)工(gong)過(guo)程(cheng)中(zhong)相(xiang)對(dui)簡(jian)單(dan)
，成(cheng)本(ben)也(ye)相(xiang)對(dui)較(jiao)低(di)。

；如果地形平坦，需要承載較大的荷載
，可以選擇垂直下彎通橋。
