鋼波紋涵管也叫波(bo)(bo)紋管(guan)(guan)(guan)(guan)涵(han)(han)(han)，是指(zhi)鋪埋(mai)在(zai)公路(lu)、鐵路(lu)路(lu)下的涵(han)(han)(han)洞用的螺(luo)紋波(bo)(bo)紋管(guan)(guan)(guan)(guan)，它是由波(bo)(bo)形(xing)鋼板(ban)卷制(zhi)成(cheng)或(huo)用波(bo)(bo)形(xing)鋼片(pian)組拼成(cheng)的圓形(xing)鋼結構管(guan)(guan)(guan)(guan)。金屬(shu)波(bo)(bo)紋管(guan)(guan)(guan)(guan)涵(han)(han)(han)的波(bo)(bo)紋結構可(ke)使涵(han)(han)(han)洞路(lu)面(mian)受(shou)力合理(li)，荷載分(fen)布均勻，并具有一定(ding)的抗變形(xing)能力，能解決北方寒冷地(di)區（霜凍）對橋梁和管(guan)(guan)(guan)(guan)涵(han)(han)(han)砼結構的破壞(huai)問題；使路(lu)表(biao)面(mian)沒有伸縮(suo)縫，提高行車(che)舒(shu)適(shi)性；有利(li)于改善軟土地(di)基結構與(yu)路(lu)堤交(jiao)界處的“錯臺(tai)”現象，提高行車(che)安全性。波(bo)(bo)紋管(guan)(guan)(guan)(guan)涵(han)(han)(han)的工(gong)后營(ying)運、養護(hu)成(cheng)本低(di)，工(gong)程實際造價也低(di)于同類(lei)跨徑的橋梁、涵(han)(han)(han)洞。鋼波(bo)(bo)紋涵(han)(han)(han)管(guan)(guan)(guan)(guan)進出口(kou)也可(ke)按照邊坡(po)比例做成(cheng)斜口(kou)，加工(gong)波(bo)(bo)紋管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)徑范圍(wei)0．5～8 m，管(guan)(guan)(guan)(guan)壁厚度(du)為3 mm～7 mm，能夠滿足填(tian)土0．5 ～40 m厚的需要。
