鋼波紋涵管也叫波(bo)(bo)紋管(guan)(guan)(guan)涵，是(shi)指鋪埋(mai)在公路、鐵(tie)路路下的涵洞用的螺紋波(bo)(bo)紋管(guan)(guan)(guan)，它是(shi)由(you)波(bo)(bo)形(xing)鋼(gang)(gang)板卷制(zhi)成(cheng)(cheng)或(huo)用波(bo)(bo)形(xing)鋼(gang)(gang)片(pian)組拼成(cheng)(cheng)的圓形(xing)鋼(gang)(gang)結構(gou)管(guan)(guan)(guan)。金屬波(bo)(bo)紋管(guan)(guan)(guan)涵的波(bo)(bo)紋結構(gou)可(ke)(ke)使涵洞路面受力合(he)理，荷載分布均勻，并具有一定的抗變形(xing)能(neng)力，能(neng)解決北方(fang)寒冷地區(qu)（霜凍）對橋(qiao)梁(liang)和管(guan)(guan)(guan)涵砼結構(gou)的破壞問題；使路表面沒有伸縮縫，提(ti)(ti)高行車舒(shu)適性；有利于(yu)改善軟土地基(ji)結構(gou)與路堤交界處的“錯臺(tai)”現象，提(ti)(ti)高行車安(an)全性。波(bo)(bo)紋管(guan)(guan)(guan)涵的工后(hou)營運、養護成(cheng)(cheng)本低，工程實際造(zao)價也低于(yu)同類(lei)跨(kua)徑(jing)的橋(qiao)梁(liang)、涵洞。鋼(gang)(gang)波(bo)(bo)紋涵管(guan)(guan)(guan)進(jin)出口也可(ke)(ke)按照(zhao)邊坡比例做成(cheng)(cheng)斜口，加工波(bo)(bo)紋管(guan)(guan)(guan)管(guan)(guan)(guan)徑(jing)范圍(wei)0．5～8 m，管(guan)(guan)(guan)壁(bi)厚度為3 mm～7 mm，能(neng)夠滿(man)足填土0．5 ～40 m厚的需要。
