鋼波紋涵管也叫(jiao)波紋(wen)(wen)管(guan)(guan)涵(han)(han)，是指鋪埋在公路(lu)、鐵路(lu)路(lu)下的(de)涵(han)(han)洞(dong)(dong)(dong)用(yong)(yong)的(de)螺紋(wen)(wen)波紋(wen)(wen)管(guan)(guan)，它是由波形鋼板卷制成(cheng)(cheng)或(huo)用(yong)(yong)波形鋼片組拼(pin)成(cheng)(cheng)的(de)圓(yuan)形鋼結構(gou)管(guan)(guan)。金屬波紋(wen)(wen)管(guan)(guan)涵(han)(han)的(de)波紋(wen)(wen)結構(gou)可使(shi)涵(han)(han)洞(dong)(dong)(dong)路(lu)面(mian)受力合理(li)，荷載分布(bu)均勻，并具有(you)一定(ding)的(de)抗變形能力，能解決(jue)北方寒冷地區（霜(shuang)凍）對橋梁和管(guan)(guan)涵(han)(han)砼結構(gou)的(de)破壞問(wen)題；使(shi)路(lu)表面(mian)沒(mei)有(you)伸縮縫(feng)，提(ti)(ti)高行(xing)車(che)舒適性(xing)；有(you)利(li)于改善軟土(tu)地基結構(gou)與路(lu)堤交(jiao)界處的(de)“錯臺”現象(xiang)，提(ti)(ti)高行(xing)車(che)安(an)全(quan)性(xing)。波紋(wen)(wen)管(guan)(guan)涵(han)(han)的(de)工后營運(yun)、養護成(cheng)(cheng)本低(di)(di)，工程實(shi)際造價也低(di)(di)于同(tong)類跨徑(jing)的(de)橋梁、涵(han)(han)洞(dong)(dong)(dong)。鋼波紋(wen)(wen)涵(han)(han)管(guan)(guan)進出口(kou)也可按照邊坡(po)比(bi)例做成(cheng)(cheng)斜口(kou)，加工波紋(wen)(wen)管(guan)(guan)管(guan)(guan)徑(jing)范圍0．5～8 m，管(guan)(guan)壁厚度為3 mm～7 mm，能夠滿足填土(tu)0．5 ～40 m厚的(de)需要。
