鋼波紋涵管也(ye)叫波(bo)紋(wen)管(guan)(guan)涵(han)(han)(han)，是(shi)指(zhi)鋪埋在公路、鐵路路下(xia)的(de)(de)涵(han)(han)(han)洞(dong)用(yong)的(de)(de)螺紋(wen)波(bo)紋(wen)管(guan)(guan)，它是(shi)由波(bo)形(xing)鋼(gang)板卷制成(cheng)或(huo)用(yong)波(bo)形(xing)鋼(gang)片(pian)組拼成(cheng)的(de)(de)圓(yuan)形(xing)鋼(gang)結構(gou)管(guan)(guan)。金屬(shu)波(bo)紋(wen)管(guan)(guan)涵(han)(han)(han)的(de)(de)波(bo)紋(wen)結構(gou)可(ke)使(shi)(shi)涵(han)(han)(han)洞(dong)路面受力合理，荷載分布均勻(yun)，并(bing)具有(you)一定的(de)(de)抗(kang)變形(xing)能(neng)力，能(neng)解決北(bei)方寒冷(leng)地(di)(di)區（霜(shuang)凍）對(dui)橋梁(liang)和管(guan)(guan)涵(han)(han)(han)砼結構(gou)的(de)(de)破壞(huai)問題；使(shi)(shi)路表(biao)面沒(mei)有(you)伸縮縫(feng)，提高(gao)行車舒(shu)適(shi)性；有(you)利于改善軟土(tu)地(di)(di)基結構(gou)與路堤交(jiao)界處的(de)(de)“錯臺”現象，提高(gao)行車安全性。波(bo)紋(wen)管(guan)(guan)涵(han)(han)(han)的(de)(de)工后營運、養(yang)護成(cheng)本(ben)低，工程(cheng)實際(ji)造價也(ye)低于同類跨徑的(de)(de)橋梁(liang)、涵(han)(han)(han)洞(dong)。鋼(gang)波(bo)紋(wen)涵(han)(han)(han)管(guan)(guan)進(jin)出(chu)口也(ye)可(ke)按(an)照邊(bian)坡比例做成(cheng)斜口，加工波(bo)紋(wen)管(guan)(guan)管(guan)(guan)徑范圍0．5～8 m，管(guan)(guan)壁厚度為3 mm～7 mm，能(neng)夠滿足填(tian)土(tu)0．5 ～40 m厚的(de)(de)需要。
