鋼波紋涵管也叫波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)，是(shi)指鋪埋在公路(lu)、鐵(tie)路(lu)路(lu)下的涵(han)(han)洞用(yong)的螺(luo)紋(wen)波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)，它是(shi)由(you)波(bo)(bo)(bo)形(xing)鋼板卷制成(cheng)或用(yong)波(bo)(bo)(bo)形(xing)鋼片組拼成(cheng)的圓(yuan)形(xing)鋼結構(gou)管(guan)(guan)(guan)(guan)(guan)。金屬波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)的波(bo)(bo)(bo)紋(wen)結構(gou)可(ke)(ke)使(shi)涵(han)(han)洞路(lu)面受力合(he)理(li)，荷載分(fen)布均勻(yun)，并具有一定的抗變形(xing)能力，能解決北方寒冷(leng)地區（霜凍）對橋(qiao)梁和管(guan)(guan)(guan)(guan)(guan)涵(han)(han)砼結構(gou)的破壞(huai)問(wen)題；使(shi)路(lu)表(biao)面沒有伸縮縫，提高(gao)行車(che)舒適性；有利于(yu)改善軟(ruan)土(tu)(tu)地基結構(gou)與路(lu)堤交界處的“錯臺”現象，提高(gao)行車(che)安全性。波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)的工后(hou)營運、養護成(cheng)本低，工程實際造價(jia)也低于(yu)同類跨徑(jing)的橋(qiao)梁、涵(han)(han)洞。鋼波(bo)(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)(guan)進(jin)出口也可(ke)(ke)按照邊坡比例做成(cheng)斜(xie)口，加工波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)徑(jing)范圍(wei)0．5～8 m，管(guan)(guan)(guan)(guan)(guan)壁厚(hou)度為(wei)3 mm～7 mm，能夠滿足填土(tu)(tu)0．5 ～40 m厚(hou)的需要。
