鋼波紋涵管也叫波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)涵(han)(han)，是指鋪埋在(zai)公路(lu)、鐵路(lu)路(lu)下的(de)涵(han)(han)洞(dong)用的(de)螺紋(wen)(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)，它是由波(bo)(bo)(bo)形鋼板卷制成(cheng)(cheng)或用波(bo)(bo)(bo)形鋼片組拼成(cheng)(cheng)的(de)圓形鋼結構(gou)(gou)管(guan)。金(jin)屬波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)涵(han)(han)的(de)波(bo)(bo)(bo)紋(wen)(wen)(wen)結構(gou)(gou)可使(shi)涵(han)(han)洞(dong)路(lu)面受力(li)合理，荷載(zai)分布均勻(yun)，并具(ju)有(you)(you)(you)一定的(de)抗變形能力(li)，能解決北方寒冷地區(qu)（霜(shuang)凍）對橋梁和管(guan)涵(han)(han)砼(tong)結構(gou)(gou)的(de)破壞(huai)問題；使(shi)路(lu)表面沒有(you)(you)(you)伸縮縫，提高行車舒適性(xing)(xing)；有(you)(you)(you)利于改善軟(ruan)土(tu)地基結構(gou)(gou)與路(lu)堤交界處的(de)“錯臺”現(xian)象，提高行車安(an)全性(xing)(xing)。波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)涵(han)(han)的(de)工后營運、養護(hu)成(cheng)(cheng)本(ben)低，工程(cheng)實際造價也低于同(tong)類跨徑的(de)橋梁、涵(han)(han)洞(dong)。鋼波(bo)(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)管(guan)進(jin)出口也可按照邊坡比(bi)例做成(cheng)(cheng)斜口，加(jia)工波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)管(guan)徑范(fan)圍(wei)0．5～8 m，管(guan)壁厚(hou)度為3 mm～7 mm，能夠滿足填土(tu)0．5 ～40 m厚(hou)的(de)需要。
