鋼波紋涵管也(ye)叫波(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)涵，是指鋪埋(mai)在公路(lu)(lu)、鐵(tie)路(lu)(lu)路(lu)(lu)下(xia)的(de)涵洞(dong)(dong)用的(de)螺紋(wen)波(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)，它是由波(bo)(bo)(bo)(bo)形(xing)(xing)鋼板卷制成或(huo)用波(bo)(bo)(bo)(bo)形(xing)(xing)鋼片組拼成的(de)圓形(xing)(xing)鋼結構(gou)(gou)管(guan)(guan)(guan)(guan)(guan)。金屬波(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)涵的(de)波(bo)(bo)(bo)(bo)紋(wen)結構(gou)(gou)可使(shi)涵洞(dong)(dong)路(lu)(lu)面(mian)受(shou)力(li)合理，荷載分布均勻，并(bing)具有(you)一定的(de)抗(kang)變形(xing)(xing)能力(li)，能解決北(bei)方寒(han)冷地(di)區（霜凍）對橋(qiao)梁和管(guan)(guan)(guan)(guan)(guan)涵砼結構(gou)(gou)的(de)破(po)壞問題；使(shi)路(lu)(lu)表面(mian)沒有(you)伸縮縫，提高行(xing)車舒適性；有(you)利(li)于改善(shan)軟(ruan)土地(di)基結構(gou)(gou)與路(lu)(lu)堤交界處的(de)“錯臺(tai)”現(xian)象(xiang)，提高行(xing)車安(an)全性。波(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)涵的(de)工后營運、養護成本低，工程實際造價(jia)也(ye)低于同類跨徑(jing)的(de)橋(qiao)梁、涵洞(dong)(dong)。鋼波(bo)(bo)(bo)(bo)紋(wen)涵管(guan)(guan)(guan)(guan)(guan)進出口也(ye)可按照邊坡比(bi)例做成斜口，加工波(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)徑(jing)范圍0．5～8 m，管(guan)(guan)(guan)(guan)(guan)壁厚度(du)為(wei)3 mm～7 mm，能夠滿足(zu)填土0．5 ～40 m厚的(de)需要。
