鋼(gang)波(bo)紋涵管也(ye)叫波(bo)(bo)紋(wen)(wen)管(guan)涵(han)，是(shi)指(zhi)鋪埋在公路(lu)、鐵路(lu)路(lu)下(xia)的(de)(de)涵(han)洞用的(de)(de)螺紋(wen)(wen)波(bo)(bo)紋(wen)(wen)管(guan)，它是(shi)由(you)波(bo)(bo)形鋼板卷(juan)制(zhi)成(cheng)或用波(bo)(bo)形鋼片組拼成(cheng)的(de)(de)圓(yuan)形鋼結構(gou)管(guan)。金屬波(bo)(bo)紋(wen)(wen)管(guan)涵(han)的(de)(de)波(bo)(bo)紋(wen)(wen)結構(gou)可使(shi)涵(han)洞路(lu)面受(shou)力(li)合理，荷載分布均勻(yun)，并具有一定(ding)的(de)(de)抗變形能(neng)(neng)(neng)力(li)，能(neng)(neng)(neng)解(jie)決北(bei)方寒(han)冷地(di)(di)區（霜凍(dong)）對橋梁和(he)管(guan)涵(han)砼結構(gou)的(de)(de)破壞(huai)問題；使(shi)路(lu)表面沒有伸(shen)縮縫，提(ti)高行(xing)車舒適(shi)性；有利于(yu)(yu)改善軟土地(di)(di)基結構(gou)與路(lu)堤交界(jie)處的(de)(de)“錯(cuo)臺”現(xian)象，提(ti)高行(xing)車安全性。波(bo)(bo)紋(wen)(wen)管(guan)涵(han)的(de)(de)工(gong)(gong)后營運、養護成(cheng)本低(di)，工(gong)(gong)程(cheng)實際造價也(ye)低(di)于(yu)(yu)同類跨(kua)徑(jing)(jing)的(de)(de)橋梁、涵(han)洞。鋼波(bo)(bo)紋(wen)(wen)涵(han)管(guan)進出口也(ye)可按照邊坡比例做成(cheng)斜(xie)口，加工(gong)(gong)波(bo)(bo)紋(wen)(wen)管(guan)管(guan)徑(jing)(jing)范圍0．5～8 m，管(guan)壁厚度為3 mm～7 mm，能(neng)(neng)(neng)夠滿足填土0．5 ～40 m厚的(de)(de)需要(yao)。
