鋼波紋涵管也叫波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)，是指鋪埋(mai)在公路(lu)(lu)、鐵路(lu)(lu)路(lu)(lu)下的(de)(de)涵(han)(han)(han)洞(dong)(dong)用(yong)的(de)(de)螺紋(wen)(wen)波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)，它是由波(bo)(bo)形(xing)鋼(gang)(gang)板(ban)卷(juan)制成(cheng)(cheng)或用(yong)波(bo)(bo)形(xing)鋼(gang)(gang)片(pian)組拼成(cheng)(cheng)的(de)(de)圓形(xing)鋼(gang)(gang)結構管(guan)(guan)(guan)。金屬波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)的(de)(de)波(bo)(bo)紋(wen)(wen)結構可(ke)使涵(han)(han)(han)洞(dong)(dong)路(lu)(lu)面受(shou)力合理，荷載分布均勻，并具有一(yi)定(ding)的(de)(de)抗變形(xing)能力，能解決北方寒冷(leng)地(di)區（霜(shuang)凍）對橋(qiao)梁和管(guan)(guan)(guan)涵(han)(han)(han)砼結構的(de)(de)破壞問題；使路(lu)(lu)表面沒有伸縮縫，提(ti)(ti)高(gao)行(xing)車舒適性；有利于改善軟土地(di)基(ji)結構與(yu)路(lu)(lu)堤(di)交界處的(de)(de)“錯臺”現象，提(ti)(ti)高(gao)行(xing)車安全(quan)性。波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)的(de)(de)工后營運、養護成(cheng)(cheng)本低(di)，工程實際造價也低(di)于同(tong)類跨徑(jing)的(de)(de)橋(qiao)梁、涵(han)(han)(han)洞(dong)(dong)。鋼(gang)(gang)波(bo)(bo)紋(wen)(wen)涵(han)(han)(han)管(guan)(guan)(guan)進出口也可(ke)按照邊坡比例做成(cheng)(cheng)斜口，加工波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)徑(jing)范圍0．5～8 m，管(guan)(guan)(guan)壁厚度(du)為3 mm～7 mm，能夠滿足(zu)填土0．5 ～40 m厚的(de)(de)需要。
