鋼波紋涵管也叫波(bo)紋(wen)管(guan)(guan)(guan)(guan)涵(han)(han)(han)，是指鋪(pu)埋在公路(lu)、鐵路(lu)路(lu)下(xia)的(de)涵(han)(han)(han)洞用(yong)的(de)螺紋(wen)波(bo)紋(wen)管(guan)(guan)(guan)(guan)，它是由波(bo)形鋼板卷制成或用(yong)波(bo)形鋼片組拼成的(de)圓形鋼結(jie)構(gou)(gou)管(guan)(guan)(guan)(guan)。金屬(shu)波(bo)紋(wen)管(guan)(guan)(guan)(guan)涵(han)(han)(han)的(de)波(bo)紋(wen)結(jie)構(gou)(gou)可使(shi)涵(han)(han)(han)洞路(lu)面受力合理(li)，荷載分(fen)布均勻，并具有(you)一定的(de)抗變形能(neng)(neng)力，能(neng)(neng)解決北方寒冷地區（霜凍）對橋梁和管(guan)(guan)(guan)(guan)涵(han)(han)(han)砼結(jie)構(gou)(gou)的(de)破(po)壞問(wen)題；使(shi)路(lu)表面沒有(you)伸(shen)縮縫，提高行(xing)車舒適性(xing)；有(you)利于(yu)改善軟土(tu)地基結(jie)構(gou)(gou)與路(lu)堤交界(jie)處的(de)“錯(cuo)臺”現(xian)象，提高行(xing)車安全性(xing)。波(bo)紋(wen)管(guan)(guan)(guan)(guan)涵(han)(han)(han)的(de)工(gong)(gong)后(hou)營運、養護成本低(di)，工(gong)(gong)程實際造價也低(di)于(yu)同類跨徑(jing)的(de)橋梁、涵(han)(han)(han)洞。鋼波(bo)紋(wen)涵(han)(han)(han)管(guan)(guan)(guan)(guan)進出口(kou)也可按照邊坡比例做(zuo)成斜(xie)口(kou)，加(jia)工(gong)(gong)波(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)徑(jing)范圍0．5～8 m，管(guan)(guan)(guan)(guan)壁厚度為3 mm～7 mm，能(neng)(neng)夠滿足填土(tu)0．5 ～40 m厚的(de)需要(yao)。
