鋼波紋涵管也(ye)叫波紋管(guan)(guan)(guan)(guan)涵(han)，是指鋪埋(mai)在公路、鐵路路下的(de)涵(han)洞用的(de)螺紋波紋管(guan)(guan)(guan)(guan)，它是由波形(xing)(xing)鋼(gang)(gang)板卷制成(cheng)或用波形(xing)(xing)鋼(gang)(gang)片(pian)組拼成(cheng)的(de)圓形(xing)(xing)鋼(gang)(gang)結構(gou)(gou)管(guan)(guan)(guan)(guan)。金(jin)屬波紋管(guan)(guan)(guan)(guan)涵(han)的(de)波紋結構(gou)(gou)可(ke)使涵(han)洞路面受力合理，荷載分布(bu)均勻，并(bing)具有(you)一(yi)定(ding)的(de)抗變形(xing)(xing)能(neng)(neng)力，能(neng)(neng)解決北方寒冷地區（霜凍(dong)）對橋梁和管(guan)(guan)(guan)(guan)涵(han)砼(tong)結構(gou)(gou)的(de)破壞問題；使路表面沒(mei)有(you)伸(shen)縮縫，提高(gao)行車舒適(shi)性(xing)；有(you)利于(yu)改善軟土地基結構(gou)(gou)與路堤交界處(chu)的(de)“錯臺”現(xian)象，提高(gao)行車安全性(xing)。波紋管(guan)(guan)(guan)(guan)涵(han)的(de)工(gong)后營運、養護成(cheng)本(ben)低，工(gong)程(cheng)實際造價也(ye)低于(yu)同類跨徑(jing)的(de)橋梁、涵(han)洞。鋼(gang)(gang)波紋涵(han)管(guan)(guan)(guan)(guan)進出口也(ye)可(ke)按照邊坡比例做成(cheng)斜口，加工(gong)波紋管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)徑(jing)范(fan)圍(wei)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0．5 ～40 m厚的(de)需(xu)要(yao)。
