鋼波紋(wen)涵管也(ye)叫波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)涵(han)(han)，是(shi)指鋪埋在公(gong)路、鐵路路下的涵(han)(han)洞(dong)用的螺(luo)紋波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)，它是(shi)由(you)波(bo)(bo)(bo)(bo)形(xing)鋼(gang)板卷制成或(huo)用波(bo)(bo)(bo)(bo)形(xing)鋼(gang)片組拼成的圓形(xing)鋼(gang)結(jie)構(gou)管(guan)(guan)(guan)(guan)。金屬波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)涵(han)(han)的波(bo)(bo)(bo)(bo)紋結(jie)構(gou)可(ke)使(shi)涵(han)(han)洞(dong)路面受(shou)力合理，荷載分布均(jun)勻(yun)，并具有一定的抗變(bian)形(xing)能(neng)力，能(neng)解(jie)決(jue)北方寒冷地(di)區（霜(shuang)凍(dong)）對橋梁和管(guan)(guan)(guan)(guan)涵(han)(han)砼(tong)結(jie)構(gou)的破壞問題；使(shi)路表面沒有伸縮縫，提高行(xing)車舒適性；有利(li)于改善軟(ruan)土地(di)基結(jie)構(gou)與路堤(di)交(jiao)界處的“錯臺”現(xian)象，提高行(xing)車安全性。波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)涵(han)(han)的工(gong)后營運、養護成本(ben)低，工(gong)程實際造價也(ye)低于同類跨(kua)徑(jing)的橋梁、涵(han)(han)洞(dong)。鋼(gang)波(bo)(bo)(bo)(bo)紋涵(han)(han)管(guan)(guan)(guan)(guan)進出口也(ye)可(ke)按照邊坡比例做成斜口，加(jia)工(gong)波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)徑(jing)范圍0．5～8 m，管(guan)(guan)(guan)(guan)壁厚(hou)度為3 mm～7 mm，能(neng)夠滿(man)足填土0．5 ～40 m厚(hou)的需要。
