鋼波紋涵管也叫波(bo)(bo)紋(wen)(wen)(wen)管(guan)涵，是指鋪埋在公路(lu)、鐵路(lu)路(lu)下的涵洞用的螺紋(wen)(wen)(wen)波(bo)(bo)紋(wen)(wen)(wen)管(guan)，它(ta)是由波(bo)(bo)形鋼板(ban)卷(juan)制成(cheng)(cheng)或用波(bo)(bo)形鋼片組拼(pin)成(cheng)(cheng)的圓形鋼結(jie)構管(guan)。金屬波(bo)(bo)紋(wen)(wen)(wen)管(guan)涵的波(bo)(bo)紋(wen)(wen)(wen)結(jie)構可使涵洞路(lu)面(mian)受力合理，荷載(zai)分(fen)布均勻，并具有一(yi)定(ding)的抗變(bian)形能力，能解決北方寒冷地區（霜(shuang)凍(dong)）對橋梁和管(guan)涵砼(tong)結(jie)構的破壞問題；使路(lu)表面(mian)沒有伸縮縫，提(ti)高行(xing)車舒適性；有利于改善(shan)軟土(tu)地基結(jie)構與(yu)路(lu)堤交(jiao)界處(chu)的“錯臺(tai)”現象，提(ti)高行(xing)車安全性。波(bo)(bo)紋(wen)(wen)(wen)管(guan)涵的工(gong)后(hou)營運、養(yang)護成(cheng)(cheng)本(ben)低(di)，工(gong)程實際造價也低(di)于同類跨徑的橋梁、涵洞。鋼波(bo)(bo)紋(wen)(wen)(wen)涵管(guan)進出口也可按照邊坡(po)比例做(zuo)成(cheng)(cheng)斜口，加工(gong)波(bo)(bo)紋(wen)(wen)(wen)管(guan)管(guan)徑范圍0．5～8 m，管(guan)壁厚度為3 mm～7 mm，能夠滿(man)足填土(tu)0．5 ～40 m厚的需要。
