鋼波紋涵管也叫波(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)(han)，是指(zhi)鋪(pu)埋(mai)在公路、鐵(tie)路路下的涵(han)(han)(han)洞(dong)用的螺紋(wen)波(bo)(bo)紋(wen)管(guan)(guan)，它是由波(bo)(bo)形(xing)鋼(gang)板(ban)卷制成或用波(bo)(bo)形(xing)鋼(gang)片組拼成的圓形(xing)鋼(gang)結(jie)(jie)構(gou)管(guan)(guan)。金屬波(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)(han)的波(bo)(bo)紋(wen)結(jie)(jie)構(gou)可使涵(han)(han)(han)洞(dong)路面(mian)受(shou)力(li)合理，荷載分布(bu)均勻，并具有(you)一定(ding)的抗變(bian)形(xing)能(neng)力(li)，能(neng)解決北方寒(han)冷地(di)區（霜凍）對(dui)橋(qiao)梁(liang)和(he)管(guan)(guan)涵(han)(han)(han)砼結(jie)(jie)構(gou)的破壞問題；使路表面(mian)沒有(you)伸縮縫，提(ti)高行車舒適性；有(you)利于(yu)改(gai)善軟土地(di)基結(jie)(jie)構(gou)與路堤交界處的“錯臺(tai)”現象，提(ti)高行車安全性。波(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)(han)的工(gong)后營運(yun)、養護成本(ben)低(di)，工(gong)程實(shi)際造(zao)價也低(di)于(yu)同類跨徑(jing)的橋(qiao)梁(liang)、涵(han)(han)(han)洞(dong)。鋼(gang)波(bo)(bo)紋(wen)涵(han)(han)(han)管(guan)(guan)進出(chu)口也可按(an)照邊坡比例做成斜(xie)口，加工(gong)波(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)徑(jing)范圍0．5～8 m，管(guan)(guan)壁厚(hou)度為(wei)3 mm～7 mm，能(neng)夠滿足填土0．5 ～40 m厚(hou)的需要。
