鋼波(bo)紋涵管(guan)也叫波(bo)(bo)(bo)(bo)(bo)紋(wen)管(guan)涵(han)(han)，是指(zhi)鋪埋在公路、鐵路路下的涵(han)(han)洞(dong)用(yong)的螺紋(wen)波(bo)(bo)(bo)(bo)(bo)紋(wen)管(guan)，它(ta)是由波(bo)(bo)(bo)(bo)(bo)形(xing)鋼(gang)板(ban)卷(juan)制成或(huo)用(yong)波(bo)(bo)(bo)(bo)(bo)形(xing)鋼(gang)片組拼(pin)成的圓形(xing)鋼(gang)結(jie)構(gou)(gou)管(guan)。金屬(shu)波(bo)(bo)(bo)(bo)(bo)紋(wen)管(guan)涵(han)(han)的波(bo)(bo)(bo)(bo)(bo)紋(wen)結(jie)構(gou)(gou)可(ke)(ke)使(shi)涵(han)(han)洞(dong)路面受力(li)合(he)理(li)，荷載分布均勻，并具有(you)(you)一定的抗(kang)變形(xing)能(neng)力(li)，能(neng)解決(jue)北方寒冷(leng)地區（霜凍(dong)）對橋(qiao)梁(liang)和管(guan)涵(han)(han)砼(tong)結(jie)構(gou)(gou)的破(po)壞(huai)問題；使(shi)路表(biao)面沒有(you)(you)伸縮縫，提高行車(che)舒(shu)適性；有(you)(you)利(li)于(yu)改善軟土地基(ji)結(jie)構(gou)(gou)與路堤(di)交界(jie)處的“錯臺”現象，提高行車(che)安全性。波(bo)(bo)(bo)(bo)(bo)紋(wen)管(guan)涵(han)(han)的工后(hou)營運、養護(hu)成本低，工程(cheng)實際(ji)造價(jia)也低于(yu)同類跨徑的橋(qiao)梁(liang)、涵(han)(han)洞(dong)。鋼(gang)波(bo)(bo)(bo)(bo)(bo)紋(wen)涵(han)(han)管(guan)進出口也可(ke)(ke)按照邊坡(po)比例(li)做(zuo)成斜口，加工波(bo)(bo)(bo)(bo)(bo)紋(wen)管(guan)管(guan)徑范(fan)圍0．5～8 m，管(guan)壁厚(hou)(hou)度為3 mm～7 mm，能(neng)夠滿足填土0．5 ～40 m厚(hou)(hou)的需要。
