鋼波(bo)紋涵管也叫波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵，是指鋪埋在公路(lu)、鐵路(lu)路(lu)下的(de)涵洞用的(de)螺(luo)紋(wen)(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)，它是由波(bo)(bo)(bo)形(xing)(xing)鋼(gang)(gang)板(ban)卷制成或用波(bo)(bo)(bo)形(xing)(xing)鋼(gang)(gang)片組拼成的(de)圓(yuan)形(xing)(xing)鋼(gang)(gang)結(jie)構(gou)(gou)管(guan)(guan)(guan)。金屬(shu)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵的(de)波(bo)(bo)(bo)紋(wen)(wen)(wen)結(jie)構(gou)(gou)可使涵洞路(lu)面(mian)受力(li)合理，荷載分布均(jun)勻，并具(ju)有(you)(you)一定的(de)抗變形(xing)(xing)能力(li)，能解決(jue)北(bei)方寒冷地(di)區（霜凍(dong)）對橋(qiao)梁(liang)和(he)管(guan)(guan)(guan)涵砼結(jie)構(gou)(gou)的(de)破壞問(wen)題；使路(lu)表面(mian)沒(mei)有(you)(you)伸縮縫(feng)，提(ti)高行(xing)車舒適性；有(you)(you)利于改善軟(ruan)土地(di)基(ji)結(jie)構(gou)(gou)與路(lu)堤交界處的(de)“錯(cuo)臺”現象，提(ti)高行(xing)車安全性。波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵的(de)工后營運(yun)、養護成本(ben)低(di)，工程實際造價也低(di)于同類跨徑的(de)橋(qiao)梁(liang)、涵洞。鋼(gang)(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)涵管(guan)(guan)(guan)進出口也可按照邊(bian)坡比例(li)做成斜口，加工波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)徑范圍0．5～8 m，管(guan)(guan)(guan)壁厚度為3 mm～7 mm，能夠滿足填土0．5 ～40 m厚的(de)需要。
