其間鋼質(zhi)波(bo)(bo)(bo)紋板(ban)(ban)材選用國(guo)內普遍運用的(de)A3或Q235-B熱軋鋼板(ban)(ban)，鋼板(ban)(ban)的(de)理化目標要求(qiu)到達GB700的(de)有關要求(qiu)，質(zhi)量輕。以內徑1m的(de)涵管為(wei)(wei)(wei)例，鋼波(bo)(bo)(bo)紋涵管每米質(zhi)量為(wei)(wei)(wei)60~300kg(依(yi)波(bo)(bo)(bo)紋方(fang)式和鋼板(ban)(ban)厚度而定)，僅為(wei)(wei)(wei)鋼筋(jin)砼圓管涵質(zhi)量的(de)百(bai)(bai)分之四(si)到百(bai)(bai)分之二十，這給施工運送和裝置帶來很大方(fang)便。
從資料與(yu)結構和(he)功能的本(ben)質關系上剖(pou)析(xi)，選(xuan)用(yong)柔性、高強度(du)的鋼(gang)波紋(wen)涵(han)管(guan)(guan)洞，不只具(ju)有(you)習慣地基(ji)與(yu)根底變形的能力。板(ban)(ban)(ban)的尺度(du)和(he)厚(hou)度(du)為便于板(ban)(ban)(ban)的加工(gong)制(zhi)造(zao)，結構的裝(zhuang)置(zhi)連接，進步板(ban)(ban)(ban)的制(zhi)造(zao)精(jing)度(du)，板(ban)(ban)(ban)材的尺度(du)宜(yi)習慣不同管(guan)(guan)徑的需(xu)要，以(yi)構成系列(lie)化。板(ban)(ban)(ban)的厚(hou)度(du)隨(sui)結構跨徑的大小改變，板(ban)(ban)(ban)厚(hou)可選(xuan)用(yong)2.5-8mm。
Based on the analysis of the essential relationship between data and structure and function, the selection of flexible and high-strength steel corrugated culvert tunnel not only has the ability to get used to the deformation of foundation and foundation. Size and thickness of plate in order to facilitate the processing and manufacturing of plate, the device connection of structure and improve the manufacturing accuracy of plate, the size of plate should be used to the needs of different pipe diameters to form serialization. The thickness of the plate changes with the size of the structural span, and the plate thickness can be 2.5-8mm.

良(liang)好的(de)焊接性能，滿意(yi)波(bo)(bo)(bo)紋管(guan)(guan)在制造進程(cheng)中的(de)焊接作業要求。管(guan)(guan)頂波(bo)(bo)(bo)峰(feng)與波(bo)(bo)(bo)谷(gu)(gu)處(chu)切向與軸向應(ying)力(li)應(ying)變隨(sui)(sui)波(bo)(bo)(bo)構成(cheng)拉壓替換的(de)改變規則。波(bo)(bo)(bo)峰(feng)和波(bo)(bo)(bo)谷(gu)(gu)在管(guan)(guan)頂、管(guan)(guan)底、管(guan)(guan)側(ce)均為應(ying)力(li)集中處(chu)，各管(guan)(guan)徑(jing)等(deng)效(xiao)應(ying)力(li)的(de)方位與荷載密切相關(guan)；大(da)等(deng)效(xiao)應(ying)力(li)總(zong)體(ti)上隨(sui)(sui)管(guan)(guan)徑(jing)的(de)添加(jia)而(er)添加(jia)；隨(sui)(sui)著波(bo)(bo)(bo)紋管(guan)(guan)涵(han)洞(dong)的(de)壁厚添加(jia)，大(da)等(deng)效(xiao)應(ying)力(li)呈對數(shu)減小(xiao)。
如果涵洞規劃得太小和太接近于地表特別是在露出的當地，并且水流速度緩慢，則在北部地區的冬季簡單凍住，還要阻塞。這能夠得到彌補，方法所以添加涵洞的坡度，選用無底的木制涵洞或在冰冷時節接近時，把涵洞進口端用軟樹技鋪蓋。//hanihanbj.com/
