具(ju)有較大(da)的抗變形能力和(he)抗沉(chen)降能力，特(te)別適合于軟土(tu)、膨(peng)脹土(tu)、濕陷性黃土(tu)等地(di)(di)(di)基承載(zai)力較低的地(di)(di)(di)區和(he)地(di)(di)(di)震多發地(di)(di)(di)區。鋼質(zhi)波(bo)紋(wen)板通道(dao)現(xian)場拼裝，必須嚴(yan)格(ge)。按設計以及鋼質(zhi)波(bo)紋(wen)板通道(dao)施工(gong)安裝規(gui)范的要求施工(gong)。鋼波(bo)紋(wen)涵(han)管作為(wei)一(yi)種(zhong)新型(xing)技術在公路涵(han)洞工(gong)程施工(gong)中的具(ju)有很大(da)的優勢。

基礎的(de)地基承載力必須滿足沒(mei)計要求，嚴(yan)禁超(chao)挖(wa)回(hui)填虛土(tu)(tu)超(chao)過以及標高控制(zhi)。波(bo)紋鋼板安裝鋪設(she)應平順(shun)、穩固(gu)、管(guan)(guan)底(di)坡度不(bu)得出(chu)現反坡，管(guan)(guan)涵(han)內不(bu)得有(you)(you)泥土(tu)(tu)、磚石等(deng)雜物。鋼波(bo)紋涵(han)管(guan)(guan)是一種柔性結構，波(bo)紋管(guan)(guan)涵(han)在結構上(shang)具有(you)(you)橫(heng)向補償位移的(de)優良特(te)性，可以充分(fen)發(fa)揮(hui)鋼材(cai)抗拉性能(neng)強、抗變形能(neng)力優越的(de)特(te)點。

鋼(gang)波(bo)紋(wen)(wen)涵管(guan)(guan)(guan)的(de)(de)優點(dian)：鋼(gang)波(bo)紋(wen)(wen)涵管(guan)(guan)(guan)單體出廠(chang)時，必須(xu)附有產品質量(liang)合(he)格證書(shu)(shu)，沒有合(he)格證書(shu)(shu)的(de)(de)一(yi)律不(bu)能出廠(chang)。鋼(gang)波(bo)紋(wen)(wen)涵管(guan)(guan)(guan)從材料與結構(gou)和功能的(de)(de)本質關系上分(fen)析，采用柔性高強度的(de)(de)鋼(gang)波(bo)紋(wen)(wen)管(guan)(guan)(guan)涵洞由于軸(zhou)向(xiang)波(bo)紋(wen)(wen)的(de)(de)存在，使其(qi)具有優良的(de)(de)受(shou)力特征(zheng)，軸(zhou)向(xiang)和徑向(xiang)同時分(fen)布因荷載(zai)引起的(de)(de)應力應變，可以更大程度上分(fen)散荷載(zai)的(de)(de)應力集中(zhong)，更好地發(fa)揮(hui)鋼(gang)結構(gou)的(de)(de)優勢(shi)。

由于鋼波紋(wen)涵(han)(han)管(guan)施(shi)(shi)工簡(jian)單且施(shi)(shi)工工期短（一般一道(dao)涵(han)(han)洞的施(shi)(shi)工時間大約在10天-15天左右）縮短了多年(nian)凍土的裸露時間，凍融量小，故特別適用于多年(nian)凍土地區。鋼波紋(wen)涵(han)(han)管(guan)運到施(shi)(shi)工現場后(hou)，必須逐(zhu)塊檢查，凡在運輸過程中變形的鋼板不得使(shi)用。（hanihanbj.com）
