由鋼波紋涵管外圓(yuan)弧(hu)波紋膜片(pian)對壓力有線性特性，所以得到的外圓(yuan)弧(hu)波紋末膜片(pian)的計算結(jie)果，還能(neng)用(yong)于(yu)膜片(pian)受(shou)力變形較大的情況(kuang)。由此而(er)擬合出的設計公(gong)式能(neng)適(shi)應于(yu)變形較大的情況(kuang)。

鋼波紋涵管的外圓弧波紋末膜片的計算如何運行？

從(cong)儀表(biao)的(de)結構(gou)的(de)特(te)點來考慮，有些鋼(gang)波(bo)紋涵管(guan)(guan)的(de)無外波(bo)紋。鋼(gang)波(bo)紋涵管(guan)(guan)可(ke)分為有外波(bo)紋和無外波(bo)紋兩種(zhong)。對(dui)于(yu)不同(tong)的(de)鋼(gang)波(bo)紋涵管(guan)(guan)的(de)計算也(ye)是(shi)不一樣的(de)。

實踐證(zheng)實，用金(jin)屬波(bo)紋管(guan)涵(han)代(dai)替(ti)金(jin)屬筋混凝(ning)土進(jin)行(xing)涵(han)洞施(shi)(shi)(shi)工(gong)，不(bu)(bu)管(guan)從施(shi)(shi)(shi)工(gong)周期、施(shi)(shi)(shi)工(gong)造(zao)價、環保意義(yi)等(deng)方面(mian)都(dou)有其不(bu)(bu)可相(xiang)比的(de)優勝性(xing)，且用金(jin)屬波(bo)紋管(guan)涵(han)進(jin)行(xing)涵(han)洞施(shi)(shi)(shi)工(gong)，可大大進(jin)步(bu)道路行(xing)車的(de)恬靜度與安(an)全性(xing)，避免(mian)道路中(zhong)涵(han)洞的(de)“錯臺跳車”現形，有利于解決(jue)西北地區(qu)嚴寒霜凍對(dui)砼管(guan)涵(han)結構的(de)破壞題目(mu) 。

跟著鋼波紋涵管在(zai)世界(jie)各地(di)的(de)安(an)裝使用(yong)(yong)，證實了(le)此種(zhong)結構在(zai)各種(zhong)使用(yong)(yong)情(qing)況下的(de)通(tong)用(yong)(yong)性。在(zai)我國(guo)改革開放后，深圳及大(da)同(tong)煤(mei)礦開始從國(guo)外入口成品波(bo)紋(wen)管(guan)涵(han)進(jin)行(xing)涵(han)洞(dong)施工(gong)。之后，上海(hai)市公(gong)路(lu)治(zhi)理處、上海(hai)市政工(gong)程設(she)計研究院、上海(hai)同(tong)濟大(da)學對金屬(shu)波(bo)紋(wen)管(guan)涵(han)進(jin)行(xing)了(le)動、靜載試驗(yan)，結果表明能(neng)知(zhi)足設(she)計使用(yong)(yong)要求(qiu)，填補(bu)了(le)海(hai)內的(de)空缺，且迅速得(de)到(dao)推(tui)廣應用(yong)(yong)。幕(mu)墻一貫反應用(yong)(yong)于我國(guo)各地(di)公(gong)路(lu)舉措(cuo)措(cuo)施建設(she)當中。金屬(shu)波(bo)紋(wen)管(guan)涵(han)投入到(dao)了(le)青海(hai)公(gong)路(lu)施工(gong)當中，三(san)年的(de)實踐證實，金屬(shu)波(bo)紋(wen)管(guan)涵(han)在(zai)北(bei)方嚴寒地(di)區(qu)完全符合公(gong)路(lu)建設(she)當中的(de)涵(han)洞(dong)施工(gong)要求(qiu)。  

公(gong)路(lu)工(gong)(gong)(gong)程(cheng)的涵(han)洞(dong)一(yi)般采(cai)用金屬(shu)(shu)筋(jin)(jin)混(hun)凝(ning)土制作。現采(cai)用金屬(shu)(shu)波(bo)(bo)(bo)紋管涵(han)代替金屬(shu)(shu)筋(jin)(jin)混(hun)凝(ning)土進行涵(han)洞(dong)施(shi)(shi)工(gong)(gong)(gong)在(zai)海(hai)內時(shi)一(yi)項新技(ji)(ji)術，金屬(shu)(shu)波(bo)(bo)(bo)紋管涵(han)以其機能(neng)不亂、安(an)裝(zhuang)利(li)便、有利(li)環保、造(zao)價低等長(chang)處迅速(su)在(zai)公(gong)路(lu)施(shi)(shi)工(gong)(gong)(gong)中(zhong)(zhong)代替了金屬(shu)(shu)筋(jin)(jin)混(hun)凝(ning)土施(shi)(shi)工(gong)(gong)(gong)的涵(han)洞(dong)，發展遠(yuan)景非常廣闊。在(zai)公(gong)路(lu)施(shi)(shi)工(gong)(gong)(gong)中(zhong)(zhong)，應用金屬(shu)(shu)波(bo)(bo)(bo)紋管涵(han)代替金屬(shu)(shu)筋(jin)(jin)混(hun)凝(ning)土進行涵(han)洞(dong)施(shi)(shi)工(gong)(gong)(gong)的歷史已經有100多年了。1896年，美(mei)(mei)國率提高前輩行波(bo)(bo)(bo)紋管涵(han)通道、涵(han)管的可行性研究。其后，在(zai)美(mei)(mei)國、加拿大、澳大利(li)亞等國的公(gong)路(lu)建設(she)中(zhong)(zhong)，均采(cai)用了金屬(shu)(shu)波(bo)(bo)(bo)紋管涵(han)進行涵(han)洞(dong)的施(shi)(shi)工(gong)(gong)(gong)。1990年，日本高速(su)公(gong)路(lu)設(she)計，規(gui)范(fan)制定了波(bo)(bo)(bo)紋管涵(han)設(she)計技(ji)(ji)術規(gui)范(fan)。
