由鋼波紋涵管外(wai)圓(yuan)弧波紋(wen)膜片(pian)(pian)對(dui)壓力有線性特性，所以得到(dao)的外(wai)圓(yuan)弧波紋(wen)末膜片(pian)(pian)的計算結果，還能用(yong)于(yu)膜片(pian)(pian)受力變形(xing)較(jiao)大(da)的情況。由此而擬合出的設計公式(shi)能適應于(yu)變形(xing)較(jiao)大(da)的情況。

鋼波紋涵管的外圓弧波紋末膜片的計算如何運行？

從儀(yi)表的結構的特點來考慮，有(you)些鋼波紋(wen)涵管(guan)(guan)的無外波紋(wen)。鋼波紋(wen)涵管(guan)(guan)可(ke)分(fen)為有(you)外波紋(wen)和無外波紋(wen)兩種。對于(yu)不同的鋼波紋(wen)涵管(guan)(guan)的計算也是不一(yi)樣的。

實踐證實，用(yong)(yong)金屬波(bo)紋(wen)管(guan)(guan)涵(han)(han)代替金屬筋混凝(ning)土進行涵(han)(han)洞施(shi)(shi)工(gong)(gong)，不管(guan)(guan)從施(shi)(shi)工(gong)(gong)周期、施(shi)(shi)工(gong)(gong)造價(jia)、環保意義(yi)等(deng)方面都有其不可相比的優(you)勝性(xing)，且(qie)用(yong)(yong)金屬波(bo)紋(wen)管(guan)(guan)涵(han)(han)進行涵(han)(han)洞施(shi)(shi)工(gong)(gong)，可大大進步道路行車的恬靜(jing)度(du)與(yu)安全(quan)性(xing)，避(bi)免道路中(zhong)涵(han)(han)洞的“錯(cuo)臺(tai)跳車”現形(xing)，有利于解決西北地(di)區嚴寒霜凍(dong)對砼管(guan)(guan)涵(han)(han)結構(gou)的破(po)壞題目 。

跟著鋼波紋涵管在(zai)世界各(ge)地(di)(di)的(de)安(an)裝使(shi)(shi)用(yong)(yong)(yong)(yong)，證實了此種(zhong)結(jie)構在(zai)各(ge)種(zhong)使(shi)(shi)用(yong)(yong)(yong)(yong)情況(kuang)下的(de)通用(yong)(yong)(yong)(yong)性。在(zai)我國(guo)改革開放(fang)后，深圳及大同煤礦開始從國(guo)外入口成品波(bo)紋管(guan)涵(han)(han)進(jin)行涵(han)(han)洞施工(gong)。之(zhi)后，上(shang)海(hai)市公(gong)路治理處、上(shang)海(hai)市政工(gong)程設計(ji)研究院、上(shang)海(hai)同濟大學對金(jin)屬波(bo)紋管(guan)涵(han)(han)進(jin)行了動、靜載試驗，結(jie)果(guo)表明能知(zhi)足設計(ji)使(shi)(shi)用(yong)(yong)(yong)(yong)要求，填補了海(hai)內(nei)的(de)空(kong)缺，且(qie)迅速得到(dao)推(tui)廣應(ying)用(yong)(yong)(yong)(yong)。幕墻(qiang)一貫反(fan)應(ying)用(yong)(yong)(yong)(yong)于我國(guo)各(ge)地(di)(di)公(gong)路舉措(cuo)(cuo)措(cuo)(cuo)施建設當(dang)中(zhong)。金(jin)屬波(bo)紋管(guan)涵(han)(han)投入到(dao)了青海(hai)公(gong)路施工(gong)當(dang)中(zhong)，三年的(de)實踐證實，金(jin)屬波(bo)紋管(guan)涵(han)(han)在(zai)北方嚴寒地(di)(di)區完全符合(he)公(gong)路建設當(dang)中(zhong)的(de)涵(han)(han)洞施工(gong)要求。  

公路(lu)工程的涵(han)洞(dong)一(yi)般(ban)采用(yong)金屬(shu)(shu)(shu)(shu)筋混(hun)凝(ning)土(tu)(tu)制(zhi)作。現采用(yong)金屬(shu)(shu)(shu)(shu)波(bo)(bo)紋管涵(han)代(dai)替金屬(shu)(shu)(shu)(shu)筋混(hun)凝(ning)土(tu)(tu)進(jin)行涵(han)洞(dong)施工在(zai)海內(nei)時一(yi)項(xiang)新技術，金屬(shu)(shu)(shu)(shu)波(bo)(bo)紋管涵(han)以其機能不亂、安裝利便、有利環保、造(zao)價低等長處(chu)迅速在(zai)公路(lu)施工中代(dai)替了(le)金屬(shu)(shu)(shu)(shu)筋混(hun)凝(ning)土(tu)(tu)施工的涵(han)洞(dong)，發(fa)展遠景非(fei)常廣闊(kuo)。在(zai)公路(lu)施工中，應用(yong)金屬(shu)(shu)(shu)(shu)波(bo)(bo)紋管涵(han)代(dai)替金屬(shu)(shu)(shu)(shu)筋混(hun)凝(ning)土(tu)(tu)進(jin)行涵(han)洞(dong)施工的歷史已(yi)經有100多(duo)年了(le)。1896年，美國率(lv)提高前輩行波(bo)(bo)紋管涵(han)通道、涵(han)管的可(ke)行性研究。其后(hou)，在(zai)美國、加(jia)拿大、澳大利亞等國的公路(lu)建設(she)中，均采用(yong)了(le)金屬(shu)(shu)(shu)(shu)波(bo)(bo)紋管涵(han)進(jin)行涵(han)洞(dong)的施工。1990年，日(ri)本高速公路(lu)設(she)計，規(gui)范(fan)制(zhi)定了(le)波(bo)(bo)紋管涵(han)設(she)計技術規(gui)范(fan)。
