由鋼波紋涵管外(wai)圓弧波(bo)紋(wen)膜片對壓力有線性特性，所以得到的外(wai)圓弧波(bo)紋(wen)末(mo)膜片的計算結果，還能用于(yu)膜片受力變(bian)形較(jiao)大(da)的情(qing)況。由(you)此而擬合(he)出的設計公式能適應于(yu)變(bian)形較(jiao)大(da)的情(qing)況。

鋼波紋涵管的外圓弧波紋末膜片的計算如何運行？

從(cong)儀(yi)表的結構的特點(dian)來考(kao)慮，有些(xie)鋼波(bo)紋(wen)涵(han)管(guan)的無外(wai)波(bo)紋(wen)。鋼波(bo)紋(wen)涵(han)管(guan)可分為有外(wai)波(bo)紋(wen)和(he)無外(wai)波(bo)紋(wen)兩種。對于(yu)不同(tong)的鋼波(bo)紋(wen)涵(han)管(guan)的計算也(ye)是不一樣的。

實踐證實，用(yong)金(jin)屬(shu)波紋(wen)管(guan)涵(han)(han)代替金(jin)屬(shu)筋(jin)混凝土(tu)進(jin)行(xing)涵(han)(han)洞施(shi)工(gong)(gong)(gong)，不(bu)管(guan)從(cong)施(shi)工(gong)(gong)(gong)周期、施(shi)工(gong)(gong)(gong)造(zao)價、環保意義等方(fang)面都(dou)有(you)其不(bu)可相(xiang)比的優勝性，且用(yong)金(jin)屬(shu)波紋(wen)管(guan)涵(han)(han)進(jin)行(xing)涵(han)(han)洞施(shi)工(gong)(gong)(gong)，可大(da)大(da)進(jin)步道(dao)路行(xing)車的恬靜度與(yu)安全性，避免(mian)道(dao)路中涵(han)(han)洞的“錯臺跳(tiao)車”現形(xing)，有(you)利于解(jie)決西(xi)北地區(qu)嚴寒霜(shuang)凍對砼管(guan)涵(han)(han)結構的破(po)壞(huai)題目 。

跟著鋼波紋涵管在世界各(ge)地的安裝(zhuang)使用(yong)(yong)，證(zheng)實(shi)了此種結(jie)構在各(ge)種使用(yong)(yong)情況下的通用(yong)(yong)性。在我(wo)國(guo)改革開放后，深圳(zhen)及(ji)大同(tong)煤礦開始從國(guo)外入(ru)(ru)口成品波(bo)紋(wen)(wen)管(guan)涵進行涵洞(dong)施(shi)工。之后，上海市公路治理(li)處、上海市政(zheng)工程設(she)計研究院、上海同(tong)濟大學對金屬波(bo)紋(wen)(wen)管(guan)涵進行了動(dong)、靜載試驗(yan)，結(jie)果表(biao)明能(neng)知足設(she)計使用(yong)(yong)要求，填(tian)補了海內的空(kong)缺(que)，且迅(xun)速得(de)到推廣應用(yong)(yong)。幕墻一貫反應用(yong)(yong)于我(wo)國(guo)各(ge)地公路舉措措施(shi)建(jian)設(she)當(dang)中。金屬波(bo)紋(wen)(wen)管(guan)涵投入(ru)(ru)到了青海公路施(shi)工當(dang)中，三年(nian)的實(shi)踐證(zheng)實(shi)，金屬波(bo)紋(wen)(wen)管(guan)涵在北方嚴寒地區完(wan)全符合公路建(jian)設(she)當(dang)中的涵洞(dong)施(shi)工要求。  

公(gong)(gong)(gong)路(lu)工(gong)(gong)(gong)程的(de)(de)(de)涵(han)(han)洞(dong)一(yi)般采用(yong)金(jin)屬(shu)筋混(hun)(hun)凝土(tu)制作。現采用(yong)金(jin)屬(shu)波紋(wen)管(guan)涵(han)(han)代(dai)替(ti)金(jin)屬(shu)筋混(hun)(hun)凝土(tu)進(jin)行涵(han)(han)洞(dong)施工(gong)(gong)(gong)在海內時一(yi)項新技術，金(jin)屬(shu)波紋(wen)管(guan)涵(han)(han)以其(qi)機(ji)能不亂、安(an)裝利便、有利環保、造價低等長處迅速在公(gong)(gong)(gong)路(lu)施工(gong)(gong)(gong)中(zhong)(zhong)代(dai)替(ti)了金(jin)屬(shu)筋混(hun)(hun)凝土(tu)施工(gong)(gong)(gong)的(de)(de)(de)涵(han)(han)洞(dong)，發展遠景(jing)非(fei)常廣闊(kuo)。在公(gong)(gong)(gong)路(lu)施工(gong)(gong)(gong)中(zhong)(zhong)，應用(yong)金(jin)屬(shu)波紋(wen)管(guan)涵(han)(han)代(dai)替(ti)金(jin)屬(shu)筋混(hun)(hun)凝土(tu)進(jin)行涵(han)(han)洞(dong)施工(gong)(gong)(gong)的(de)(de)(de)歷史已經(jing)有100多(duo)年(nian)了。1896年(nian)，美國(guo)(guo)率提高前輩行波紋(wen)管(guan)涵(han)(han)通道、涵(han)(han)管(guan)的(de)(de)(de)可行性研究(jiu)。其(qi)后，在美國(guo)(guo)、加拿大(da)、澳大(da)利亞等國(guo)(guo)的(de)(de)(de)公(gong)(gong)(gong)路(lu)建設(she)中(zhong)(zhong)，均(jun)采用(yong)了金(jin)屬(shu)波紋(wen)管(guan)涵(han)(han)進(jin)行涵(han)(han)洞(dong)的(de)(de)(de)施工(gong)(gong)(gong)。1990年(nian)，日(ri)本高速公(gong)(gong)(gong)路(lu)設(she)計，規范(fan)制定了波紋(wen)管(guan)涵(han)(han)設(she)計技術規范(fan)。
