由鋼波紋涵管外(wai)(wai)圓(yuan)弧(hu)波紋膜片對壓(ya)力(li)(li)有線(xian)性特性，所以得到的(de)(de)外(wai)(wai)圓(yuan)弧(hu)波紋末膜片的(de)(de)計(ji)算結果，還能用(yong)于(yu)膜片受(shou)力(li)(li)變(bian)形較(jiao)大(da)的(de)(de)情況。由(you)此而擬合出的(de)(de)設計(ji)公(gong)式能適應于(yu)變(bian)形較(jiao)大(da)的(de)(de)情況。

鋼波紋涵管的外圓弧波紋末膜片的計算如何運行？

從(cong)儀表的結構的特點來考(kao)慮，有(you)些鋼波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵管(guan)的無外波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)。鋼波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵管(guan)可分為(wei)有(you)外波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)和無外波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)兩種。對于(yu)不同的鋼波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵管(guan)的計算也是不一樣的。

實踐證(zheng)實，用(yong)金(jin)屬波(bo)紋管(guan)涵(han)代(dai)替金(jin)屬筋混(hun)凝(ning)土進(jin)行(xing)涵(han)洞(dong)施(shi)工(gong)，不管(guan)從施(shi)工(gong)周期、施(shi)工(gong)造價(jia)、環保(bao)意義等方面都有其(qi)不可(ke)相比的(de)(de)優勝性，且用(yong)金(jin)屬波(bo)紋管(guan)涵(han)進(jin)行(xing)涵(han)洞(dong)施(shi)工(gong)，可(ke)大(da)大(da)進(jin)步道(dao)路(lu)行(xing)車的(de)(de)恬靜度與安全性，避(bi)免道(dao)路(lu)中涵(han)洞(dong)的(de)(de)“錯臺跳車”現形，有利于解決西(xi)北地區嚴(yan)寒霜凍(dong)對砼(tong)管(guan)涵(han)結構的(de)(de)破(po)壞題目 。

跟著鋼波紋涵管在(zai)(zai)世界各地(di)的安(an)裝使用(yong)(yong)(yong)(yong)，證實了此種結構(gou)在(zai)(zai)各種使用(yong)(yong)(yong)(yong)情(qing)況下的通(tong)用(yong)(yong)(yong)(yong)性。在(zai)(zai)我(wo)國(guo)改(gai)革開放(fang)后，深圳及大同(tong)煤礦(kuang)開始從國(guo)外(wai)入(ru)口成品波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)進行涵(han)(han)洞(dong)施(shi)工。之后，上海市公路(lu)治理處、上海市政工程設計研究(jiu)院、上海同(tong)濟大學對金屬(shu)(shu)波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)進行了動、靜載(zai)試驗，結果表明能知足設計使用(yong)(yong)(yong)(yong)要求，填補了海內的空缺，且迅速得(de)到推廣應用(yong)(yong)(yong)(yong)。幕墻(qiang)一貫反應用(yong)(yong)(yong)(yong)于我(wo)國(guo)各地(di)公路(lu)舉措措施(shi)建(jian)設當中。金屬(shu)(shu)波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)投入(ru)到了青海公路(lu)施(shi)工當中，三年的實踐證實，金屬(shu)(shu)波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)在(zai)(zai)北方嚴寒地(di)區完全(quan)符合公路(lu)建(jian)設當中的涵(han)(han)洞(dong)施(shi)工要求。  

公(gong)路工(gong)(gong)程的涵(han)(han)洞(dong)(dong)一般采用(yong)金(jin)(jin)(jin)(jin)屬(shu)(shu)筋混(hun)凝(ning)(ning)土(tu)(tu)制作(zuo)。現采用(yong)金(jin)(jin)(jin)(jin)屬(shu)(shu)波(bo)(bo)紋(wen)管涵(han)(han)代替(ti)金(jin)(jin)(jin)(jin)屬(shu)(shu)筋混(hun)凝(ning)(ning)土(tu)(tu)進(jin)行(xing)涵(han)(han)洞(dong)(dong)施工(gong)(gong)在(zai)(zai)海內時一項新技(ji)術，金(jin)(jin)(jin)(jin)屬(shu)(shu)波(bo)(bo)紋(wen)管涵(han)(han)以(yi)其機能(neng)不亂(luan)、安(an)裝利(li)便、有(you)利(li)環保、造價低等長(chang)處迅速(su)在(zai)(zai)公(gong)路施工(gong)(gong)中代替(ti)了金(jin)(jin)(jin)(jin)屬(shu)(shu)筋混(hun)凝(ning)(ning)土(tu)(tu)施工(gong)(gong)的涵(han)(han)洞(dong)(dong)，發展遠景非(fei)常廣闊(kuo)。在(zai)(zai)公(gong)路施工(gong)(gong)中，應用(yong)金(jin)(jin)(jin)(jin)屬(shu)(shu)波(bo)(bo)紋(wen)管涵(han)(han)代替(ti)金(jin)(jin)(jin)(jin)屬(shu)(shu)筋混(hun)凝(ning)(ning)土(tu)(tu)進(jin)行(xing)涵(han)(han)洞(dong)(dong)施工(gong)(gong)的歷史(shi)已經有(you)100多(duo)年(nian)了。1896年(nian)，美國率提高前(qian)輩(bei)行(xing)波(bo)(bo)紋(wen)管涵(han)(han)通道、涵(han)(han)管的可行(xing)性研究。其后，在(zai)(zai)美國、加(jia)拿大、澳大利(li)亞等國的公(gong)路建設中，均采用(yong)了金(jin)(jin)(jin)(jin)屬(shu)(shu)波(bo)(bo)紋(wen)管涵(han)(han)進(jin)行(xing)涵(han)(han)洞(dong)(dong)的施工(gong)(gong)。1990年(nian)，日本高速(su)公(gong)路設計(ji)，規范(fan)制定了波(bo)(bo)紋(wen)管涵(han)(han)設計(ji)技(ji)術規范(fan)。
