由鋼波紋涵管外(wai)圓弧波紋膜片(pian)對壓力有線性(xing)特性(xing)，所以得(de)到的(de)外(wai)圓弧波紋末(mo)膜片(pian)的(de)計算結果，還能用于(yu)膜片(pian)受(shou)力變形較大的(de)情(qing)況。由此而擬合出的(de)設計公式能適應于(yu)變形較大的(de)情(qing)況。

鋼波紋涵管的外圓弧波紋末膜片的計算如何運行？

從儀表的(de)結構的(de)特點來考慮，有些鋼(gang)波(bo)(bo)(bo)(bo)紋涵(han)(han)管的(de)無外(wai)波(bo)(bo)(bo)(bo)紋。鋼(gang)波(bo)(bo)(bo)(bo)紋涵(han)(han)管可分為有外(wai)波(bo)(bo)(bo)(bo)紋和無外(wai)波(bo)(bo)(bo)(bo)紋兩(liang)種。對于(yu)不同的(de)鋼(gang)波(bo)(bo)(bo)(bo)紋涵(han)(han)管的(de)計算(suan)也是不一樣的(de)。

實(shi)踐證實(shi)，用金(jin)屬波(bo)紋管(guan)涵(han)(han)代替金(jin)屬筋混凝土(tu)進行(xing)涵(han)(han)洞施(shi)(shi)(shi)工(gong)，不管(guan)從施(shi)(shi)(shi)工(gong)周(zhou)期、施(shi)(shi)(shi)工(gong)造(zao)價、環保(bao)意(yi)義等方面都有其不可(ke)相比的優勝性，且(qie)用金(jin)屬波(bo)紋管(guan)涵(han)(han)進行(xing)涵(han)(han)洞施(shi)(shi)(shi)工(gong)，可(ke)大大進步(bu)道路(lu)行(xing)車的恬靜度(du)與安(an)全性，避免道路(lu)中涵(han)(han)洞的“錯(cuo)臺跳(tiao)車”現形，有利于(yu)解決西北地區嚴寒霜凍對砼管(guan)涵(han)(han)結構的破壞題目 。

跟著鋼波紋涵管在(zai)(zai)世界各(ge)地的安裝(zhuang)使用(yong)，證實了此種(zhong)結構在(zai)(zai)各(ge)種(zhong)使用(yong)情況(kuang)下的通(tong)用(yong)性。在(zai)(zai)我(wo)國(guo)(guo)改革開放后(hou)，深圳及大同(tong)(tong)煤(mei)礦開始(shi)從國(guo)(guo)外入口成品(pin)波紋(wen)管(guan)涵(han)進行(xing)涵(han)洞(dong)施(shi)工。之后(hou)，上(shang)海(hai)(hai)市公路(lu)治(zhi)理處、上(shang)海(hai)(hai)市政(zheng)工程設計研究院、上(shang)海(hai)(hai)同(tong)(tong)濟大學對金屬波紋(wen)管(guan)涵(han)進行(xing)了動、靜載(zai)試(shi)驗，結果表明(ming)能知足(zu)設計使用(yong)要求(qiu)，填補了海(hai)(hai)內的空缺，且(qie)迅速得到(dao)推(tui)廣應用(yong)。幕(mu)墻一貫反應用(yong)于(yu)我(wo)國(guo)(guo)各(ge)地公路(lu)舉措措施(shi)建設當中(zhong)。金屬波紋(wen)管(guan)涵(han)投入到(dao)了青海(hai)(hai)公路(lu)施(shi)工當中(zhong)，三(san)年(nian)的實踐(jian)證實，金屬波紋(wen)管(guan)涵(han)在(zai)(zai)北方嚴(yan)寒地區完(wan)全符(fu)合公路(lu)建設當中(zhong)的涵(han)洞(dong)施(shi)工要求(qiu)。  

公(gong)路工(gong)程(cheng)的涵(han)(han)(han)(han)(han)(han)洞一般采(cai)用金(jin)(jin)(jin)屬(shu)(shu)筋(jin)混(hun)凝(ning)(ning)土制作(zuo)。現(xian)采(cai)用金(jin)(jin)(jin)屬(shu)(shu)波(bo)紋管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)代替(ti)金(jin)(jin)(jin)屬(shu)(shu)筋(jin)混(hun)凝(ning)(ning)土進(jin)行(xing)(xing)涵(han)(han)(han)(han)(han)(han)洞施(shi)(shi)工(gong)在(zai)(zai)海內(nei)時(shi)一項新技(ji)術，金(jin)(jin)(jin)屬(shu)(shu)波(bo)紋管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)以其機能不亂、安裝利便、有利環保、造價低等(deng)長處迅速在(zai)(zai)公(gong)路施(shi)(shi)工(gong)中代替(ti)了(le)金(jin)(jin)(jin)屬(shu)(shu)筋(jin)混(hun)凝(ning)(ning)土施(shi)(shi)工(gong)的涵(han)(han)(han)(han)(han)(han)洞，發展遠景非常廣闊。在(zai)(zai)公(gong)路施(shi)(shi)工(gong)中，應(ying)用金(jin)(jin)(jin)屬(shu)(shu)波(bo)紋管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)代替(ti)金(jin)(jin)(jin)屬(shu)(shu)筋(jin)混(hun)凝(ning)(ning)土進(jin)行(xing)(xing)涵(han)(han)(han)(han)(han)(han)洞施(shi)(shi)工(gong)的歷(li)史已經有100多年(nian)了(le)。1896年(nian)，美國率提高前輩行(xing)(xing)波(bo)紋管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)通道、涵(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)的可(ke)行(xing)(xing)性研究。其后，在(zai)(zai)美國、加拿(na)大、澳大利亞等(deng)國的公(gong)路建設(she)中，均(jun)采(cai)用了(le)金(jin)(jin)(jin)屬(shu)(shu)波(bo)紋管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)進(jin)行(xing)(xing)涵(han)(han)(han)(han)(han)(han)洞的施(shi)(shi)工(gong)。1990年(nian)，日本(ben)高速公(gong)路設(she)計，規(gui)范制定了(le)波(bo)紋管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)設(she)計技(ji)術規(gui)范。
