金屬(shu)波(bo)紋(wen)(wen)(wen)涵(han)(han)(han)(han)管(guan)按地中構(gou)造物使用(yong)時,土(tu)體(ti)和波(bo)形(xing)(xing)鋼(gang)板(ban)(ban)有(you)合成作用(yong)能承(cheng)受(shou)外部載(zai)荷,因此金屬(shu)波(bo)紋(wen)(wen)(wen)涵(han)(han)(han)(han)管(guan)及土(tu)體(ti)共同承(cheng)受(shou)載(zai)荷的作用(yong)。金屬(shu)波(bo)紋(wen)(wen)(wen)管(guan)涵(han)(han)(han)(han)也叫波(bo)紋(wen)(wen)(wen)管(guan)涵(han)(han)(han)(han)或(huo)鋼(gang)制波(bo)紋(wen)(wen)(wen)涵(han)(han)(han)(han)管(guan),是指鋪埋在(zai)公(gong)路,鐵(tie)路下面(mian)的涵(han)(han)(han)(han)洞(dong)用(yong)螺紋(wen)(wen)(wen)波(bo)紋(wen)(wen)(wen)管(guan),它是由波(bo)形(xing)(xing)金屬(shu)板(ban)(ban)卷制成或(huo)用(yong)半圓波(bo)形(xing)(xing)鋼(gang)片拼(pin)制成的圓形(xing)(xing)波(bo)紋(wen)(wen)(wen)管(guan),應用(yong)于公(gong)路,鐵(tie)路,小(xiao)橋,通道,擋土(tu)墻(qiang)以(yi)及各種礦場,巷道擋墻(qiang)支護等工程中的涵(han)(han)(han)(han)洞(dong)(管(guan))

金屬波(bo)紋(wen)涵(han)(han)(han)管(guan)具有(you)施(shi)工(gong)工(gong)期短、造價(jia)低、對(dui)(dui)地(di)基擾動(dong)小(xiao)、對(dui)(dui)基礎要求低、適應變(bian)形機能好等(deng)長(chang)處,特(te)別合用于邊遠(yuan)地(di)區和多年凍(dong)土、軟土等(deng)特(te)殊(shu)地(di)基區域的(de)(de)道(dao)路(lu)涵(han)(han)(han)洞(dong)工(gong)程.目前,作為(wei)(wei)一種新型的(de)(de)道(dao)路(lu)涵(han)(han)(han)洞(dong)形式(shi).對(dui)(dui)鋼(gang)波(bo)紋(wen)管(guan)涵(han)(han)(han)洞(dong)進行野(ye)外(wai)現(xian)場(chang)力(li)學(xue)機能測(ce)試(shi)存在(zai)很多局(ju)限(xian)性,為(wei)(wei)了克服其局(ju)限(xian)性,本(ben)文在(zai)鋼(gang)波(bo)紋(wen)管(guan)涵(han)(han)(han)洞(dong)野(ye)外(wai)現(xian)場(chang)力(li)學(xue)機能測(ce)試(shi)的(de)(de)基礎上,利用有(you)限(xian)元力(li)學(xue)分析程序對(dui)(dui)鋼(gang)波(bo)紋(wen)管(guan)涵(han)(han)(han)洞(dong)的(de)(de)受力(li)變(bian)形作計(ji)算(suan)分析,將計(ji)算(suan)結果和野(ye)外(wai)現(xian)場(chang)實(shi)測(ce)值進行比較分析,建立公道(dao)的(de)(de)有(you)限(xian)元力(li)學(xue)模型,運用有(you)限(xian)元法(fa)系統地(di)分析鋼(gang)波(bo)紋(wen)管(guan)涵(han)(han)(han)洞(dong)的(de)(de)力(li)學(xue)機能成(cheng)為(wei)(wei)可(ke)行. 

鋼波紋涵管

鋼波紋涵管設計步(bu)驟結構分析:本圖假定波紋管和(he)土(tu)體均為(wei)彈(dan)性體。不考慮(lv)涵洞頂土(tu)柱和(he)附近填土(tu)間的摩擦(ca)力,采(cai)用角(jiao)度分布法(fa)計算(suan),半無窮彈(dan)性體理論核(he)算(suan)。土(tu)重(zhong)(zhong):按土(tu)柱重(zhong)(zhong)理論計算(suan),內摩擦(ca)角(jiao)φ=30°,土(tu)容量18KN/ m3.

金(jin)屬波紋(wen)涵(han)管也叫(jiao)波紋(wen)管涵(han),是指鋪埋在(zai)馬路(lu)、鐵路(lu)下(xia)的涵(han)洞(dong)(dong)用螺絲扣(kou)波紋(wen)管,它(ta)是由波形金(jin)屬板卷制(zhi)成(cheng)或用半圓波形鋼片拼制(zhi)成(cheng)的圓形波紋(wen)管。應用于馬路(lu)、鐵路(lu)、小橋、通(tong)道、擋土墻以及各種礦場巷道擋墻支護等工程中的涵(han)洞(dong)(dong)(管)。
