路橋工程技術研究
1基礎內容介紹
大(da)(da)家或許對路(lu)橋(qiao)(qiao)工程(cheng)并(bing)不是(shi)很了解。路(lu)橋(qiao)(qiao)主要包括(kuo)兩方(fang)面的(de)種(zhong)類:第一(yi)種(zhong)是(shi)板(ban)式(shi)橋(qiao)(qiao)。板(ban)式(shi)橋(qiao)(qiao)在(zai)我(wo)們(men)的(de)日常生活(huo)幾乎所處可見(jian),它的(de)承載量相對來說比(bi)較(jiao)大(da)(da),在(zai)高(gao)速公(gong)路(lu)等(deng)地方(fang)多有采用;第二種(zhong)是(shi)梁(liang)式(shi)橋(qiao)(qiao)。梁(liang)式(shi)橋(qiao)(qiao)在(zai)國外和(he)國內(nei)一(yi)些較(jiao)發達的(de)城市也是(shi)比(bi)較(jiao)常見(jian)的(de)。比(bi)如松花(hua)江大(da)(da)橋(qiao)(qiao)等(deng),都是(shi)屬(shu)于梁(liang)式(shi)橋(qiao)(qiao)的(de)范圍。對以(yi)上這(zhe)兩種(zhong)橋(qiao)(qiao)的(de)建(jian)設被稱(cheng)為(wei)(wei)是(shi)路(lu)橋(qiao)(qiao)工程(cheng)。而在(zai)建(jian)設的(de)過程(cheng)中所采用的(de)技術被稱(cheng)為(wei)(wei)路(lu)橋(qiao)(qiao)工程(cheng)技術。
2我國現(xian)階(jie)段路(lu)橋工程技術存在的問題分(fen)析(xi)
2.1施(shi)工(gong)(gong)(gong)人(ren)員技(ji)術水(shui)平偏(pian)低(di)。不得不承認,現(xian)階(jie)段我(wo)國路(lu)橋(qiao)(qiao)工(gong)(gong)(gong)程(cheng)(cheng)技(ji)術還是(shi)(shi)(shi)存(cun)在(zai)一(yi)(yi)(yi)定的(de)(de)(de)問題(ti)的(de)(de)(de)。問題(ti)主(zhu)要表(biao)現(xian)在(zai)幾個方面。第一(yi)(yi)(yi)就是(shi)(shi)(shi)施(shi)工(gong)(gong)(gong)人(ren)員技(ji)術水(shui)平偏(pian)低(di)的(de)(de)(de)問題(ti)。專業(ye)的(de)(de)(de)路(lu)橋(qiao)(qiao)工(gong)(gong)(gong)程(cheng)(cheng)技(ji)術施(shi)工(gong)(gong)(gong)人(ren)員相對(dui)(dui)來說(shuo)所需要花費的(de)(de)(de)工(gong)(gong)(gong)資比較(jiao)多,為了節約一(yi)(yi)(yi)定的(de)(de)(de)資金(jin)支持,一(yi)(yi)(yi)些(xie)建筑商在(zai)進行路(lu)橋(qiao)(qiao)工(gong)(gong)(gong)程(cheng)(cheng)建設的(de)(de)(de)過程(cheng)(cheng)中,所雇傭的(de)(de)(de)路(lu)橋(qiao)(qiao)工(gong)(gong)(gong)程(cheng)(cheng)技(ji)術人(ren)員相對(dui)(dui)來說(shuo)只是(shi)(shi)(shi)普通的(de)(de)(de)百姓(xing),有些(xie)人(ren)甚至(zhi)并不具備專業(ye)的(de)(de)(de)路(lu)橋(qiao)(qiao)工(gong)(gong)(gong)程(cheng)(cheng)技(ji)術知識(shi)。這(zhe)就意味著,路(lu)橋(qiao)(qiao)工(gong)(gong)(gong)程(cheng)(cheng)技(ji)術施(shi)工(gong)(gong)(gong)團(tuan)隊并不是(shi)(shi)(shi)一(yi)(yi)(yi)個素質較(jiao)高的(de)(de)(de)團(tuan)隊。
2.2管理(li)(li)制度(du)不完善(shan)。管理(li)(li)制度(du)不完善(shan)也是(shi)(shi)路橋(qiao)工程技術(shu)(shu)所需要(yao)面臨(lin)的(de)問題之一。技術(shu)(shu)也是(shi)(shi)需要(yao)一定(ding)的(de)管理(li)(li)的(de)。因為(wei)技術(shu)(shu)的(de)實施(shi)主體(ti)是(shi)(shi)人。如果不采(cai)取一定(ding)的(de)措施(shi)對(dui)路橋(qiao)工程技術(shu)(shu)施(shi)工主體(ti)進行必(bi)要(yao)的(de)管理(li)(li)。那么將會引發一系(xi)列的(de)問題。然而,我國現階段(duan)路橋(qiao)工程技術(shu)(shu)存在的(de)問題就是(shi)(shi)缺乏完善(shan)的(de)管理(li)(li)制度(du)。
2.3施工(gong)(gong)(gong)材(cai)(cai)料的(de)質量達(da)不到(dao)標(biao)準。施工(gong)(gong)(gong)材(cai)(cai)料達(da)不到(dao)質量標(biao)準也是需要考慮以及面對的(de)問題之一。在開展路(lu)橋工(gong)(gong)(gong)程(cheng)技(ji)術的(de)過程(cheng)中,是需要材(cai)(cai)料的(de)支持的(de)。如(ru)果所使用的(de)材(cai)(cai)料沒能夠達(da)到(dao)相應的(de)標(biao)準的(de)話,那么路(lu)橋工(gong)(gong)(gong)程(cheng)技(ji)術是無(wu)法發(fa)揮它的(de)水平(ping)的(de)。這(zhe)也就意味著,建筑施工(gong)(gong)(gong)材(cai)(cai)料將(jiang)會直接的(de)影響(xiang)到(dao)路(lu)橋工(gong)(gong)(gong)程(cheng)技(ji)術的(de)發(fa)揮。

從建(jian)(jian)筑學的(de)角(jiao)度來看(kan),道(dao)(dao)路橋梁(liang)的(de)施(shi)工是其中最(zui)為困難(nan)的(de),因為其會受到(dao)(dao)很(hen)多方面(mian)的(de)因素的(de)干擾,以至(zhi)于(yu)不(bu)能夠跟隨著計劃方案的(de)進(jin)度進(jin)行。道(dao)(dao)路橋梁(liang)工程作為我國城市化建(jian)(jian)設的(de)基礎(chu)建(jian)(jian)設,只有當道(dao)(dao)路橋梁(liang)工程建(jian)(jian)設好之后(hou),才能夠保(bao)障當地的(de)交通運輸行業得到(dao)(dao)良好的(de)發(fa)展,提高(gao)人們(men)的(de)生活質量,從而帶動經濟的(de)可持續發(fa)展。因此,我們(men)應該加(jia)強(qiang)對公路橋梁(liang)施(shi)工技術的(de)研究(jiu),從而對其不(bu)斷改(gai)進(jin),保(bao)證施(shi)工的(de)質量。

2公路橋(qiao)梁施工技(ji)術的有效改進措施
公路橋梁高墩施工技術論文
1公路橋梁高(gao)墩施工的(de)特點
1.1周期長
橋墩(dun)為公路(lu)橋梁(liang)(liang)下部承載(zai)結構,需(xu)要(yao)承受橋梁(liang)(liang)上(shang)部結構的(de)(de)水(shui)平和豎向荷載(zai),是維持整個橋梁(liang)(liang)工(gong)程(cheng)(cheng)(cheng)穩定性的(de)(de)重要(yao)保障。橋墩(dun)設(she)(she)計與(yu)施(shi)工(gong)質量是影(ying)響工(gong)程(cheng)(cheng)(cheng)建(jian)設(she)(she)效果的(de)(de)關鍵因素(su),一旦(dan)橋墩(dun)出現失穩現象,很有可能會造成橋梁(liang)(liang)坍(tan)塌(ta)。高(gao)墩(dun)施(shi)工(gong)技術應用于公路(lu)橋梁(liang)(liang)工(gong)程(cheng)(cheng)(cheng)中時(shi),一般混凝(ning)土澆(jiao)筑高(gao)度均在3m左右,實際高(gao)度則可以(yi)達到30m,想要(yao)完(wan)成一座高(gao)墩(dun)澆(jiao)筑需(xu)要(yao)進(jin)行10多次(ci)作(zuo)業(ye),決定了其施(shi)工(gong)周期長(chang)的(de)(de)特(te)點(dian)[1]。再加上(shang)機械設(she)(she)備等因素(su)限制,很多高(gao)墩(dun)施(shi)工(gong)時(shi)間會達到30d以(yi)上(shang)。
1.2要求高
高墩(dun)作(zuo)(zuo)(zuo)為(wei)公路(lu)橋梁(liang)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)的(de)重要組(zu)成部分,其(qi)施(shi)(shi)工(gong)(gong)(gong)效果在很大(da)程(cheng)(cheng)(cheng)度上決定了工(gong)(gong)(gong)程(cheng)(cheng)(cheng)結構的(de)穩(wen)定性(xing)與安全性(xing)。但是(shi)高墩(dun)施(shi)(shi)工(gong)(gong)(gong)技術操作(zuo)(zuo)(zuo)難(nan)度大(da),再加(jia)上工(gong)(gong)(gong)程(cheng)(cheng)(cheng)施(shi)(shi)工(gong)(gong)(gong)環境特殊,整(zheng)個施(shi)(shi)工(gong)(gong)(gong)過(guo)程(cheng)(cheng)(cheng)很容(rong)易受外部因(yin)素(su)干擾,稍有不當,便(bian)會因(yin)為(wei)操作(zuo)(zuo)(zuo)不規范而出(chu)現質量隱患。為(wei)保(bao)證施(shi)(shi)工(gong)(gong)(gong)質量滿足(zu)規范和(he)(he)標準的(de)要求,需(xu)要重點控(kong)制(zhi)好施(shi)(shi)工(gong)(gong)(gong)技術和(he)(he)工(gong)(gong)(gong)藝,提前根(gen)據現場特點編制(zhi)科(ke)學合理的(de)施(shi)(shi)工(gong)(gong)(gong)方案,作(zuo)(zuo)(zuo)為(wei)后續各(ge)階段作(zuo)(zuo)(zuo)業實施(shi)(shi)的(de)依據,確(que)保(bao)滿足(zu)施(shi)(shi)工(gong)(gong)(gong)要求。

1.1路橋(qiao)建設項目(mu)管理的(de)涵義(yi)
通(tong)常情況下,對于(yu)路(lu)橋建(jian)設工(gong)程(cheng)項目(mu)(mu)(mu)實行(xing)(xing)的(de)(de)管(guan)理是指(zhi)對該項目(mu)(mu)(mu)整體(ti)的(de)(de)完工(gong)考評、執(zhi)行(xing)(xing)以及計(ji)劃(hua)等階段(duan)(duan)的(de)(de)管(guan)理和控制,具體(ti)劃(hua)分(fen)的(de)(de)話可以分(fen)為初始階段(duan)(duan)、執(zhi)行(xing)(xing)階段(duan)(duan)以及結(jie)束階段(duan)(duan)三部分(fen)。在(zai)初始階段(duan)(duan)中,需要根據自身實際情況做好相(xiang)關的(de)(de)準(zhun)備(bei)工(gong)作(zuo),制定好相(xiang)應的(de)(de)施工(gong)方案。執(zhi)行(xing)(xing)階段(duan)(duan)則(ze)是對具體(ti)的(de)(de)路(lu)橋施工(gong)過(guo)程(cheng)予以指(zhi)導和管(guan)理,保(bao)證施工(gong)過(guo)程(cheng)的(de)(de)質(zhi)量(liang),對于(yu)施工(gong)過(guo)程(cheng)中出現(xian)的(de)(de)意外狀況和問題予以及時(shi)解(jie)決,促成(cheng)路(lu)橋建(jian)設的(de)(de)順利進行(xing)(xing)并達(da)成(cheng)最(zui)終的(de)(de)目(mu)(mu)(mu)標。而結(jie)束階段(duan)(duan)則(ze)是對路(lu)橋工(gong)程(cheng)進行(xing)(xing)后續(xu)的(de)(de)善后、評價(jia)以及總結(jie)工(gong)作(zuo),確保(bao)路(lu)橋建(jian)設的(de)(de)質(zhi)量(liang)能夠得到相(xiang)應的(de)(de)規(gui)范和標準(zhun)。簡而言之,路(lu)橋建(jian)設項目(mu)(mu)(mu)管(guan)理屬于(yu)一個動態的(de)(de)過(guo)程(cheng),各(ge)環節(jie)之間緊密(mi)相(xiang)連,只有做好各(ge)細(xi)節(jie)上的(de)(de)工(gong)作(zuo),才能確保(bao)工(gong)程(cheng)的(de)(de)最(zui)終質(zhi)量(liang)。
