地質勘察實踐水利水電工程論文

1水利水電工程(cheng)地質(zhi)勘察(cha)實(shi)踐理念問題

1.1辯證(zheng)唯物論觀(guan)點

某(mou)壩基夾層(ceng)雙側(ce)的(de)巖體側(ce)向抗滑效應(ying)比較(jiao)大,如果(guo)按照(zhao)既有的(de)規律,不進行考慮(lv)的(de)話就不符(fu)合壩基的(de)實(shi)際。但(dan)是,進行絕(jue)對地考慮(lv)的(de)話,也不一(yi)定非常(chang)合適。事實(shi)上,只要(yao)按照(zhao)正常(chang)的(de)辦法,將其作為安(an)全儲備(bei),而不參與壩基穩定計(ji)算(suan)就可以了。

1.2整體論觀點

每(mei)一個(ge)工(gong)程(cheng)地質問(wen)題都存在一定的(de)(de)(de)系(xi)(xi)統之中,只有采用系(xi)(xi)統分析(xi)法(fa)才能夠對其進行客觀的(de)(de)(de)分析(xi)和判斷。系(xi)(xi)統方法(fa)論認為,人們在研究(jiu)和解(jie)決系(xi)(xi)統問(wen)題時,僅僅重(zhong)視各(ge)要素(su)(su)自身的(de)(de)(de)可靠(kao)性(xing)是不夠的(de)(de)(de),而應(ying)當將重(zhong)點放在如何通過對具有必要可靠(kao)性(xing)的(de)(de)(de)諸(zhu)多要素(su)(su)的(de)(de)(de)優化組合,以達到(dao)系(xi)(xi)統的(de)(de)(de)整(zheng)體效應(ying)最(zui)佳,而并不追求(qiu)每(mei)個(ge)要素(su)(su)自身可靠(kao)性(xing)都達到(dao)最(zui)高等級。否(fou)則,工(gong)程(cheng)地質決斷就必然是偏于保守的(de)(de)(de)。

水利水電工程地質勘察論文

摘要:地質勘(kan)察是水(shui)(shui)利(li)水(shui)(shui)電(dian)工(gong)(gong)程(cheng)中最(zui)重要的(de)組成部分(fen)。以池湖溪工(gong)(gong)程(cheng)為例(li),結合工(gong)(gong)程(cheng)現(xian)場地質情況,采用GPS技術對地質勘(kan)察中的(de)實際應用進行了闡述,為確保(bao)水(shui)(shui)利(li)水(shui)(shui)電(dian)工(gong)(gong)程(cheng)建設的(de)順利(li)提(ti)供了保(bao)障。

地(di)質(zhi)(zhi)環境(jing)與水(shui)利(li)水(shui)電(dian)工(gong)(gong)程質(zhi)(zhi)量(liang)關系密切,其中水(shui)體(ti)和土體(ti)等因素,都可能對工(gong)(gong)程質(zhi)(zhi)量(liang)產生影響,因此(ci)地(di)質(zhi)(zhi)勘(kan)(kan)察工(gong)(gong)作(zuo)是(shi)水(shui)利(li)水(shui)電(dian)工(gong)(gong)程建(jian)設中必不可少的環節。水(shui)土、土體(ti)的勘(kan)(kan)察需(xu)要從多個角度開展(zhan),不能單方面(mian)地(di)進行勘(kan)(kan)察,因此(ci)面(mian)對不同勘(kan)(kan)察需(xu)求(qiu),需(xu)要采用相應的技術。同時,在勘(kan)(kan)察中需(xu)要結(jie)合技術規范以及實際條件來開展(zhan)工(gong)(gong)作(zuo),以保(bao)障各項(xiang)勘(kan)(kan)察結(jie)果的準(zhun)確性,否(fou)則將會給后續工(gong)(gong)作(zuo)造成誤導。以下就(jiu)GPS技術在水(shui)利(li)水(shui)電(dian)工(gong)(gong)程地(di)質(zhi)(zhi)勘(kan)(kan)察中的應用進行了分析。

動態設計信息化施工論文

論文摘要(yao):簡要(yao)剖析了(le)山區高速公路動態設(she)計與信息化施工概況、必要(yao)性(xing)、實施辦(ban)法、應運(yun)效果及存在問(wen)題,為(wei)工程管理、監理、設(she)計、施工人員(yuan)提供參考。

論文關鍵(jian)詞:動態設計信息化(hua)施工山區高速公路

1公路動態設(she)計與信息化施工(gong)概(gai)況

(1)高(gao)(gao)(gao)(gao)速公(gong)(gong)(gong)路(lu)(lu)建(jian)設概(gai)況。高(gao)(gao)(gao)(gao)速公(gong)(gong)(gong)路(lu)(lu)的(de)建(jian)設不僅是交通(tong)現(xian)代化(hua)的(de)重要標志(zhi)(zhi),也是國(guo)(guo)家現(xian)代化(hua)的(de)標志(zhi)(zhi)。自從(cong)1988年(nian)以來,我(wo)(wo)國(guo)(guo)高(gao)(gao)(gao)(gao)速公(gong)(gong)(gong)路(lu)(lu)建(jian)設快(kuai)(kuai)速發(fa)(fa)展(zhan),年(nian)通(tong)車里程(cheng)超(chao)過4000公(gong)(gong)(gong)里,到(dao)2004年(nian)底通(tong)車里程(cheng)超(chao)過3、4萬公(gong)(gong)(gong)里,位居世(shi)界(jie)第二(er)。高(gao)(gao)(gao)(gao)速公(gong)(gong)(gong)路(lu)(lu)的(de)發(fa)(fa)展(zhan)有(you)力地(di)推動(dong)了(le)(le)國(guo)(guo)民經濟的(de)發(fa)(fa)展(zhan)和(he)社會(hui)的(de)進(jin)步。當前我(wo)(wo)國(guo)(guo)已(yi)進(jin)入全面建(jian)設小康社會(hui)的(de)新(xin)時期(qi),對(dui)高(gao)(gao)(gao)(gao)速公(gong)(gong)(gong)路(lu)(lu)的(de)發(fa)(fa)展(zhan)提(ti)出了(le)(le)更(geng)高(gao)(gao)(gao)(gao)的(de)要求。為(wei)保障高(gao)(gao)(gao)(gao)速公(gong)(gong)(gong)路(lu)(lu)的(de)持(chi)續、健(jian)康、快(kuai)(kuai)速的(de)發(fa)(fa)展(zhan),交通(tong)部編制(zhi)了(le)(le)《國(guo)(guo)家高(gao)(gao)(gao)(gao)速公(gong)(gong)(gong)路(lu)(lu)網規劃》,由7條(tiao)首都放射線和(he)9條(tiao)南北(bei)線、18條(tiao)東西(xi)線組成,簡稱“7918網”,總規模(mo)約8.5萬公(gong)(gong)(gong)里,并于2004年(nian)12月17日經國(guo)(guo)務院審議通(tong)過,標志(zhi)(zhi)著中國(guo)(guo)高(gao)(gao)(gao)(gao)速公(gong)(gong)(gong)路(lu)(lu)建(jian)設進(jin)入一(yi)個新(xin)的(de)歷(li)史時期(qi)。

(2)山(shan)(shan)區高(gao)速(su)公(gong)路(lu)(lu)的特點(dian)。我國山(shan)(shan)區分(fen)布地(di)域(yu)廣闊,占國土面積70%以上,隨著公(gong)路(lu)(lu)建設發展,山(shan)(shan)區高(gao)速(su)公(gong)路(lu)(lu)所占比(bi)例越來越大。我國山(shan)(shan)區地(di)形(xing)條件困難,地(di)質構(gou)造復雜,地(di)質環(huan)境脆弱,地(di)質病(bing)害多,山(shan)(shan)區高(gao)速(su)公(gong)路(lu)(lu)建設特點(dian)是橋(qiao)隧多、路(lu)(lu)基(ji)高(gao)陡邊坡(po)多、規模與(yu)投(tou)資大,同時對生態環(huan)境的影響也大。目前,國家對山(shan)(shan)區高(gao)速(su)公(gong)路(lu)(lu)的建設也提出了(le)更(geng)高(gao)的要(yao)求(qiu),要(yao)把山(shan)(shan)區高(gao)速(su)公(gong)路(lu)(lu)建設成生態路(lu)(lu)、環(huan)保路(lu)(lu)、景觀路(lu)(lu),與(yu)自然融為(wei)一體。

(3)山(shan)(shan)區(qu)高速(su)公路(lu)(lu)動(dong)態(tai)(tai)設(she)(she)計(ji)(ji)與信息化(hua)施工(gong)(gong)現狀。目(mu)前山(shan)(shan)區(qu)高速(su)公路(lu)(lu)建設(she)(she)是(shi)勘(kan)測、設(she)(she)計(ji)(ji)、施工(gong)(gong)三步(bu)曲(qu)。我(wo)國東南(nan)沿海是(shi)多山(shan)(shan)地(di)(di)區(qu),路(lu)(lu)基高陡邊坡和(he)(he)(he)(he)隧道工(gong)(gong)程也比(bi)較多,由于山(shan)(shan)區(qu)地(di)(di)質復(fu)雜、地(di)(di)質病害(hai)(hai)多的客觀現實,在滑坡和(he)(he)(he)(he)高陡邊坡病害(hai)(hai)治(zhi)理實踐中(zhong),開展了預設(she)(she)計(ji)(ji)(地(di)(di)勘(kan)資料(liao))、高陡邊坡地(di)(di)質病害(hai)(hai)調查評(ping)估和(he)(he)(he)(he)防護加(jia)固工(gong)(gong)程方案。在施工(gong)(gong)過程中(zhong)根據地(di)(di)質條件的信息資料(liao),設(she)(she)計(ji)(ji)跟蹤進(jin)行(xing)動(dong)態(tai)(tai)設(she)(she)計(ji)(ji),調整修改,完善優(you)化(hua),然后進(jin)行(xing)旖(yi)工(gong)(gong)。在隧道工(gong)(gong)程中(zhong),根據圍巖類別(bie)的變(bian)化(hua)和(he)(he)(he)(he)不良(liang)的地(di)(di)質情況(kuang)調整原(yuan)設(she)(she)計(ji)(ji),指導施工(gong)(gong)。總(zong)體來說,動(dong)態(tai)(tai)設(she)(she)計(ji)(ji)與信息化(hua)施工(gong)(gong)仍處(chu)于一個摸索階段,尚無章可循。

數字化巖土勘探運用

巖(yan)(yan)土(tu)(tu)(tu)工(gong)程(cheng)勘察研究的(de)(de)對象是巖(yan)(yan)體(ti)(ti)和(he)土(tu)(tu)(tu)體(ti)(ti)。巖(yan)(yan)體(ti)(ti)在(zai)(zai)(zai)(zai)其形(xing)成和(he)存(cun)在(zai)(zai)(zai)(zai)的(de)(de)整個地(di)(di)質歷史過(guo)程(cheng)中,經(jing)(jing)受(shou)了(le)各(ge)種復雜的(de)(de)地(di)(di)質作(zuo)用(yong),因而(er)有(you)著復雜的(de)(de)結構和(he)地(di)(di)應力(li)場(chang)環境。而(er)不(bu)(bu)同地(di)(di)區(qu)的(de)(de)不(bu)(bu)同類型的(de)(de)巖(yan)(yan)體(ti)(ti),由于經(jing)(jing)歷的(de)(de)地(di)(di)質作(zuo)用(yong)過(guo)程(cheng)不(bu)(bu)同,其工(gong)程(cheng)性質往(wang)(wang)往(wang)(wang)具(ju)有(you)很大的(de)(de)差別。巖(yan)(yan)石出(chu)露地(di)(di)表后(hou),經(jing)(jing)過(guo)風(feng)化(hua)作(zuo)用(yong)而(er)形(xing)成土(tu)(tu)(tu),它們或留存(cun)在(zai)(zai)(zai)(zai)原地(di)(di),或經(jing)(jing)過(guo)風(feng)、水及冰川的(de)(de)剝蝕和(he)搬運作(zuo)用(yong)在(zai)(zai)(zai)(zai)異地(di)(di)沉(chen)積形(xing)成土(tu)(tu)(tu)層。在(zai)(zai)(zai)(zai)各(ge)地(di)(di)質時(shi)期各(ge)地(di)(di)區(qu)的(de)(de)風(feng)化(hua)環境、搬運和(he)沉(chen)積的(de)(de)動力(li)學條件均存(cun)在(zai)(zai)(zai)(zai)差異性,因此土(tu)(tu)(tu)體(ti)(ti)不(bu)(bu)僅(jin)工(gong)程(cheng)性質復雜而(er)且(qie)其性質的(de)(de)區(qu)域(yu)性和(he)個性很強(qiang)。

建筑工程中問題解析以及研究

一(yi)、工程質量(liang)問(wen)題措(cuo)施(shi)

出現施(shi)(shi)工質量(liang)問題(ti)的原(yuan)因影響(xiang)施(shi)(shi)工項目質量(liang)的因素很(hen)多,諸(zhu)如建(jian)筑(zhu)結構的錯位、傾斜(xie)、倒塌、破壞、開裂(lie)、滲水、漏水、剛度差、強度不足(zu)、斷(duan)面尺寸不精確等(deng),但(dan)究其原(yuan)因,可以歸納如下:

(1)違背(bei)建(jian)筑程(cheng)(cheng)序如不(bu)(bu)經可行性論證,不(bu)(bu)作(zuo)調查分析就(jiu)拍板定案;沒有搞清工(gong)(gong)(gong)程(cheng)(cheng)地(di)質(zhi)、水文地(di)質(zhi)就(jiu)倉(cang)促開工(gong)(gong)(gong);無證設計;無圖施(shi)(shi)工(gong)(gong)(gong);任意修改設計,不(bu)(bu)按圖施(shi)(shi)工(gong)(gong)(gong);工(gong)(gong)(gong)程(cheng)(cheng)竣(jun)工(gong)(gong)(gong)不(bu)(bu)進行試車運(yun)轉,不(bu)(bu)經驗收(shou)就(jiu)交付使用等(deng)若干現(xian)象(xiang),致使不(bu)(bu)少工(gong)(gong)(gong)程(cheng)(cheng)項(xiang)目留(liu)有嚴重(zhong)隱(yin)患,房屋倒塌事故也時有發(fa)生。

(2)工程地(di)(di)質(zhi)(zhi)勘察原因未認(ren)真(zhen)進行地(di)(di)質(zhi)(zhi)勘察,提供的(de)地(di)(di)質(zhi)(zhi)資料,數據有誤。論文(wen)百事通地(di)(di)質(zhi)(zhi)勘察時,鉆孔間距太(tai)大(da)(da),不(bu)能(neng)全面反(fan)映地(di)(di)基(ji)的(de)實際(ji)情況,如當基(ji)巖(yan)面起伏變化(hua)較大(da)(da)時,軟土(tu)層(ceng)厚(hou)薄相差亦甚大(da)(da);地(di)(di)質(zhi)(zhi)勘察鉆孔深度(du)不(bu)夠,沒有查地(di)(di)下軟土(tu)層(ceng)、滑坡、墓(mu)穴、孔洞等地(di)(di)層(ceng)構造;地(di)(di)質(zhi)(zhi)勘察報告不(bu)詳(xiang)細、不(bu)準確等,均會導致采用錯誤的(de)基(ji)礎方案,造成地(di)(di)基(ji)不(bu)均勻沉降(jiang)、失(shi)穩,使上(shang)部結(jie)構及墻體開裂、破壞、倒塌。

(3)未加固處(chu)(chu)理(li)好地(di)基對軟弱土(tu)(tu)、沖填(tian)土(tu)(tu)、雜填(tian)土(tu)(tu)、濕陷性黃(huang)土(tu)(tu)、膨脹土(tu)(tu)、巖(yan)(yan)層出(chu)露(lu)、溶(rong)巖(yan)(yan)、土(tu)(tu)洞等不(bu)均(jun)勻地(di)基未進(jin)行加固處(chu)(chu)理(li)或處(chu)(chu)理(li)不(bu)當(dang),均(jun)是導致重大質量(liang)問題的(de)原因(yin)。必須根據(ju)不(bu)同(tong)地(di)基的(de)工程特點,按照地(di)基處(chu)(chu)理(li)應(ying)與上部結構相結合,使其共同(tong)工作的(de)原則,從地(di)基處(chu)(chu)理(li)、設計(ji)措(cuo)施、結構措(cuo)施、防水措(cuo)施、施工措(cuo)施方(fang)面(mian)綜合考慮治理(li)。

(4)設計計算(suan)問(wen)題設計考慮(lv)不(bu)(bu)周,結構構造(zao)不(bu)(bu)合理,計算(suan)簡圖不(bu)(bu)正確,計算(suan)荷取值(zhi)過小,內力(li)分析有(you)誤,沉降縫及(ji)伸縮縫設置不(bu)(bu)當,懸挑結構未(wei)進行(xing)抗傾覆(fu)驗等(deng),都是(shi)誘發質(zhi)量(liang)問(wen)題的(de)隱患(huan)。如(ru)某擋土墻(qiang)工程(cheng)由于(yu)(yu)設計時(shi)未(wei)了(le)解(jie)清楚工程(cheng)地質(zhi)情(qing)況,施(shi)工時(shi)又未(wei)對現(xian)場(chang)情(qing)況進行(xing)核實,加(jia)上施(shi)工隊(dui)伍在基(ji)礎(chu)開挖時(shi)未(wei)能及(ji)時(shi)將現(xian)場(chang)地質(zhi)情(qing)況反饋給(gei)設計人員(yuan),因(yin)此,盡管上部結構設計、施(shi)工質(zhi)量(liang)良好,但因(yin)基(ji)礎(chu)設計不(bu)(bu)合理,以至于(yu)(yu)使用荷載(zai)尚未(wei)達到(dao)設計值(zhi)的(de)一(yi)半,擋土墻(qiang)就(jiu)(jiu)出現(xian)了(le)滑移和倒塌。又如(ru)某圓筒倉開裂事故,也是(shi)由于(yu)(yu)設計人員(yuan)疏(shu)忽,在試(shi)投產時(shi)就(jiu)(jiu)筒壁開裂,致使建筑物建成后不(bu)(bu)能滿足基(ji)本(ben)的(de)使用要求。
