近些年來我國城市地鐵建設迅速發展,盾構施工法作為一種安全而又環保的施工方法得到了廣泛的使用,另外在黃浦過江隧道,西氣東輸的穿黃隧道等工程也在使用盾構隧道施工技術。這其中土壓平衡式盾構在我國的使用最為普遍,成為地鐵隧道施工技術的主流。土壓平衡式盾構施工成功的關鍵是要將開挖面切削下來的土體在壓力艙內調整成一種「塑性流動狀態」 。Particularly four following respect problems of main research of this thesis : first, excavating and optimizing of the road bed and the slope protect, on the basis of influence factor analysis and the slope design principle by the expressway of mountain area of limestone, we excavate the model of optimizing after putting forward the road bed which is suitable for the expressway of mountain area of limestone, through employ this optimize model, we can reduce the amount of road bed excavate, thus maximum reducing slope excavate destruction to environment and pollute ; according to limestone mountain area expressway characteristic of the cutting slope, we use the law of finite element and rmr of revision carry on stability analyze and appraise to their side slope ; combine the limestone rock body characteristic of mountain area, we have analyzed the corresponding side slope safeguard procedures
論文主要研究了以下四方面問題:第一,路基開挖優化。在分析石灰巖山區環境特徵的基礎上,探討了石灰巖山區路線設計的原則與方法;在應用有限元數值分析方法對邊坡的開挖穩定性進行分析的基礎上,提出了陡開挖強支護的石灰巖山區高速公路的路基開挖方式,並建立了填挖平衡,開挖面積最小的石灰巖山區高速公路的路基開挖量優化模型;結合石灰巖山區巖體特性,探討分析了相應的邊坡防護措施。第二,土石方處理及自然水系調治恢復。Severe protests from local residents living along mrt routes during the route alignment coordination caused a two - year delay to the proposed schedule for the hsingchuang line. therefore, to reduce the extent of tunneling is a key consideration in the long - term planning of mrt routes. other downsides to the single tunneling method are that it requires longer construction time, and that two break throughs from the tunnel to the work shaft involve a higher construction risk
另因採用單孔潛盾隧道須鉆掘上、下行隧道,除施工時程較長外,且兩次破鏡將增加施工之風險,故有鑒于潛盾機之技術日新月異,國外已有採用多圓形潛盾工法( mf工法)之成功案例,此除可減少用地徵收補償之困擾外,且可減少隧道開挖面積進而減少棄土所造成之問題。分享友人
