【文章內(nèi)容簡(jiǎn)介】 準(zhǔn)，但是由于財(cái)政問題，這個(gè)設(shè)計(jì)在重新恢復(fù)之前曾經(jīng)被暫停了七年。 In 2021, the project has been listed in the target engineering and design work, development and design bidding announced formally. This work again awarded JSC institute. Reconstruction program in pletion by the end of 2021 and is national review mittee actively receiving。 The construction work will begin in the end of that year. 2021 年，該項(xiàng)目被列入目標(biāo)工程和方案設(shè)計(jì)工作，開發(fā)設(shè)計(jì)招標(biāo)正式公布。這項(xiàng)工作又一次被授予了 JSC 研究所。重建計(jì)劃在 2021 年底完成并且被國家審查委員會(huì)積極地接收；建設(shè)工作就在當(dāng)年年底開始。 The technical feasibility and economic applicability, on the basis of parison of bridge structure concept won approval. A main limit the upper structure height bridge is strict limits. On the one hand, in order to navigation, Bridges must maintain certain bridge headroom, on the other hand, LaZaLieFu deck height was admiral limits, to the protection of cultural relics, bridge deck height can39。t improve. 在進(jìn)行技術(shù)可行性和經(jīng)濟(jì)適用性比較的基礎(chǔ)上，大橋的結(jié)構(gòu)概念獲得了認(rèn)可。一個(gè)主要的限制是橋梁上部結(jié)構(gòu)高度的嚴(yán)格限制。一方面，為了通航，橋梁必須保持一定的橋下凈空，另一方面，橋面高度又被拉扎列夫海軍上將限制，為了保護(hù)文物 ，橋面高 4 度不能提高。 In order to satisfy these is almost contradictory condition, the deck longitudinal profile only curve radius 1000m, the only way to meet all the conditions. But even if adopted this minimal profile radius, the strict requirements on bridge deck height of the maximum height makes only m. This condition can be through a classic 5 span continuous beam or staycables system to solve. The two solutions, but the cost is almost the same cablestayed bridge, because more promising scheme from building exterior to see it more attractive. Another advantage is that it can reduce construction time, because there is no need to build in the riverbed pier. 為了滿足這些幾乎是相互矛盾的條件，橋面縱向剖面的曲線半徑只能為 1000m，只有這樣才能滿足所有的條件。但是即使采用了這種最小的剖面半徑，關(guān)于橋面高度的苛刻要求使得橋面的最大高度只能為 。這個(gè)條件可以通過一個(gè)經(jīng)典的五跨連續(xù)梁或者斜拉索體系來解決。這兩個(gè)方案的 費(fèi)用幾乎相同，但是斜拉橋的方案更被看好，因?yàn)閺慕ㄖ庥^來看它更有吸引力。另外一個(gè)好處是，它可以減少施工時(shí)間，因?yàn)闆]有必要將橋墩建在河床上。 This unusual shape, structure, especially the shape of the tower and asymmetry of single span layout, the engineers from the institute of design at JSC ability request, asking them to deal with problems of nonstandard. One of the problems is, must provide the necessary stiffness for pavement, and minimize pylon foundation39。s weight and maintain balance system. 這種非常規(guī)的外形結(jié)構(gòu) ,特別塔的形狀和它的不對(duì)稱的單跨布局 ,對(duì)來自 JSC 研究所的工程師的設(shè)計(jì)能力提出要求 ,要求他們處理非標(biāo)準(zhǔn)的問題。其中一個(gè)問題是，必須為路面 提供必要的剛度，同時(shí)最大限度地減少塔基礎(chǔ)的重量和維持系統(tǒng)平衡。 So in construction, a single span cablestayed bridge GangDa choose carriageways steel deck plate and orthotropic board.
