中文拼音 [shìdiàosuǒ]
纜式吊索
英文
cable sling-
Abstract : through the geometric factor analysis of main cable in erection, the calculation formula of internal force of main cable is given and the analysis method of main cable safety is also discussed in detail
文摘:通過對纜索吊裝設備主索的幾何因素分析，給出了主索的內力計算與驗算公式，結合示例詳細介紹了主索安全度分析方法。There are many materials and members to be hoisted during construction of the suspension bridge, unfortunately, the out - spread overhead curved cable makes it impossible for hoisting the stiffening girder with normal cable - supported lift. in order to ensure the construction proceeded smoothly, a multifunctional overhead cableway system is developed, thus accommodating all the hoisting tasks for the superstructure ( stiffening girder )
懸索橋施工中需要吊裝的材料和構件很多，豐都長江大橋懸索橋主纜採用空間外張式，使加勁梁的吊裝不能採用一般的纜載吊機形式，為使施工的順利進行，本橋施工中開發了多功能高架索道施工方案，以一副索道完成了多種工作，全面解決了上部結構（包括加勁梁）的多項吊裝作業。Abstract : cable - stayed is used to cable suspension, but cable force is calculated by manual, and only for less than 5 segments, and the prescion is poor. this paper puts forward “ zero moment method ”, which can not only calculate more segmental soupe force, but both temporary joint and fixed joint during construction. the mechanical concept is clear, and it is easy for calculating. it is fit for program, and the illustrations prove that the methods are right
文摘:斜拉扣掛在纜索吊裝中經常運用，但扣索索力多採用手工計算，且多用於5段以內的吊裝，計算復雜，精度低.本文提出「零彎矩法」 ，可計算任意多段扣索索力，既可計算拱肋在施工過程中各節段臨時鉸接，又可計算各節段固結的情況，將兩種連接方式統一成一種計算方法，力學概念清楚，計算簡便，適宜程，文中最後用示例證實本方法的正確性In addition, the analysis and test for the entire stability and limited carrying capacity are completed and results show that pingsheng bridge is also safe enough. 4. the influence on the static performance for pingsheng bridge of structural parameters, such as rise - span ratio of main cable, stiffened girder rigidity, main tower rigidity and main cable rigidity, is studied
對平勝大橋和與之具有相同結構參數的地錨式懸索橋模型進行了動力特性分析，並研究了主纜矢跨比、恆載集度、加勁梁剛度、主塔剛度、主纜抗拉剛度、吊索抗拉剛度等結構參數變化對兩類懸索橋動力特性的影響。分享友人
