According to the design theory of the cable - stayed bridge and to the feature of the cantilever construction the authors propose a construction control method called optimum completion state method ( ocsm ) for rc cable - stayed bridges in the proposed method, the optimum completion state is regarded as the final target of the construction control, and the optimum construction state at each construction stage is taken as the technical route the key of the method is to properly choose or adjust the cable forces the objectives function of optimization is to minimize the elevation error of the girder under the constraint condition that the internal forces ( bending moments ) of the girder are bounded the optimization variables are the cable forces on the basis of the above principles, a optimum model for a construction step is established and cable force adjustments can be found for each construction step in this model, the creep and shrinkage effects of concrete have been considered a bridge example is given which shows that the final state of the bridge is very close to the design aim and that this method is much better than the so - called double - control method the example is a good illustration of the soundness and practical value of the proposed method
根據現代斜拉橋結構設計理論和懸臂施工方法的特點，提出了以最佳成橋狀態作為施工控制的最終目標，以實施最佳施工階段為技術路線，以索力調整為核心內容的斜拉橋施工控制理論，簡稱為最佳成橋狀態法；以斜拉橋主梁標高誤差最小為目標函數，以主梁內力（彎矩）為約束條件，以索力為優化變量，建立了最佳施工階段的索力調整計算模型；推導了考慮徐變收縮效應的索力調整計算公式；用最佳成橋狀態法對一實橋工程進行了施工控制全過程計算研究，得到的成橋狀態與設計目標相當接近，優于該橋以「雙控」為控制目標的實測結果，有力地證明了本文方法的正確性及其工程實際價值
