| 9. | According as distortion harmonious condition of traction cable ' s anchorage on cable - suspended traveler , increasing amount of cable tension during casting concrete was computed , and under every key operating condition of casting concrete , traveler ' s frontend elevations were educed . we seriously controlled wenhui bridge ' s course of cantilever casting concrete by this method , which assured that the bridge ' s construction went on successfully . and then , it was discussed how to simulate the effect of prestressing force in spatial analysis
根据挂篮前端牵索锚固点处的变形协调条件建立了挂篮上混凝土浇筑过程中牵索索力的增加量，并推导了挂篮上混凝土浇筑过程中的各主要工况下挂篮前端标高的计算公式，对文晖大桥挂篮上混凝土浇筑过程中的牵索索力和挂篮前端标高进行了细致地控制，确保了混凝土浇筑的顺利进行，为整个主梁线形和索力的双控打下了良好的基础。 |
