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
