| Abstract | The invention discloses an incremental cable adjusting method considering the cable-beam temperature difference effect for a concrete cable-stayed bridge. The incremental cable adjusting method comprises the following steps: finite element analysis of the overall concrete cable-stayed bridge, cable force and temperature measurement, cable force conversion considering temperature, and incremental cable adjustment; before cable adjustment, a time period during which the temperature is relatively stable is selected, the cable force and the cable-beam temperature of the overall bridge are measured, and the cable force of the overall bridge equated at the temperature of 20 DEG C is taken as the reference cable force for cable adjustment; during the cable adjustment process, the increment of the cable force is taken as the controlled quantity, the most sensitive cross section displacement value of the main span is taken as the verification quantity; after completion of all the processes, the cable-beam temperature |
