摘要：In order to study the sensitivity of construction control of multi span PC continuous beam bridge with corrugated steel webs, taking the main bridge of Yesheng Yellow River Highway Bridge in Ningxia as an example, the space finite element analysis software is used to simulate the bridge and calculate the construction control. In the process, different values of the main parameters of the structure affect the degree of the linear and internal stress of the bridge. The calculation results show that the effects of shrinkage and creep of concrete roof and floor, segmental weight and temperature gradient on the deformation and stress of the main beam are obvious; the elastic modulus of the concrete has a certain degree of influence on the deformation and stress of the main beam, and the influence of the prestressing parameters is smaller. Therefore, in the process of construction control, the influence of shrinkage and creep of the concrete roof and floor shall be considered, the weight of the main beam shall be strictly controlled, and the effect of the measurement time and the temperature gradient effect shall be taken into account in the linear monitoring.
