| Abstract: | Influences of various parameters,such as concrete density,elastic modulus,the error of prestressing force,shrinkage and creep of concrete,and temperature change,on the linear and internal forces of the continuous rigid frame bridge were analyzed.The main parameters for construction control were determined.It suggests that the inherent stress friction test should be conducted to avoid the temperature influence in the construction process.Relevant conclusions can be used as references for the design and const... |
