Analysis of Parameter Sensitivity in Construction Control of Inclined Pylon Cable-Stayed Bridge without Backstays

Abstract:

Parameter changes of a bridge in construction process must have an effect on its stress and alignment.And different parameters ,in the same bridge ,affect state of bridge to a different degree. While we have no need to consider every parameter in practical construction process, just paying attention to some sensitive parameters with a great effect on bridge structure instead .So a reseach of parameter sensibility of bridge construction is necessary to find out sensitive ones of all to limit their great effect .In this paper, based on JinZhou cable-stayed bridge without backstays,we use Midas civil to analyze the degree of impact of each parameter on stress and alignment of main girde ,which is depended on to put forward the main sensitive parameters of the bridge in construction process and a few of advice about its construction technology.
