Large span continuous beam bridge construction control content and method of Keywords: large span continuous beam bridge; construction control; Abstract: in our country, the suspension bridge, arch bridge, continuous rigid frame bridge and other aspects of research and practice has achieved good results, but for large span prestressed concrete continuous beam bridge construction control technology of the relatively few studies. So the research and application of large span prestressed concrete continuous beam bridge construction control technology has very practical significance in engineering. This paper first analyzes the influence of long-span bridges construction control factors, followed by the construction of the contents and methods of construction control, the control principle are elaborated. 1 Preface The construction of long span bridge to go through a complicated process, in this process will be a lot of certain and uncertain factors, leading to the bridge structure s actual status deviates from the theoretical calculation state. Therefore, the bridge construction control is the focus of the construction process by analyzing deviations which occur in the identification, identify problems and timely rectification, and the structure of the follow-up phase undertakes forecasting, make construction system is always in control. Effects of 2 factors in the construction control of [ 1] Large span continuous beam bridge construction control the main purpose is to make the actual construction condition and maximize the ideal design ( alignment and stress ) coincide. To achieve these goals, we must fully understand the construction state may deviate from the theoretical design status of all the factors, so as to implement effective control of the construction of have a definite object in view. 2.1 structure parameters [2 ] Regardless of the bridge construction control, the structure parameters are very important factors to consider, structural parameters control i
