Design and analysis of parameter sensitivity of prestressed concrete continuous beam bridge inconstruction control

During the construction control in order to better control the elevation, the need for sensitivity analysis of the design parameters, the sensitivity analysis of design parameter adjustment principle, so as to adjust the measured deflection and deflection calculation error of judgment, and for the cross section should be the main design parameters of stress sensitivity. This method can identify accurately fast parameter error during the bridge construction, and ensure the smooth and long construction Liang Qiao. To provide reference for construction control of this kind of bridge deflection.
