| As the massive construction of a variety of the long-span prestressed concrete continuous rigid frame bridge both in China and foreign countries, the control and management of construction procedure of continuous rigid frame bridge become a necessary guarantee of safety and quality during the bridge construction process. Besides, the stress and linear control theory applied in the construction process has also become more mature. Based on the supervision of the construction of the Banan high-speed Jialing River Bridge with the span of95+180+95m, this paper intends to analyze the supervising theories as well as the construction practice, aiming to find out the factors that affect the control of the construction of the long-span prestressed concrete continuous rigid frame bridge via sensitivity analysis. These findings will lead to more precise prediction and control of the actual stress and deformation in the construction process. The content of this thesis is as follows:Summary of bridge construction control theory;Computer simulation analysis of construction process;Sensitivity analysis of the main design parameters that affect construction supervision;Analysis and parameter identification of construction site monitoring results;In addition, this thesis is going to conclude and analyze the limitations of the application and propose appropriate improving measures. Based on the implementation of these improving measures and the Laboratory test and field test, it can be concluded that the improving measures are actually viable in practice. This new type of telescopic device could improve driving comfort to its maximum. Therefore, this research will generate innovative ideas for the future study of the telescopic device design. Futhermore, the findings will be a valuable reference frame for the relevant research in the future, which could create recognizable social value. |
