Abstrakt:

At present, there is a lot of research on the structural system of the completion stage of the Kuihua arch bridge in China, but there is a lack of research on the risks existing in each stage of the construction of the Kuihua arch bridge. Therefore, it is necessary to conduct a full process simulation analysis of the construction process of the sunflower shaped continuous arch bridge. The following conclusions were drawn from this study: (1) After analysis, the construction method of first removing the support below the main arch ring and then pouring the main beam can ensure the safety of construction. (2) The maximum axial force of the support pole below the main arch is -17.67kN, located in rows 10 and 50. The maximum vertical displacement of the main arch is -4.998mm, which is much smaller than the allowable deflection. Therefore, the shape of the main arch is within the safe range. (3) The tensile stress of the main arch and continuous longitudinal beam are both less than the design value of C40 concrete tensile strength of 1.71MPa, so the main arch and continuous longitudinal beam have not cracked, and are in a safe state throughout the construction process.
