Abstract
This paper aims to investigate the effect of the thickness of concrete poured in stages on the force conditions of the supersized block 0 bracket.Based on the construction of the main beam block 0 of a large-span continuous rigid frame bridge in progress,the study is performed by establishing a three-dimensional model with a supersized block 0 bracket involved by pouring concrete in stages by using Mi-das Civil finite element software,conducting the force analysis on the model under different load combi-nations,and evaluating its force state and safety performance under different working conditions.The re-sults indicate that the segmented pouring thicknesses of 7.0 and 14.2 m determined by the theoretical calculation meet the actual construction needs;and the supersized block 0 bracket structure with concrete poured in stages and subjected to stress,in which the bearing capacity,deformation,and overall stability all meet the normative requirements of on-site construction,ensuring the construction quality of block 0 concrete and saving the amount of bracket materials.At the same time,it also provides theoretical refer-ence for the design of similar block 0 brackets.关键词
