Abstract
KEYWORD: Continuous rigid frame bridge;The cantilever construction;Linear control;Stress monitoring ABSTRACT: Running is the cantilever method is adopted in the study of the construction of continuous rigid frame bridge construction monitoring.The bridge with high pier and large cross- border, narrow bridge deck and other characteristics, high construction requirement and great technical difficulties.According to these characteristics, an analysis of the mechanical characteristics of each construction stage.Establishing finite element model of each construction stage, compared with measured values of related parameters correction and error analysis.Thus established in this kind of bridge construction control, should be focusing on the deflection and stress monitoring, but also attaches great importance to the influence factors such as temperature, sunshine.
