本文以在建的欧洲某大桥主跨度172m连续梁悬臂浇注施工工程为例,介绍研究使用GQJS软件对大跨度连续梁施工控制过程进行模拟计算分析,对其施工过程中影响主梁线形控制的敏感性参数进行对比分析,根据各参数影响程度,确定一个或几个施工控制主要参数,作为施工控制过程中参数识别和分析的重点,此分析成果可供桥梁工程技术人员参考。 Taking the cantilever pouring construction project with a span of 172m as a major span of a major European bridge under construction as an example, this paper introduces how to use the GQJS software to simulate the construction control of long-span continuous girders and analyzes the influence on the linear control of the main girder during its construction According to the influence degree of each parameter, one or several main parameters of construction control are determined as the key points of parameter identification and analysis in the process of construction control. The result of this analysis can be used as a reference for bridge engineering technicians.
