摘要
以某刚构斜拉组合桥为工程背景,提出该类桥型施工监控的主要原则和方法,建立三维空间有限元模型对其施工全过程进行仿真分析,重点介绍了现场实测方案,并将理论计算值与工程现场实测值进行对比分析.实践研究表明,该刚构斜拉组合桥施工监控过程中所采用的监控流程和技术措施具有很强的实用性,可为同类型组合桥梁的施工控制提供参考.
Based on the project of a rigid-frame and cable-stayed composite bridge, the principles and methods for the construction monitoring of this kind of projects are proposed. And a three-dimensional space finite element model is built to simulate and study the whole process of the construction. This paper also emphatically introduces a field measurement scheme, and compares and analyzes the calculated value with the field measured results. The practical research indicates that the monitoring procedure and technique measures employed in the monitoring process are highly practical and can provide reference for the construction of composite bridges of this kind.
