高墩大跨连续刚构桥施工监测与控制

Construction Monitoring and Control of High Pier and Large Span Continuous Rigid Frame Bridge

以清水江大桥项目为背景,从施工监测和施工控制两个方面对连续刚构桥在施工过程中遇到的问题进行探究。对桥梁施工监测的内容进行了总结,分析了线性监测、截面应力监测、温度监测等操作的重要性和必要性。介绍了桥梁施工线性控制、应力控制和稳定性控制的原理和方法,并对影响施工控制的因素以及施工控制的方法进行分析。

Taking Qingshuijiang Bridge Project as background,this paper explores the problems encountered during construction of continuous rigid frame bridge from two aspects of construction monitoring and construction control.At the same time,this paper summarizes the contents of bridge construction monitoring,and analyses the importance and necessity of linear monitoring,section stress monitoring,temperature monitoring and other operations.Principles and methods of linear control,stress control and stability control of bridge construction are also introduced,and factors influencing construction control and methods of construction control are analyzed.
