大跨连续刚构桥施工线形控制技术

Linear Construction Supervision Control Technology of Long Span Continuous Rigid Frame Bridge

通过对大跨径预应力混凝土连续刚构梁桥施工过程中结构的线形测试,经过合理结构分析计算,研究其施工过程中的线形变化规律,并根据现场实测数据和采用有效控制方法,给出合理的立模标高,使大桥顺利合龙。

This paper researched the linear variation law during the construction of the long span prestressed concrete continuous rigid frame bridge by linear testing and rational structural calculation analysis.And a reasonable elevation of formwork erection is given by the site real-test data and effective methods of control in order to close the bridge successfully.
