G318(西藏境)竹卡澜沧江大桥线形控制与监测

Linear Control and Monitoring of G318(Tibet Border)Zhuka Lancang River Bridge

在连续刚构桥施工中,对线形的有效控制是桥梁在不同施工温度及工况下成功合拢及平顺的保证。通过对G318(西藏境)竹卡澜沧江大桥实际施工中的线形控制及监测,探讨了该连续刚构桥梁施工过程中线形控制和监测的要点和方法,为同类桥梁工程的线形监测提供参考。

In continuous rigid-frame bridge construction, linear control work can ensure the bridge to be closed successfully and the line to be smooth in different construction temperature and different working conditions. By the linear control and monitoring of the G318 （in Tibet border） Zhuka Lancang River Bridge construction, the article discusses the points and methods of linear control and monitoring in the process of the continuous rigid-frame bridge construction, which aims at providing a reference for linear monitoring in the similar bridge construction.
