The closure is an important part of the continuous rigid frame bridge during construction stage. The stress state of girders will change when the closure order adjusted. Therefore, reasonable closure scheme is crucial for whether the stress state to meet the design ideal state. In the actual construction, due to the terrain conditions, construction progress and the limitation of the final closure temperature, it need to adjust the order of the final closure scheme for long span continuous rigid frame. In this paper, we took a long-span continuous rigid frame bridge in Yunnan province as example. The closure plan changes and we do calculation and analysis for two kinds of closure scheme-first side span than middle, first middle span than side span. We got the bridge stress state and construction phase stress state. We analysed the differences between the two kinds of closure scheme. We chosen some stress weak position, those position should be monitored and in real construction should be strengthened monitoring.
