摘　　要：以沪蓉西高速公路宜昌—恩施段渔泉溪大桥的施工控制为背景,通过对大桥进行施工仿真分析,模拟其施工过程,运用Kalman滤波法误差理论对大桥的施工进行误差分析调整,通过现场的标高测量和控制断面应力数据,进行桥梁结构线形和受力状态分析,并指导施工。In this paper, the background is set in the construction control of Yuquanxi Bridge in Yichang- Enshi Segment of Shanghai-Chengdu-Xizang Expressway. The following procedures are taken： the simulation analysis of the bridge construction, simulation of the construction process, adjusting of the error analysis of the construction of the bridge using the error theory of Kalman filter method. Through on-site elevation measurement and control of the section stress, bridge linear structure and the load condition is analyzed and guidance provided to the construction.
