流溪河特大桥施工监控

以流溪河特大桥为工程背景，介绍了桥梁施工监控的内容及其目的，并通过有限元软件建立该桥有限元仿真模型，计算桥梁结构理想状态，采用根据实测结果进行参数识别修正模型参数的方法，较好的预测施工阶段的立模标高，最终确保了合拢精度，使成桥后的结构线形和内力满足设计要求。

Construction Monitoring and Control of Liuxihe Bridge

Based on liuxihe long-span brige, the main content and its purpose of construction monitoring and control was introduced first, then bridge finite element simulation model was built through the finite element software and calculating, according to test results, parameter identification was also done on the bridge, and then forecasting construction stage of vertical mold elevation, finally ensure the accuracy, make the linear and internal force meet the design requirements after the structure of the bridge was folded.
