Study on Construction Monitoring of Long Span Skew Curved Continuous Box Girder Bridge

摘要: 本文以某大跨径预应力混凝土斜弯连续箱梁桥为背景，建立空间有限元模型。通过结构仿真分析和现场实测数据对主桥线形进行监控，论述了大跨径斜弯连续箱梁桥施工监控关键技术，其结果对类似桥型施工监控具有一定的借鉴意义。

Abstract: In this paper, a space finite element model is established on the background of a large span pre-stressed concrete skew curved continuous box girder bridge. Through the structural simulation analysis and field measurement data, the main bridge alignment is monitored. The importance of construction monitoring of long-span skew curved continuous box girder bridge in bridge construction is discussed, and the results are of some reference significance for similar bridge type construction monitoring.
