Abstract
In the deformation monitoring of the steel-shell concrete immersed tunnel construction in the Shenzhen-Zhongshan Link,the experimental research on deformation monitoring with three-dimensional aerial traverse method was carried out.Through theoretical precision analysis,simulation test,and engineering verification,the three-dimensional aerial traverse method meets the accuracy requirements of immersed tunnel construction monitoring.Compared with the conventional leveling method,it has the advantages of simple operation,saving manpower and material resources,shortening monitoring time,significantly improving the working efficiency of construction monitoring,and can provide a reference for the construction deformation monitoring of similar projects.
