Comparison and prospect of deformation monitoring technology in engineering construction

This paper expounds the necessity of monitoring in the construction process of major projects, which are large-span or super-high projects. And the deformation is the most important index of monitoring parameters. In this paper, the principles of several deformation monitoring methods, such as dial indicator, precision level, static level, total station, GNSS and image technology, are introduced respectively. This paper compares the traditional deformation monitoring methods with the new deformation monitoring methods, and analyzes the advantages and existing problems of various deformation monitoring methods. Finally, the new requirements and new monitoring technologies for deformation monitoring were proposed in future engineering construction.
