In order to provide data support for engineering construction, this paper proposes to study the construction of information platform of settlement deformation observation data. In this paper, the information platform for observation data is established based on the settlement deformation data of Zhengzhou-Jinan high-speed railway. The results show that the settlement deformation observation platform in this paper can effectively integrate the data and ensure the accuracy of the data. This paper sets an example for the future research on the construction of information platform of high-speed railway settlement.
