Abstract
Based on the existing monitoring data, this paper uses the matured data method to analyze, predict the long-term settlement of the subway shield tunnel, and comprehensively analyzes the long-term settlement of the subway shield tunnel in the saturated sand layer of Zhengzhou. Logical curve model, etc. is used to separately predict the long-term settlement of the Zhengzhou metro shield tunnel. Combining the prediction results to summarize the characteristics of the prediction model, a prediction model suitable for the long-term settlement of the subway shield tunnel in the sandy soil area represented by Zhengzhou is obtained, which can be used for the operation of the Zhengzhou subway tunnel. Management and similar engineering projects provide a certain reference basis.
Highlights
With the continuous promotion of urbanization in China, many problems in environment and transportation have been exposed, which seriously affect the development of cities and people's pursuit of a better life

Summary
With the continuous promotion of urbanization in China, many problems in environment and transportation have been exposed, which seriously affect the development of cities and people's pursuit of a better life. The second method (Liu et al 2014) is to obtain the development trend of settlement and deformation based on the existing measured data, and to use appropriate mathematical model to predict the development of settlement after that. Combined with the prediction results, the prediction summarize the characteristics of the prediction model, and obtain a suitable prediction model for the long-term settlement of the subway shield tunnel in the sandy soil area represented by Zhengzhou. It can provide a certain reference for the operation and management of the Zhengzhou subway tunnel and similar projects
