Abstract
Objective: the subsidence of soft soil subway tunnel structure is a key threat to the safe operation of subway system. In order to detect and respond the problems timely, it is necessary to constantly monitor the subsidence of soft soil subway tunnel structure and to analyze its variation over time. Methods: a subway tunnel is buried in the ground and is usually in operation all the time, making it difficult to use common methods of monitoring the deformation of the tunnel structure. This difficulty can be overcome by deploying sensors. In this study, based on the characteristics of soft soil subway tunnel subsidence, data of various influencing factors have been monitored. According to the principal component analysis and the qualitative analysis of different factors, a mathematical relationship was derived between each influencing factor and soft soil subway tunnel subsidence. By applying principal component analysis from both time and space, the degree of influence of each factor was analyzed both qualitatively and quantitatively. Results: the results accurately showed the influence of different factors in the process of subway tunnel subsidence. Conclusion: this study shows that the use of sensors could be a practical and effective method to monitor the settlement of soft soil subway tunnel.
