A Web-Based Ground Settlement Prediction System for Subway Construction

Abstract

The development of a web-based ground settlement prediction system for subway construction is presented. The system is developed based on STEAD, and it is named STEAD-Web. STEAD is a ground settlement prediction system developed in China earlier. It is short for Subway Tunneling-induced ground-Environment-damage Assessment and control Design system. STEAD works well in predicting ground settlement. Unfortunately, it works off-line and it is not so convenient to deal with massive measured data every day. STEAD-Web is an upgraded version of STEAD, which runs in Browser/Server mode. The server automatically analyzes the monitoring data and makes a prediction by a back-analysis method using the real-time measured data. Users can access the results through web browsers from anywhere after authorization. Finally, the paper presents two case applications of the new system in Beijing subway construction.
