Development of real time decision-making system for ground deformation due to shield tunneling

The general structure of real time decision-making system for ground deformation due to shield tunneling is described. The functions of different modules are analyzed. As an example, the gray model for the safety monitoring model of ground deformation is established. The safety rules are concluded to judge whether the ground deformation data are abnormal. The causes of the abnormal data are analyzed. Safety degree is introduced to synthetically evaluate the deformation. The project example shows that the monitoring data can be stored and inquired; and the monitoring data, monitoring models, synthetic evaluation are visualized in this system. With the synthetic evaluation, the system is available to shield tunneling.
