Development and Application for Dynamic Security Visualization System of Large-scale Underground Structure Group

In view of the dynamics and complexities of the construction safety for the large hydropower station underground structure group, the dynamic security visualization system of large-scale underground structure group has been developed with the Visualization Toolkit which has the powerful three-dimensional graphics capabilities. In this system, the monitoring data, the construction process information, the numerical analysis and the VTK system were combined together, and the method of dynamic coupling simulation for numerical simulation model and status of construction process was builted based on numerical simulation model of large-scale underground structure group. The information of visualization model which is displayed dynamically can be queried interactively and in real time, and it realizes the dynamic coupling visualization of construction process of underground structure group and safety status of its structure. Meanwhile, this system provides an intuitionistic and interactive visualization management and security control platform for the large hydropower station underground structure group, which has some engineering significance and applied value.
