Risk Assessment on Operating Tunnels of High-Speed Railway in Perilous and Mountainous Area
The project named “the rescue system and key technology of high-speed railway in perilous mountains” primarily focuses on current railway constructions and operations in China. To state the relationship between risk events and risk factors, we classified the risk sources of operating tunnels of high-speed railway in perilous and mountainous area and established a hierarchical assessment system ...
متن کاملMulti-Camera and Structured-Light Vision System (MSVS) for Dynamic High-Accuracy 3D Measurements of Railway Tunnels
Railway tunnel 3D clearance inspection is critical to guaranteeing railway operation safety. However, it is a challenge to inspect railway tunnel 3D clearance using a vision system, because both the spatial range and field of view (FOV) of such measurements are quite large. This paper summarizes our work on dynamic railway tunnel 3D clearance inspection based on a multi-camera and structured-li...

متن کاملOn the Importance of the MIMO Channel Correlation in Underground Railway Tunnels
This paper deals with MIMO channel modeling according to the correlation level in underground railway tunnels for various antenna configurations for the transmitting and receiving arrays. MIMO channel matrices have been computed with a 3D ray-tracing based software at 2.4 GHz and 5.8 GHz in two different tunnel environments: 1) a 1-track empty tunnel with a square cross section, 2) a 1-track tu...
