We introduce AudioMetro, application software for blind users that represents a subway system in a desktop computer to assist mobilization and orientation in a subway network. A user can organize and prepare a travel by using the software before riding the subway. Conclusions of the usability study revealed the critical importance of using key interface elements, such as audio-based hierarchy m...

This paper takes the project of Hejiaying Station Xi'an Subway Line 2 as background for study. The dynamic numerical simulation construction process station by PBA method is carried out using 3D finite element method. changes surface settlement, vault headroom convergence and structural stresses are studied up to intersection guide tunnel large section duct. research results show that: upper ho...
