With urbanization and the rapid development of social economy, China’s rail transit industry has developed rapidly in recent years. In order to alleviate pressure road network, subways provide convenience as they are fast space-saving. Subway stations major energy consumers urban power grid due their large traffic volume long operation time. On premise ensuring safety, reducing consumption subw...

The existing Beijing Pingguoyuan Subway Station was extended through a extension project. excavation for the located directly above station. Complex interactions exist between structure and retaining pile wall of excavation. Based on this project, three-dimensional finite element models were established to investigate mechanical characteristics embedded non-embedded walls. A parametric analysis...

−Several data-driven prediction methods based on multiple linear regression (MLR), neural network (NN), and recurrent neural network (RNN) for the indoor air quality in a subway station are developed and compared. The RNN model can predict the air pollutant concentrations at a platform of a subway station by adding the previous temporal information of the pollutants on yesterday to the model. T...

The Platform Screen Doors improve Indoor Air Quality (IAQ) in the subway station; however, and the air quality is degraded in the subway tunnel. CO2 concentration and indoor particulate matter value are high in the tunnel. The IAQ level in subway tunnel degrades by increasing the train movements. Air-curtain installation reduces dusts, particles and moving toxic smokes and permits traffic by ge...

With the development of underground transportation, in order to reduce impact on surrounding environment and traffic, Hejiaying subway island station adopts concealed excavation method. During construction process, considering method, tunnel layout, ventilation requirements, working face as a multi-conductor cave, more stringent requirements are put forward for tunnel. Through combination theor...
