Particulate matter pollution in the subway station's atmosphere can seriously influence air quality and impacts on health of workers commuters. In this study, PM2.5 samples were collected from different locations within a station Beijing, individual particles analyzed for morphology composition by Transmission Electron Microscopy with Energy Dispersive X-ray Spectrometry (TEM-EDX). The results ...

washers, fans and other devices may be required. This kind of setup is typically a requisite for the warm air in the summer to create a comfortable environment for the passengers. The last type of ventilation is in the case of an emergency, like the times the train is caught in fire. This kind of situation requires larger amounts of ventilation, which needs to be provided by mechanical means. F...

This paper presents a stochastic model for emergency evacuation simulation such as for a subway station. The model, MCEVAC was developed using Monte Carlo and a macro-simulation technique; the model includes a number of random variables, such as occupant load, initial occupant load, and pre-evacuation time. A random event of a train fire including fire location, fire growth rate, and the effect...

Based on the Yishan Metro Station Project of Shanghai Metro Line number 9, a centrifugal model test was conducted to investigate the behavior of stratified settlement and rebound (SSR) of Shanghai soft clay caused by dewatering in deep subway station pit. The soil model was composed of three layers, and the dewatering process was simulated by self-invention of decompressing devise. The results ...
