Solutions for Extracting Air and Smoke in Underground Subway Station
Applied Mechanics and Materials, 2014Everyday there are about 7 million passengers commuting by subway in Shanghai, China. Although Shanghai has one of the largest subway networks in the world, yet this subway system is still full of passengers during the rush hours. Extracting air and smoke is important part of the station ventilation system which supplies enough fresh air in the crowded

Science of The Total Environment, 2023
Due to the rapidly increasing ridership and the relatively enclosed underground space, the indoor air quality (IAQ) in underground subway stations (USSs) has attracted more public attention. The air pollutants in USSs, such as particulate matter (PM), CO2 and volatile organic compounds (VOCs), are hazardous to the health of passengers and staves ...

Underground air quality monitoring in subway stations in Bucharest city
AIP Conference Proceedings, 2020As a result of the urban development in the cities, the underground transport has become a priority transit route used by the population, due to the fact that it is a faster route and also due to the need to reduce the road traffic from the surface in order to improve the quality of the air (especially degraded from traffic emissions).

Commuter exposure to particulate matter at underground subway stations in Philadelphia
Building and Environment, 2020Abstract We present the first report of exposure to particulate matter by commuters at 12 underground subway stations in Philadelphia, Pennsylvania, USA. Particle measurements were taken during two springtime periods: March 4 to 9, 2018 and February 1 to April 12, 2019. Particle concentrations were variable across the subway stations and demonstrated

Crisis and Emergency Management: Theory and Praxis, 2018
Underground public pedestrian facilities were mainly built throughout the 1970s to 1980s. These facilities have been used as an evacuation area in case of emergency and a convenient access road to underground level. Underground shopping arcades were installed to reduce the construction costs and create more available space. However, during this process,

BIM Technology Used in Underground Subway Station Planning Simulation
Applied Mechanics and Materials, 2014This paper studied the underground subway station planning depend on BIM technology. The existing 3D buildings’ information was processed by computer technology. Using the information and planning based on constraints on the space station, the simulation of the actual situation in 3D view way constantly, adjust planning position, compare each project ...

Acoustical design for public address announcements in an underground subway station
Noise Control Engineering Journal, 2014The public address (PA) is a part of the passenger information system in an underground subway station. A sample station named Xingzhong Road on metro line 9 in Shanghai is considered in this paper. A ray-tracing model for acoustical simulation of the PA system is established.

Seismic performance and effective isolation of a large multilayered underground subway station
Soil Dynamics and Earthquake Engineering, 2021Abstract In this paper, the seismic performance of a reinforced concrete (RC)-framed underground subway station structure which has three stories and three spans was analyzed firstly under strong earthquakes. It was found that the central columns in the top and the bottom stories were the weakest seismic components in this type of underground ...

Shaking table test on seismic responses of asymmetrical underground subway stations
International Journal of Physical Modelling in GeotechnicsCurrently, many subway stations are designed symmetrically and less attention has been paid to asymmetrical stations. The middle column of the asymmetric underground structure is offset to one side, which is not conducive to load bearing during strong earthquakes and is prone to damage.
