Abstract
Wastewater pump room is used to lead wastewater out of subway sections. The wastewater pump room is the side channel of subway sections which is often constructed by freezing method. Since the freezing method construction has a certain risk of failure which leads to soil foundation collapse easily, as an alternative, subway section drainage can be achieved by installing a drainage pump inside railway track concrete roadbed. Because the built-in pumping weakened the original integrity of roadbed structure, in this paper, by establishing a finite element analysis model of the vehicle-track-tunnel, 12 indexes including dynamic response of the track structure, stability and safety of running vehicle were calculated. Results show that, while vehicle passing through the section, the build-in pumping structure meet requirements of track structure dynamic responses, vehicle running safety and stability.
