摘要:
基于有限体积法建立了地铁车站三维静态数值计算模型，对列车阻塞隧道时站台滑动门所受的活塞风压进行了计算研究；分别对单、双两种活塞通风条件下，不同活塞风速、阻塞比、滑动门位置对滑动门所受风压的变化规律进行了分析。结果表明，双活塞通风能够有效减弱活塞风对滑动门的风压；单活塞通风条件下，滑动门在最不利位置时，需克服的最大风压约为230 Pa。
Abstracts:
Based on the finite volume method, a three dimensional static numerical model of metro station is build to study and calculate the piston wind pressure on the platform sliding doors when a train blocks the tunnel. In single and double piston ventilation conditions, the changing laws of wind pressure related to the speed of piston wind, the block ratio and position of sliding doors are analyzed. The results show that the double piston ventilation will effectively weaken air pressure on the sliding doors. While in the condition of single piston ventilation and the worst door position, the maximum pressure on the sliding doors to overcome is about 230 Pa.
