摘要
提出深埋地铁的新站型,进行紧急疏散演算,探讨针对深埋地铁新站型的人员消防疏散的计算问题,通过计算来验证和归纳深埋地铁站在建筑设计时应重视的设计要点,为未来深埋地铁车站的设计提供参考。将两座车站的客流代入两个深埋车站的新站型中,根据国家标准和新地标的疏散公式进行计算。结果表明:首先,新站型的建筑形式是成立的,可以满足国家标准疏散的要求;其次,两个计算公式均反映了客流与疏散设施的匹配度问题,当客流较大时,需增加通行设施的数量以及缩短站厅层至站台层的距离来满足疏散要求;再次,通过北京新地标的公式计算发现,在两种站型通行设施数量相同的情况下,影响深埋车站人员疏散时间的两大因素是站厅至站台的距离和客流。
The new station type of deep buried underground was put forward.The calculation of emergency evacuation was carried out,through which the main points which should be paid attention to in deep buried underground architectural design in subway station was verified and concluded.According to the national standard and the new landmark of evacuation formula to calculate,the two station passenger flow was put into two types of new buried deep station＇s formula.The results showed that：first,the new stations of architectural form are acceptable,which can meet the requirements of national standards for evacuation; secondly,two formulas reflect the compatibility problem of passenger flow and the evacuation facilities.When the passenger flow is bigger,the number of traffic facilities should be increased,and the distance of station hall layer to the platform should be shortened to meet the requirements of evacuation; thirdly,through the new landmark of Beijing formula,under the same conditions of traffic facilities,it is found that what affects deep station evacuation time lies in two factors：distance between standing hall and passenger flow on platform.
