smoke layering meaning in English
烟层 室内或室间内在没有气流扰动的情况下
Examples
- According to the evaluations of personnel evacuation time and simulation of smoke layers development , the proposed approach indicates that temporary closure of the mid - stair can still meet the 2 . 5 minutes standard stipulated in the moe code
通过对其维修前（满足规范要求）和维修期间（不满足规范要求）两种情况下人员疏散过程的比较，并辅以烟气运动规律的预测，得出了该建筑在施工期间的安全水平。 - After analyze the foundation of the current national code ( code for fire protection design of tall buildings gb500045 - 95 ) through experiments and fire simulations , the author has found that there are some limitations on the use of this national code for the designing of smoke management system in an atrium . this paper has been discovered that it is not enough when using the smoke layer interface height as a criterion to make an assessment on the safety rate in a building fire , or to calculate the egress time
通过上述实验研究和数值模拟研究，发现当采用我国现行的《高层民用建筑防火设计规范》 （ gb50045 - 95 ）来指导中庭建筑的排烟系统设计时，在本文设计的火灾场景条件下（参照实际的中庭商场调研情况，即火灾载荷密度较大时） ，对于本文实验研究中所采用的相似模型及原型建筑，无论是采用自然排烟或者是采用机械排烟，其排烟量皆不足。 - With analyzing of the case study and based on simulating and analyzing quantitatively , this article , considering the goal of the performance - based fire - protection design is protecting occupants from being injured and keeping buildings from being damaged , thought that fire compartmentation of a large building of saling books can be divided according to their saling malls and fire compartmentation in the saling mall can be separated by the fire - proof screen . on the evacuation design , the quantity of safety exits around these buildings and the evacuation width should be increased if possible and the safety exit number , exit width and evacuation distance can be determined according to the simulating results on smoke layer temperature and height , concentration of co2 and co , occupants evacuation time and visibility . on the means of preventing and discharging smoke , the most proper measure should be determined according to their geometrical characteristics and the natural means of discharging smoke is feasible to the large building of saling books . based on analyzing of smoke
通过对案例分析研究,本文认为大型书城建筑性能化防火设计研究的最终目的是保证人员生命安全和保证建筑结构安全,在模拟计算和量化分析的基础上,大型书城的防火分区可以将中庭连通的书城区域划分为一个区,在书城场地内可以采用防火卷帘进行防火分区划分;在人员疏散设计中,应尽可能利用书城卖场的空间设计较多的安全出口和增大疏散宽度,其安全出口数量、宽度和疏散距离可以根据人员安全疏散时间和烟气温度、沉降高度、 co2浓度、 co浓度、能见度模拟计算结果验证确定;在防排烟方式的选择上,应当根据建筑物的几何特点选取最适宜的措施,就大型书城建筑而言,采用自然排烟的方式是可行的。
