研究如何设计进入避灾硐室的供风管道以及回风管道的参数，对于如何利用压风系统对避灾硐室进行供氧，而又能保证避灾硐室内人员的安全性具有重要的意义。研究首先根据避灾硐室所需风量确定了避灾硐室压风管道的管径；其次，通过对人体最大承受能力的分析，确定了避灾硐室内最大的超压；然后，利用流体力学相关理论分析了合适的排风管径；最后，通过计算避灾硐室内的绝对压力核对是否能保证人员的安全性。研究结果可为避灾硐室的设计提供依据。

When designing and constructing the refuge chambers,it was quite urgent and necessary to solve how to effectively use the compressed -air self -help system to supply sufficient oxygen for people.The calculation of air supply tube diameter and air discharge tube diameter was import to protect safety for people in the refuge chambers.Firstly,According to the air quantity for the refuge chambers,the air supply tube diameter was studied.Secondly,according to the analysis of the most pressure to body,the overpressure in the refuge chambers was studied.Thirdly,base on the fluid mechanics theory,the diameter of discharge air tube was studied.Last,the absolute pressure was calculated to check if the person in refuge mchambers was safe.The results provide a more reasonable way for refuge chamber design.
