摘　　要：燃气的密度比空气轻,其附加压力随着楼层的增高而增大,因此,由附加压力增大而导致的超压问题是燃气设计常见的一个问题。分析了附加压力产生的原因,实测了某超高层住宅不同楼层高度的压力值,并根据理论计算,结合工程设计实际情况,阐述了应对附加压力引起的超压问题可采用的若干种调压方式,并随之分析了各种调压方式优缺点。For gas with a lighter density than air,the additional pressure increases with the increase of the floor.The problem of overpressure caused by the increase of the additional pressure is a common problem in gas design.This paper analyzes the causes of the additional pressure,and measures the pressure values on different floors of a super high-rise residential building.Based on theoretical calculations and the actual situation of engineering design,this paper expounds several pressure regulation methods that can be used to deal with the overpressure caused by additional pressure,and analyzes the advantages and disadvantages of various pressure regulation methods.
