竖井型城市隧道自然通风哮喘效应模型研究

摘要

在前期竖井型城市隧道自然通风模型实验研究的基础上,通过改变实验模型,研究了竖井＂哮喘效应＂产生的原因,以及如何克服＂哮喘效应＂的办法,得出＂哮喘效应＂是连续竖井通风的必然产物,是不能阻止的结论。%On the basis of model experimental study on city tunnel natural ventilation with vertical well,by changing the experimental model to study the causes of well's "asthma effect",and the approach that how to overcome "asthma effect".Concluded that "asthma effect" is the inevitable product of continuous ventilation shaft,and can not be stopped.
