摘　　要：通过盐水实验,考查利用竖井实现多层建筑复合通风的可行性。介绍了基于竖井的多层建筑复合通风方案及其定量设计方法。阐述了盐水实验原理、相似率及参数选择方法,研究了建筑复合通风盐水实验的相似准则。以一个缩尺寸(1∶40)的3层建筑为研究对象,进行了3种工况盐水实验。结果表明,对于多层建筑,竖井式复合通风是一种切实可行的通风方案。Examines the feasibility of the stack-based hybrid ventilation theory by means of the salt- water model experiment. Presents a stack-based hybrid ventilation scheme for multi-story buildings and the quantitative design method. Expounds the principle of the salt-water experiment, similarity rate and the methods of parameter selection, and studies the similarity criterion of salt-water experiment. Taking a scale-down （1 ： 40） three-layer building as the experimental object, carries out the salt-water experiments under three different conditions. The results show that the stack-based hybrid ventilation is a kind of feasible scheme for multistory buildings.
