摘　　要：大型地下洞室群的施工通风问题是保证安全、加快施工进度的关键。传统的施工通风设计无法掌控真实通风效果,导致资源浪费。基于流体力学理论的地下洞室群施工通风三维数值模拟,能定量分析大型洞室、关键节点或通风洞(井)等的通风效果,为通风方案的设计和优化提供依据。The construction ventilation problem of large underground tunnel-chamber groups is the key to ensuring security and speeding up the construction progress.The traditional construction ventilation design can not control the real ventilation effect,resulting in the waste of resources.Based on fluid mechanical theories,3D numerical simulation on the construction ventilation of underground tunnel-chamber groups can quantitatively analyze the ventilation effect of large tunnel-chambers,key nodes or ventilation holes（wells）,etc,and provide a basis for ventilation design and optimization.Engineering applications show that the method is feasible,reasonable and scientific.
