Problems solved by technology

[0017] At present, the ventilation simulation test models of highway tunnels in China are generally small (1:100~1:35, a small amount of 1:20), short in length (within 30m), and the data acquisition method is not advanced (reading the height difference of the water column), and the simulated state dynamics poor similarity

Description

technical field [0001] The invention relates to a tunnel ventilation experiment model, in particular to a double-hole complementary network ventilation experiment model applied to highway tunnels. Background technique [0002] Ventilation systems are an important part of road tunnels. For extra-long highway tunnels, the quality of the ventilation system scheme is directly related to the function and benefit of the highway tunnel, which is very important. At present, the ventilation schemes of long highway tunnels at home and abroad include longitudinal ventilation, segmented longitudinal ventilation, transverse and semi-horizontal ventilation, and network ventilation. Among them, the design and research of longitudinal ventilation, segmental longitudinal ventilation, transverse and semi-horizontal ventilation are currently relatively mature, and the ventilation theory has been relatively perfect. However, domestic and foreign studies on the ventilation scheme of highway tu...
