Small-scale　model　experiments　were　conducted　to　examine　the　effectiveness　of　a　point　smoke　exhaust　system　in　an　asymmetrical　V-shaped　tunnel.　Using　a　design　fire　power　of　20　MW　as　a　reference,　the　study　explored　the　optimal　smoke　exhaust　rate　for　the　point　exhaust　system　in　tunnels.　Additionally,　the　impact　of　different　slope　combinations　and　various　smoke　vent　opening　configurations　on　the　smoke　control　efficiency　was　analyzed　when　the　fire　source　was　positioned　at　the　slope　transition　point　of　the　V-shaped　tunnel.　The　results　indicate　that　an　exhaust　rate　of　approximately　140-160　m3/s　is　effective　in　controlling　smoke　for　a　20　MW　fire.　In　V-shaped　tunnels,　when　three　exhaust　vents　are　symmetrically　opened　on　both　sides　of　the　fire　source,　smoke　diffusion　on　the　large　slope　side　remains　uncontrolled.　To　address　this　issue,　increasing　the　number　of　smoke　exhaust　vents　on　the　large　slope　side　can　enhance　smoke　control.　However,　when　the　slope　difference　between　the　two　sides　of　an　asymmetrical　V-shaped　tunnel　is　excessively　large-especially　when　the　large　side　has　a　very　high　inclination-effective　smoke　control　becomes　significantly　more　challenging.
