Abstract In mountainous highway tunnel,ventilator chambers are usually needed. The structure of ventilator chamber is complex and always connected with vehicle tunnels. The span of ventilator chamber is large,but interval between chambers is litle. So the safety and stability of ventilator chambers are very important. The three dimensional fast Lagrange analysis method is adopted to make 3D stability analysis of ventilator chamber of highway tunnel and valuable results are obtained for given practical cases.
