On conditions of different weight,height, shape and the property of slope surface, the tunnel portal structure’s deformation evoked by rock-fall impaction has been researched in laboratory by using a 1/30 scale similar model. The study shows that there is a simple linear relationship between the structure’s deformation , the rock weight and the rockfall height when the slope gradient is 1:0.5 and the slope surface is slippery and the multiple linear relationship between the structure’s deformation , the rock weight and the rockfall height has been obtained. Effect of the shape of the rockfall and the property of slope surface on structure’s deformation has been comparative analyzed.
