Abstract The geological characters of rockburst in Lujialing tunnel depending on the data summarized with geological observation during tunneling are studied，and the rockburst qualities including scale position and geological conditions are analyzed. Then the mainly control factors of the rockburst which consists of rock-form，geological structure，geo-stress and groundwater have been discussed from the viewpoint of geological engineering. Finally，the prevention methods in accordance with geological qualification in Lujialing tunnel have been presented.
