Fire in the underground space is a serious accident. It's very essential to study the evacuation technology and how to rescue people in the fire situation. There are about 4 kinds of evacuation style in long and bit tunnel after a fire, that is. The authors do the research about the fire evacuation technology based on risk theory. In the article, 5 grades fire risk grades have been made. that is:1 fire risk grade is can be ignored, 2 is should attention, 3 is serious, 4 is very serious and 5 is disaster. Then the authors designed the optimization tunnel escape structure based 2 grade fire by CFD technology to simulate the fire situation and to design the distances between evacuation connect tunnels. The conclusion is: when the fire velocity is 3.0m/s, and the distance between connect tunnels is below 100m, the evacuation is successful. Finally, the author states that the evacuation designed in the article can be accepted by society, however, should be consideration yet.
