Abstract
The visual guidance system aims to convey the environmental information through selecting, handling and integrating the carrier of visual information. Because of the characteristics of underground space itself, its interior defence against calamities is rather complicated. Therefore, hazard prevention has increasingly become the significant project to develop and utilize the underground space in a scientific, reasonable, safe and effective way. From the angle of safety, this paper elaborates the necessity of visual guidance system to prevent and cure the interior underground space, discusses and brings forward the structural strategy based on the safe guidance system of underground space. Besides, it also brings forward the suggestion to enhance the security of interior underground space by making use of the guidance system of underground space in order to improve the special characteristics to prevent and reduce the disasters in it and increase the elasticity of the cities to endure disasters.
