Research on Active Disaster Prevention of Underground Space Based on City Vulnerability Analysis

Abstract:

The paper deals with active disaster prevention of underground space by analysis of city vulnerability. City vulnerability includes structural and risk-based vulnerability. City structural vulnerability is mainly decided by the level of exposure and the degree of sensitivity of city to unexpected events. City risk-based vulnerability is mainly decided by the tolerance of city to risk and the probability of risk. As one of underused resources currently, underground space has the functions of reducing exposure of facilities, lowering sensitivity to disasters and improving tolerance to risks. Developing underground space is an important way to reduce city vulnerability effectively. Active disaster prevention of underground space is defined that underground space is an important and necessary part of city comprehensive disaster prevention system. Point, linear and surface underground space combines with ground disaster prevention space to form city three-dimensional disaster prevention space. We should integrate city space from the three-dimensional perspective and promote the construction of “reducing city vulnerability” in order for city harmonious development. The integration of city disaster prevention space includes three levels of integration in idea, function and entity.
