With nearly 10 years of large-scale construction of Shanghai subway network, the drive of expo 2010, and also the pressing needs of space extension for urban regeneration and modernization, the exploitation of underground space in Shanghai has been greatly advanced. By the end of 2015, the total volume of underground space in Shanghai had reached 65 million square meters, and the per capita possession of the area of underground space is nearly 3.0 square meters. In the meanwhile, the safety issues during the use of underground space facilities are also increasingly prominent, not only because of the internal closure features that easily cause and spread disasters, but also the safety management and disaster prevention hardware that hide great danger. These problems have already been the important restriction factor in the comprehensive utilization of underground space resource in Shanghai. The authors and their team began to undertake the government-sponsored research projects of underground space safety issues in 2008, and by combining the literature research and empirical research during the following several years, the team made site surveys of more than 100 underground architectures in use. On the basis of this, the team used experts experience analysis and bowknot analysis methods to identify the causes and risks of the disasters and accidents, therefore refined and summed up the underground space safety evaluation index system. In order to achieve the quantitative evaluation, the team also made the evaluation criteria system according to the current law and technical standards, and used the AHP methods to build the weight system, and finally established the whole underground space safety evaluation system. The system has already been used for trial evaluation practice of several underground projects in Shanghai and provided effective basis for the improvement of the disaster control facilities and safety management of these projects.
