Abstract: In recent years, the frequent occurrence of safety accidents in construction projects has brought a lot of adverse effects to the enterprise and the community. In the event of unexpected incidents, how to choose the best contingency plan and how to carry on the scientific appraisal to the project emergency management have been a key research focus. Based on this, the characteristics and emergency management of large-scale construction projects were studied, and the theory of interval valued intuitionistic fuzzy sets and interval numbers were studied in detail. According to the project criteria with incomplete uncertain information on weights of emergency decision problems, the emergency management model of construction project based on interval valued intuitionistic fuzzy information was put forward, which can effectively solve the fuzzy project and uncertainty in emergency management. Taking the collapse of a certain project as an example, the concrete steps of emergency management decision-making evaluation were studied. It is proven that the research on emergency management evaluation of large scale construction projects based on interval intuitionistic fuzzy information is beneficial to ensure the scientific and rationality of emergency management, and it can effectively reduce the damage caused by unexpected events.

Key words: interval number, intuitionistic fuzzy set, engineering project, emergency management
