Abstract: The coping and dissolving of the risk of social stability is very important to the implementation of the project. Based on the field investigation and literature research method, taking the process of the two site selection of "Linping water purification plant" project as an example, this paper analyzes the difficulties faced by the first site selection, the details of the second site selection plan, and the strategy to deal with the social stability risk. These strategies include organizing resident residents to inspect the current status of similar projects in China, formulate public participation programs for environmental impact assessment, and assess social stability risk sources and risk levels of projects. Based on this, the paper analyzes the risk perception of the public of the engineering risk, and revises and redivides the concepts and types of the previous engineering social stability risks. Finally, the paper analyzes and summarizes the strategies for engineering projects to deal with and solve social stability risks from the following three aspects: the social stability design of the project, the principle of maximum interest balance and the embodied participation of the public in the project.
