In this paper, the reliability evaluation of construction waste landfill construction projects under the development of zero-emission cities is studied. Firstly, through literature review and field research, a reliability evaluation index system for construction waste landfill projects applicable to the study area was established. Then, through the empirical analysis of construction waste landfill projects in the study area, the feasibility and validity of the index system were verified. Finally, the research results are summarized and analyzed, and suggestions are made to further improve and expand the reliability evaluation index system of construction waste landfill construction projects.
