ABSTRACT As a symbol of urbanization, high‐rise buildings are flourishing, and the construction safety of high‐rise buildings has always been a hot topic of social concern. Based on the trajectory crossing theory, this article establishes a risk assessment index system for high‐rise building construction, selects five primary indicators and 28 secondary indicators, and studies and proposes a high‐rise building construction safety evaluation method based on the G1‐COWA‐IEWM‐CM (G1‐COWA Improved Entropy Weight Method Cloud Model) theory. The subjective weighting G1‐COWA method and objective weighting I‐EWM method are used to determine the weights of each indicator, and the comprehensive weight is determined based on the principle of minimum discriminative information. Compared with the traditional fuzzy comprehensive evaluation method, this method has more advantages in dealing with uncertainty and information fusion. Taking the construction of high‐rise residential buildings in a residential area in Qingdao as an example, a system dynamics countermeasure model was established based on the evaluation results. The research results show that the human factor index has the highest comprehensive weight, accounting for 24.6%. The expected cloud parameters of the actual cloud model are 85.7469, and the expected deviation from the excellent level of the actual cloud model is about 14%, while the expected deviation from the good level is about 16%. Therefore, the construction risk level of the building is concentrated between excellent and good, closer to excellent. The research in this article has theoretical guidance significance for high‐rise building construction management and can also provide research method references for research in the same field.
