In response to the problems of large construction volume, complex structure, strong risk coupling, lagging warning and insufficient accuracy of traditional control mode in large-scale event venues, this paper conducts research on intelligent warning model for construction safety risks. Firstly, a combination of literature analysis, on-site research, expert interviews, and case analysis was used to identify the safety risk characteristics of large-scale event venue construction. A three-level risk indicator system was constructed, consisting of "target layer criterion layer indicator layer", and the combination weights of indicators were determined using the Analytic Hierarchy Process and Entropy Weight Method; Secondly, by integrating CNN, LSTM algorithms, and attention mechanisms, a CNN-LSTM Attention intelligent warning model is constructed, which improves model performance through data preprocessing and parameter optimization; Finally, a construction project for a large-scale provincial-level event venue was selected for example verification. The results showed that the overall prediction accuracy of the model reached 94.2%, with an average response time of 8.6 seconds. It can warn potential safety hazards 1-3 hours in advance, and the closed-loop rate of warning and disposal is 100%, effectively improving the efficiency of construction safety control. The research results have achieved the transformation of construction safety risks from "post disposal" to "pre prevention", providing theoretical support and technical paradigms for intelligent control of construction safety in large-scale event venues and similar large-span public buildings.
