Construction sites pose dangers in a high-intensity earthquake environment. The traditional AHP algorithm is often used to analyze the risk of construction sites but provides poor analysis results because it ignores earthquake resistance. Therefore, a risk modeling method for construction sites under high-intensity earthquakes is proposed. First, the TOPSIS method is used to obtain the indexes of earthquake risk assessment, and the matter element analysis model of risk assessment index is constructed. The comprehensive weight of the seismic risk assessment index is obtained on the basis of the combination weighting of the AHP-entropy weight method. Then, the Bayesian network is used to deduce the risk parameters of construction sites under high-intensity earthquakes. A risk assessment model of construction sites is constructed by using the dividing standard and the calculating method of earthquake magnitude in accordance with the risk evaluation criteria and acceptance principle of building construction sites. The model can be used to complete the modeling analysis of the risk of construction sites under high-intensity earthquakes. Experimental results show that the designed model can accurately analyze the hazards of construction sites under high-intensity earthquakes and ensure the safety of the whole construction site. Therefore, the model has important application values.
