Safety Risk Assessment of Prefabricated Building Construction Based on Bayesian Network

Abstract

A safety risk assessment index system including four types of risk conditions: foundation pit construction risk status, construction and shipment risk status, hoisting operation risk status and prefabricated component installation risk status is established. Based on Bayesian network, fabricated by Netica software to evaluate the construction safety risk probability, through the function of Sensitivity to Findings conduct sensitivity analysis on the probability of risk occurrence. Based on the risk calculation, get the more prominent risk factors in each type of risk situation. According to the result of risk assessment, the countermeasures of construction safety risk of prefabricated building are put forward.
