During the construction of deep foundation pit,there are many adverse factors,the monitoring data survey results are poor,and the old risk assessment principle is difficult to solve.Therefore,based on the risk assessment principle of the fuzzy Bayesian Inter-net,the probability of risk events in the fuzzy numerical value is calculated by using the researcher evaluation principle in the fuzzy cal-culation results,and the probability of each risk event in each node of the model is calculated.The probability of various risk events in the project is calculated based on the deep foundation pit project of the railway station of Guangzhou Metro Line 11,The result shows that the overall safety level of foundation pit construction is at level II(partial safety),which verifies the applicability of this method.
