Abstract:There are significant uncertainties in the construction risks of seashore bridges because of the complex environment and construction conditions. With the consideration of the subjectivity and the correlation between different risk factors in the risk assessment process, a fuzzy analytic hierarchy with stochastic process is proposed. Based on the stochastic process theory risk assessment method, the cross-correlation log-normal distribution stochastic process of risk factor parameters is established, and the polarization determination evaluation level of the fuzzy analytic hierarchy process is transformed into a more reasonable probability risk analysis. Taking Senegal’s Foundiougne Bridge project as a case study, the results show that: the risk assessment model based on fuzzy analytic hierarchy and stochastic process theory can accurately reflect the statistical characteristics of factor parameters and the cross-correlation between different factors; The probability that the construction lower risk level is 35.9%, and the probability of medium risk is 33.7%.
