Abstract
Based on the fuzziness and randomness of cloud model, it is applied to the construction safety risk assessment of long-span suspension bridge in deep valley in mountainous area. According to the situation of Jiangdi River Bridge project, the cloud model evaluation method is adopted to add two indexes of wind load condition and import and export construction condition to the index system. The index weight is calculated by the maximum deviation weighting method, the comprehensive determination degree is calculated and the construction safety risk level is determined. By comparing the standard evaluation results of construction Safety Risk Assessment Guide for Highway Bridges and Tunnels (Trial) and the cloud model evaluation results, it is shown that the evaluation index system is constituted by adding corresponding special risk factors to the actual project and cloud model calculation is more reasonable and accurate than the traditional risk evaluation results.
