| 摘 要： | 为有效控制公路桥梁施工安全风险,提出一种可量化的公路桥梁施工安全风险评估方法。先构建我国公路桥梁施工总体安全风险评估指标体系,并基于蒙特卡洛抽样技术,运用k-s法对该评估指标体系总体分布进行有效检验。在此基础上,在给定的置信区间下对总体安全风险等级阈值进行界定划分,并通过实例进行验证。研究结果表明:该评估方法具有方便、实用、可靠性强的特点。 |

| Abstract: | In order to effectively control safety risk in highway bridge construction,a kind of quantification risk evaluation method of overall safety in highway bridge construction is proposed.Firstly,the index system of risk evaluation of overall safety in highway bridge construction is constructed.Secondly,the overall distribution of the index system is effectively tested by k-s method based on Monte-Carlo sampling technique.On this basis,the threshold value of risk grade of safety risk is defined and classified under the given confidence interval,and the results are verified by a practical example.The results show that the practicability and the reliability of this risk evaluation method are excellent. |
| Keywords: | risk evaluation index system Monte-Carlo sampling risk grade threshold value |
