【摘要】：为克服单一风险评价方法过于主观或客观的缺点,文章首先基于博弈组合赋权法建立了桥梁工程风险评价模型,从自然风险、人为风险、技术和结构退化等风险来源方面建立了风险指标评价体系,对各层风险因素分别基于AHP、熵理论进行主、客观权重求解,兼顾专家的主观意项和工程固有的客观信息,基于博弈原理对风险指标的权重进行组合赋权;最后基于模糊数学法和最大隶属度原理进行了工程风险等级评估。以某桥为例,验证了模型的科学性。
[Abstract]:In order to overcome the disadvantages of the single risk evaluation method which is too subjective or objective, this paper first establishes a bridge engineering risk evaluation model based on the game combination weighting method, which is based on natural risk and artificial risk. Based on AHP and entropy theory, the risk index evaluation system is established in terms of technical and structural degradation and other risk sources. The subjective and objective weights of each risk factor are calculated, taking into account the subjective meaning of the expert and the inherent objective information of the project. Based on the game theory, the weight of the risk index is weighted, and the engineering risk grade is evaluated based on the fuzzy mathematics method and the principle of maximum membership degree. Taking a bridge as an example, the model is verified to be scientific.
