摘　　要：为有效预防铁路隧道工程施工过程中的岩溶突水灾害风险,提出一种基于二维云模型的岩溶突水灾害风险等级评价体系。考虑岩溶突水灾害各风险因素的发生概率及发生后所造成的损失这2个方面,通过二维云模型实现定性概念和定量数值之间的转换,并运用熵权法确定评价指标权重,利用数学贴近度的方法将最终得到的综合风险云与各风险等级标准云进行比较,从而得出岩溶突水灾害的风险等级。在实际案例应用中,评价结果与实际情况具有良好的吻合性,验证了所设计的评价指标及方法的合理性。In order to effectively prevent Karst water inrush disaster risk during construction of railway tunnel,a Karst water inrush disaster risk level evaluation system based on two-dimensional cloud model is proposed.Starting from the probability of occurrence of each risk factor of Karst water inrush disaster and the loss caused after occurrence,the transformation between qualitative concept and quantitative value is realized through the two-dimensional cloud model,and the weights of evaluation indexes are determined by entropy weight method.Finally,the obtained comprehensive risk cloud is compared with the standard cloud of each risk level by using the method of mathematical proximity degree to get the risk level of Karst water inrush disaster.In the actual case application,the evaluation results are in good agreement with the actual situation,verifying the scientific rationality of the designed evaluation indicators and method.
