摘　　要：科学合理地进行道路塌陷风险评价对保障城市道路安全具有重要的现实意义。针对城市道路塌陷风险评价中存在的风险指标、评价等级等主观性、模糊性和随机性较强的问题,在道路地质雷达探测的基础上,综合考虑环境、塌陷属性、邻近设施3个方面,构建了道路塌陷风险评价指标体系。基于熵权法赋权,从风险和概率2个维度出发,提出了一种基于地质雷达探测和熵权二维云模型的城市道路塌陷风险评价方法。评估结果以云图形式输出,能直观地判定道路塌陷风险等级。将该方法应用于昆山市跃进路的道路塌陷风险评价实例,并与传统层次分析法进行了对比分析,验证了该方法的合理性和可行性,为城市道路塌陷风险评价提供了依据和参考。Scientific and reasonable risk evaluation of road collapse has important practical significance for urban road safety.Subjectivity,fuzziness,and randomness of risk indicators and evaluation levels is a pervasive problem in road collapse risk evaluation.On the basis of road geological information detected by ground penetrating radar,a risk evaluation index system for road collapse is constructed by considering the environment,collapse properties and adjacent facilities.Considering the risk and probability,an urban road collapse risk evaluation method is proposed based on ground penetrating radar detection and entropy weight twodimensional cloud model.The evaluation results are output in cloud map form,and then the level of road collapse risk can be determined intuitively.The method was applied to the risk evaluation of road collapse on Yuejin Road in Kunshan City.Its rationality and feasibility was verified by comparing with the traditional analytic hierarchy process.This paper can provide a basis and reference for urban road collapse risk evaluation.
