| 摘 要： | 随着公路建设的快速发展,我国山区公路边坡数量不断增多,分布也越来越广.针对公路边坡安全中存在的不确定性因素,建立基于集对分析理论的边坡安全综合评价数学模型.以重庆市巫山至巫溪公路k88+680、k90+380两个典型边坡为应用实例,建立由6大因素共25个指标组成的边坡安全评价指标体系,通过单指标联系度、综合联系度和相对隶属度等的计算,利用级别特征值和置信度准则等评判方法对边坡进行安全等级评价.评价结果显示巫山至巫溪k90+380边坡为基本安全等级,k88+680边坡为欠安全等级,边坡开挖后需要依据两个边坡不同的安全等级情况采取相应防护措施.

| Abstract: | In China,the number of slopes along highways in mountainous areas is very great and they are widely distributed.Taking into consideration the uncertainties in highway slope safety evaluation,a mathematic model is established for evaluating the safety of highway slopes in mountainous areas based on set pair analysis.The slopes at k88+680 and k90+380 of the Wushan-Wuxi Highway in Chongqing are taken as typical examples and their safety is evaluated with the single index connection degree,integrative connectio... |
