摘　　要：基于广东某高速公路258处高路堑边坡地质灾害数据样本,总结了该高速公路边坡地质灾害类型,提出一种多灾种分阶段全过程的高速公路边坡安全风险评估方法并进行应用。采用神经网络方法(GABP)与层次分析方法(AHP)相结合建模,对该高速公路路堑边坡进行安全风险评估。结果表明,该高速公路路堑边坡主要灾害类型为冲刷剥落、溜坍坍塌与滑坡;基于遗传算法优化的BP神经网络完成了该高速公路路堑边坡安全风险的易发性评估;基于层次分析法,得到该高速公路路堑边坡多灾种危险性、危害性评估模型;该高速公路258处高路堑边坡总体情况良好,高风险边坡为0处,溜坍坍塌较高风险边坡占比为0.37%。Based on geological disaster data samples from 258 high cutting slopes on the a certain expressway in Guangdong province,this paper summarized the types of geological disaster on the expressway slopes,and proposed a multi-disaster phased full-process expressway slope safety risk assessment method,which was then applied.A combination of neural network method(GABP)and analytic hierarchy process(AHP)was used to model the safety risk assessment of the expressway cutting slope.The results indicated that the main types of geological disasters on the cutting slopes of this expressway are erosion,spalling,sliding,collapse,and landslides.The BP neural network optimized by genetic algorithm has conducted the vulnerability assessment of the safety risk of the cutting slope of this expressway.Based on the Analytic Hierarchy Process,a multi-disaster risk and disaster assessment model for the cutting slope in this expressway had been obtained.The condition of 258 high cutting slopes in this expressway are generally good,with a proportion of 0 high-risk slopes and 0.37%slope with a high risk of landslide and collapse.
