摘　　要：由于公路发生地质灾害可能会造成重大损失,因此对公路沿线的可能成灾点通常会进行监测并采取其他防护措施。同时,公路成灾与其施工密切相关,因此,公路地质灾害预报比一般山地地质灾害预报涉及的信息量更多,更复杂。提出了从面到线、从线到点的公路地质灾害多层次综合预报方法,构建了方法概念模型、系统功能关系模型、数据模型及实现模型,从概念层、功能层、数据层及实现层建立了较为完整的公路地质灾害面线点多层次综合预报体系结构。该体系结构已应用于西部公路地质灾害监测预报系统取得较好的效果。Highway geological disasters may lead to great damages. So usually points with potential geohazard along the highway are monitored, and at the same time some protective measures are taken. Also, the occurrence of geo- logical disasters is closely related to highway construction, therefore, highway geological disaster forecast involve more information and is more complicated than general mountainous geological disaster forecast. This paper thus proposed the multi-hierarchy integrated prediction method of highway geological disasters from surfaces to lines, and from lines to points, to construct the methodlogy concept model, system function relation model, data model and implementation model, and established a more complete integrated prediction system structure of surface-line-point multi-hierarchy in highway geological disasters from conceptual level, functional level, data layer and implementa- tion level. It has been applied to the highway geological disaster monitoring and forecasting system in western China and has already had good effects.
