【摘要】 公路自然区划作为标准,是公路工程各类规范规程制定的基本依据,对公路建设基本阶段具有一定指导意义。地质灾害对公路工程有极其恶劣的影响,公路地质灾害分区的研究有助于查明国土范围内公路地质灾害的分布情况,制定区域公路防灾减灾对策,因此本文探讨了应用GIS进行公路地质灾害分区。本文首先建立了公路灾害区划类型体系,确立了公路地质灾害区划的研究对象,包括滑坡、泥石流、岩溶塌陷和地震,并分析了各灾种的特点和其对公路工程的危害。在此基础上进行了公路地质灾害分区影响因素分析,并提出了公路地质灾害分区指标体系,并基于GIS对相应指标进行了数据处理。其次,提出了指标属性数据评价分值转换及其归一化处理的方法,利用专家打分法进行了公路地质灾害分区指标权重的确定,进而根据归一化值、权重和指标3个核心因素建立了分区综合评价模型。最后,采用“自上而下”和“自下而上”相结合的区划方法,利用人机交互方式,进行了分区方案研究,提出了公路地质灾害危险性分区方案,并进行了分区评价说明。更多还原

【Abstract】 The highway natural regionalization takes the standard, is the basis of each kind of standard regulations and formulations of the highway engineering, and has the certain instruction significance to the highway construction’s basic steps. The geological disaster has the extremely bad influence to the highway engineering; the research on highway geological disaster regionalization is helpful to investigate distributed situations of the highway geology disaster in the national territory scope, and helpful to formulate countermeasures to prevent and reduce the region highway geological disasters,so this paper has discussed the regionalization of highway geological disasters based on GIS.First, this paper established the type system of the highway disaster regionalization, set up the research objects of highway geological regionalization, include the landslide, the mud-rock flow, the karsts caved and the earthquake, and has analyzed the various disasters characteristic and their harms to the highway engineering. Carried on the influence factor analysis of highway geological disaster division, and proposed the index system of regionalization , Then indexes were managed based on GIS.Second, took it as the basis of reference and confirmation of the final achievements of regionalization, simultaneously some parameters also became the division key indexes.Finally, has used unified division method of up-bottom and bottom-up, and man-machine interactive way, carried on the regionalization schemes’research, proposed the highway geological disaster hazards’regionalization in China, and has carried on the division appraisal explanation.更多还原
