【摘要】：摘要：我国西部山区地质灾害分布广泛,类型众多,且发生频繁,极大的威胁着人民的生命和财产安全。“贵州山区高速公路边坡地理信息系统”实现了从宏观上对贵州省地质灾害易发程度区划,并结合实时雨量对危险区域进行预警预报,为路网规划、设计及运营维护提供信息参考；对公路单体边坡进行可视化管理和稳定性分析,并对危险性较大的边坡提供监测管理与预测预报功能,从而达到防灾减灾的目的。本文主要进行了以下工作： (1)在贵州省历史灾害数据和其它地理信息数据的基础上,研究地质灾害易发性评价方法,并采用地理处理工具构建基于主客观最优组合赋权的可拓学法区划模型,将模型封装并发布为基于ArcGIS Server的地理处理服务； (2)建立贵州省地质灾害易发性区划子系统,实现贵州省地质灾害易发性区划图的自动化绘制,并构建雨量模型使之能结合实时雨量信息进行地质-气象耦合预警； (3)研究边坡稳定性分析方法并构建边坡稳定性分析模型库,从确定性和不确定性两个方面对边坡进行稳定性分析和分级,并基于WebGIS技术实现对边坡的可视化管理； (4)构建监测数据预处理模型和灾害预测预报模型,实现对边坡的灾害预警预报； (5)利用富互联网应用技术和WebGIS技术,研发“贵州山区高速公路边坡地理信息系统”。
[Abstract]:Absrtact: geological disasters are widely distributed in western mountainous areas of China, and occur frequently. It is a great threat to the life and property safety of the people. "Guizhou Mountain Highway Slope Geographic Information system" realizes the division of geological hazard vulnerability in Guizhou Province from the macro perspective. Combining with the real-time rainfall to forecast the dangerous area, it provides information reference for road network planning, design, operation and maintenance. Visual management and stability analysis of single slope of highway are carried out, and monitoring, management and forecasting functions are provided for slope with high risk, so as to achieve the purpose of disaster prevention and mitigation. The main work of this paper is as follows: 1) based on the historical disaster data and other geographic information data of Guizhou Province, the evaluation method of geological hazard vulnerability is studied. Furthermore, the geographical processing tool is used to construct the extension method zoning model based on subjective and objective optimal combination weight, and the model is encapsulated and published as the geographic processing service based on ArcGIS Server. 2) establishing the subsystem of geological hazard susceptibility zoning in Guizhou province, and realizing the automatic drawing of geological hazard susceptibility zoning map in Guizhou province. The rainfall model is constructed so that it can be combined with real-time rainfall information to carry out geological and meteorological coupling early warning. 3) study the slope stability analysis method and construct the slope stability analysis model base, analyze and classify the slope stability from two aspects of certainty and uncertainty. The visual management of slope is realized based on WebGIS technology. 4) constructing the pre-processing model of monitoring data and the model of disaster prediction and forecasting to realize the early warning and forecasting of slope disaster; Using rich internet technology and WebGIS technology, this paper develops "Guizhou Mountain Highway Slope Geographic Information system".
