山地城市高边坡风险管理系统研究与应用

STUDY ON THE GEORISK MIS OF HIGH SLOPES AT MOUNTAINOUS REGION CITIES

山地城市高边坡所引起的岩土灾变已经成为制约其发展的一个重要因素。该文将山地城市高边坡灾害风险评价模型与GIS技术先进的图形处理和空间分析功能相结合,建立基于GIS的山地城市高边坡风险管理信息系统。系统由数据库模块、编辑模块、分析模块、查询显示模块以及WEBGIS模块五大模块构成。系统在对相关信息进行采集、存贮、检索和管理的基础上,实现区域岩土高边坡危险性、易损性评价,并得到高边坡风险性分析结果。

The occurrence of Geotechnical catastrophe caused by high slope has haltered the economic development of mountain cities.A risk management information system based on the GIS is established by integrating the high slope risk evaluation model of mountainous cities with the graphic processing and the spatial analysis function of the GIS.The system is composed of database module,editing module,analyses module,query and display module as well as webgis module.On the basis of collection,storing,searching,and management for the relevant information,the system can perform the regional assessment and vulnerability assessment of geotechnical high slope risk.
