基于GIS公路地质灾害信息管理系统的设计与实现

Design and Implementation of Highway Geological Hazards Information Management System Based on GIS

根据公路地质灾害发生的特点及传统管理的缺点,提出了基于GIS公路地质灾害信息管理系统的必要性。结合西部在建、运营中的高等级公路中的某些重点地质病害路段的工程实际情况,依托商用GIS系统强大的空间分析能力和图像功能,以Oracle为系统数据库、ArcGIS为地理信息系统工具的开发平台,采取集成二次开发的方式用跨平台语言Java进行整个系统的研发工作。该系统以地质灾害的空间图形信息和属性信息为基础建立系统数据库,依托数学评价、预测和预报模型以及GIS系统的空间分析能力,形象地评价、预测和预报了地质灾害,为西部公路建设管理部门有效控制和防治地质灾害、降低地质灾害造成的损失提供科学决策依据。

Based on the characteristics of highway geological hazards and the of information management,the paper puts forwards the necessarity of highway geological hazards information management system based on GIS. Combined with actual geological hazards of the eatablishing and established high- way, supported with the great dimensional analysis and image processing function of commercial GIS, the system is developed integrated secondly with the languge Java based on the oracle dabatase and ArcGIS. The system builds the database of road geological hazard on the grounds of spatial graphic information and at-tribute information. By virtue of the scientific assessment and prediction mathematical model, integrating the GIS＇ s strongpoint on spatial analyzing, the system is capable of visualizing the regionalization of road according to the geological hazards it contains, and of assessing and predicting geological hazards accurately, thus it helps the road construction and management units efficiently to control the geological hazards and reduce the related loss.
