摘要
进行公路潜在的地质灾害点监测预报对维护公路安全具有重要的意义。针对公路地质灾害受人为因素影响大,监测预报系统涉及数据面与类型多的特点,根据系统功能要求研究了以面向对象的方法组织系统数据,灾害预报的实质是对潜在灾害点所表现的各类信息进行综合评估,将预报所涉及的各类实体分为6个基类,依据基类内各类实体特点将各基类划分成几个子类,构建了基类实体之间的以及实体与属性之间关系模型,实现了各种类型数据的有机组织。
The monitoring and forecasting of highway' s potential geological disasters are of great significance to maintain highways' safety. Aiming at the characteristics of highway's geological disasters' forecast, such as human' s great influence on geological disasters, various data aspects and types involved in the monitoring and prediction system, etc. , object -oriented data organization method was proposed according to system function requirements. The essence of disasters forecast is to make comprehensive evaluation for all kinds of geological disasters' information. With this in mind, all kinds of entities involved in the forecast were divided into 6 base classes, and each base class was divided into subclasses according to the base entity' s features. Then relationship models were constructed between entities, and entities and their attributes, and thus, various types of data were organized organically.
