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。
It is of great significance to carry out the monitoring and forecasting of potential geological disasters on the highway to maintain the highway safety. In view of the fact that the geological hazards of highway are greatly influenced by human factors and the data of the monitoring and forecasting system involve many types of data, the data of the system are organized according to the functional requirements of the system. The data of the disaster forecasting is based on the data of each potential disaster point According to the characteristics of all kinds of entities in the base class, each base class is divided into several subclasses, and the basic entities are defined as well as the entities Relationship between the properties of the model to achieve a variety of types of data of organic organization.
