摘　　要：鉴于以往边坡施工期安全信息管理及可视化分析方面的研究中还存在工程模型及信息动态属性描述不够、安全信息表达不全面等问题,通过引入4D技术和安全信息模型,提出水电站边坡施工期4D安全信息模型的建立方法和实现过程,重点研究了边坡信息几何载体模型的建立、安全信息的数据库存储与可视化显示以及进度—模型/信息动态映射算法等关键技术,最后应用C#.NET+OpenGL开发出边坡施工期安全信息动态可视化管理系统。以某水电站左岸边坡工程为例,实现该边坡施工面貌和结构安全状态的动态耦合可视化展示以及安全信息随施工进度的实时更新,直观地揭示了边坡安全状况随施工过程的演化规律,以满足工程人员对边坡施工期安全信息直观表达和实时动态可视化分析的需求。As there are still some problems in previous study on safety information management and visual analysis of slope engineering such as inadequate description of dynamic properties of 3D model,and incomplete expression of safety information.This paper the proposed establishment method of 4D safety information model of slope during construction in hydropower station by introducing 4D technique and safety information model. Key techniques such as establishment of information carrier model,database storage and visualization of safety information,and construction-model /information dynamic mapping method are mainly researched,finally dynamic visualization management system of slope safety information during construction is developed with C#. NET and OpenGL. Taking the slope of a hydropower station for example,coupled visualization of the figure in different construction stages and structure safety condition is displayed,real-time update of safety information with construction progress is realized,and evolution law of slope safety during construction is revealed visually. These may meet engineers＇ demand for visual expression and real-time dynamic visual analysis of slope safety information during construction period.
