为实现质量、进度、成本等多源施工信息动态可视化集成、满足堆石坝施工全过程直观动态分析的需要,在分析了心墙堆石坝施工信息多源特性的基础上,提出了堆石坝4D施工信息模型(3D几何模型+时间+多源施工信息)定义、构架,研究了堆石坝4D施工信息模型的实现方法,包括心墙堆石坝三维可视化建模方法、多源施工信息集成方法、堆石坝施工过程4D可视化分析方法等。实际工程应用表明,基于3DGIS平台能实现堆石坝多源施工信息集成与交互式查询分析及施工过程4D可视化分析,可为堆石坝现场施工控制与管理提供重要理论与技术支持。

In order to realize the dynamic and visual integration of multi-source construction information, including quality, schedule, and cost, and to meet the need for visually analyzing the whole construction process of a core rock-fill dam, a 4D construction information model for a core rock-fill dam （3D geometric model＋time dimension＋ multi-source construction information ） is proposed based on analysis of the multi-source characteristics of the construction information. The established method of the 4D construction model was studied, including techniques for the establishment of a 3D model of the core rock-fill dam, the integration of the multi-source construction information, and the 4D visualization method in the construction process of the rock-fill dam. Practical engineering applications show that the integration and interactive construction process are realized based on 3DGIS, control and management of the rock-fill dam. analysis of multi-source information and 4D visualization of the which can provide theoretical and technical support for site
