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 analysis of multi-source information and 4D visualization of the construction process are realized based on 3DGIS, which can provide theoretical and technical support for site control and management of the rock-fill dam.
