水利工程BIM+GIS与施工进度动态计划关联方法及实现

在水利工程的建设管理中，施工进度会不可避免地受到外界因素的影响，导致工程施工不能按照原有计划进行。针对于此提出了基于BIM+GIS的施工进度动态计划关联方法，以互联网技术为基础，结合数据库技术和可视化技术，实现工程量统计与施工进度的动态模拟，通过Cesium 3D GIS平台建立了基于BIM+GIS的水利工程施工进度管理系统。此系统将GIS大场景与BIM深度结合，为水利工程项目参建方提供施工三维动态可视化环境，精细化控制水利工程的工程量统计与进度计划管理。目前该系统已经在某水闸工程中投入使用，应用效果良好。

Implementation method and realization of BIM+GIS in construction progress dynamic scheduling of water conservancy projects

In the construction management of water conservancy projects, the construction progress is inevitably affected by external factors, influencing the construction progress. In order to improve the situation, we proposed an implementation method of BIM+GIS (building information modeling, geographic information system) in the dynamic planning of construction progress. With this method, the dynamic simulation of quantity statistics and construction progress can be conducted using database and visualization technology based on internet technology. Therefore, a construction management system for water conservancy projects based on BIM + GIS was established using Cesium 3D GIS platform. This system combines the GIS large scenes with the BIM depth to provide a three-dimensional dynamic visualization environment for the water conservancy project construction participants. Meanwhile it can finely control the engineering quantity statistics and schedule management of the water conservancy project. At present, the system has been put into use in a sluice project, and the application effect is satisfactory.
