基于GIM的水利水电灌浆工程三维可视化分析方法与应用

水利水电灌浆工程具有“作业隐蔽、数据量大、经验性强”等特点,长期以来其质量控制成为行业面临的难题。以建筑信息模型(BIM)核心价值理念为导向,以提高灌浆分析效率与效果为目标,遵循全过程“实时监控、快速分析、动态反馈”的思路,研究了基于地质信息模型(GIM)的灌浆工程三维可视化分析方法,包括GIM模型的构建与分析方法、灌浆工程参数化与可视化技术、灌浆过程实时监控与可视化技术等,并在此基础上研发了基于GIM的灌浆工程三维可视化分析系统。工程实践表明,该方法可实现事前灌浆孔地质条件的预测预判、事中灌浆过程的实时监控与异常诊断、事后成果数据的快速分析与评价,为隐蔽灌浆工程的质量控制与管理提供了可靠技术支撑。

Three-dimensional Visualization of Grouting for Water Conservancy and Hydropower Project Based on GIM: Analysis Method and Application

The quality control of water conservancy and hydropower grouting project has been a difficulty in the industry for a long time because of its hidden operation, large amount of data and strong experience. Guided by the core values of BIM (Building Information Modeling), the three-dimensional visualization analysis method of grouting engineering based on GIM (Geological Information Modeling) is researched in this paper to improve the efficiency and effectiveness of grouting analysis following the idea of “real-time monitoring, rapid analysis and dynamic feedback” in the whole process. The analysis method includes the construction and analysis of GIM model, the parameterization and visualization of grouting engineering, the real-time monitoring and visualization of grouting process, etc. On this basis, a 3D visualization analysis system of grouting engineering based on GIM is developed. Engineering practice manifests that the present method could accomplish the prediction of geological conditions of grouting holes in advance, the real-time monitoring and abnormal diagnosis in the grouting process, and the rapid analysis and evaluation of the results after the process, hence offering reliable technical support for the quality control and management of concealed grouting project.
