随着智慧水利建设的推进，水利水电高边坡工程面临着信息反馈滞后、现场监控不足、施工质量控制不到位等状况。基于这些问题，提出了一种结合建筑信息模型（building information modeling, BIM）、有限元分析与混合现实（mixed reality, MR）的数字化解决方案。基于MicroStation软件，通过钻孔数据创建BIM模型，导入ABAQUS进行三维地应力平衡以及二维边坡降雨入渗分析，通过部署现场监测系统，结合进行二次开发，将分析结果和监测数据反馈至MicroStation中，实现了数值计算结果与BIM环境的互通；同时将BIM模型导入Unity3D平台中，并借助HoloLens2头戴式MR设备，将虚拟的三维模型、分析结果和监测数据与现实环境叠加，实现了工程现场的可视化和交互式分析。通过迈湾水利枢纽工程的案例，展示了该技术的实际应用效果，有效提升了水利水电高边坡工程的数字化管理水平和安全保障能力。这些技术的融合不仅促进了信息模型在实际工程中的优化和协同，还为工程安全性、可靠性和效率性提供了新的支持和解决方案。

With the advancement of smart water conservancy construction, high slopes in hydraulic and hydropower engineering face issues such as delayed information feedback, insufficient on-site monitoring, and inadequate construction quality control. A digital solution was proposed that integrates BIM (building information modeling), finite element analysis, and MR (mixed reality) technology to address these challenges. Using MicroStation software, a BIM model was created based on drilling data, which is then imported into ABAQUS for three-dimensional geostress balance and two-dimensional slope rainfall infiltration analysis. By deploying an on-site monitoring system and making secondary development, the analysis results and monitoring data are fed back into MicroStation, achieving interoperability between numerical calculations and the BIM environment. Furthermore, the BIM model is imported into the Unity3D platform, with the help of the HoloLens2 MR headset, virtual three-dimensional models, analysis results, and monitoring data are overlaid onto the real environment, enabling visual and interactive analysis at the engineering site. The practical application of this technology is showcased in this paper through the Maiwan Hydraulic Hub Project, demonstrating its effectiveness in raising the digital management level and improving the safety assurance capabilities of high slopes in hydraulic and hydropower engineering. The integration of these technologies not only optimizes and collaborates information models in actual projects but also provides new support and solutions for the safety, reliability, and efficiency of engineering.
