数字孪生水利工程地质勘察平台研发与应用

Research and application of digital twin platform for geological survey in hydraulic engineering

当前水利工程地质勘察信息化程度相对滞后,作业、管理方式落后,成果可视化效果较差,数字孪生水利工程勘察平台集中于桌面端,现有引擎无法满足具有空间属性的大规模地上地下一体化地质构造模型,在Web端高质量显示和分析等应用需求。为解决以上问题,提出一种融合Cesium和Thress.js的数字孪生三维模型渲染方法,基于此研发数字孪生水利工程地质勘察平台、实现地质勘察的全面信息化。在多个项目中的使用,证明此平台可提高勘察数据采集的效率和成果的质量,提升Web端高质量加载海量三维地质模型的性能,拓宽成果共享再利用的方式,使勘察数据在水利工程规划建设中发挥更大作用。

Currently,the degree of informatization in the geological survey phase of hydraulic engineering const ruction is relat ively lagging behind,which is manifested in the following:outdated operation and management methods,poor visualization effects,software for survey based on digital twin technology concentrated on the desktop,and existing engines failing to meet the applicat ion requirements for high-quality display and analysis of large scale integrated geological structure models with spatial attributes on the Web,among other applications.In order to solve the above problems,a rendering method is introduced for const ructing digital twin scenarios using a 3D model that integrates Cesium and Three.js.Based on this method,software for geological surveys reliant on digital twin scenarios was developed,achieving comprehensive informatization of geological survey projects.The application of this sof tware in multiple projects has been proved to enhance the efficiency of survey data collection and the quality of outcomes,improve the performance of loading massive 3D geological models with high quality on the Web,expand the methods for sharing and utilizing results,and enable survey data to play a greater role in the planning and construction of hydraulic engineering projects.
