摘　　要：铁路工程勘察过程中会产生大量的基础地质数据,如何实现多源异构地质数据重构汇聚、结构化存储管理以及数字化服务是工程勘察数字化转型与协同设计的关键。本文充分融合GIS、BIM、数据湖、微服务等新一代信息技术,研究并设计多源异构地质数据的结构化存储数据结构;同时,基于该套数据结构,研发集地质基础数据库、数据汇聚管理、数据服务于一体的地质数据管理与服务系统。系统具备基础地质信息GIS时空融合可视化与场景配置能力,采用基于gPRC的微服务架构实现点、线状区域的地质信息综合查询统计分析与下载服务、虚拟钻孔图切剖面的自动生成与即时服务、多种GIS与BIM格式的模型适配服务,实现二、三维地质数据及模型数字化集成、一体化存储、精细化管理和即时按需服务,为铁路工程地质数据融合奠定了数据基础。在宜涪(宜昌—涪陵)铁路项目中的应用结果表明,多源异构地质数据通过重构与集成,形成了高实用性、可扩展性及灵活自助数据服务,显著增强了铁路工程勘察设计业务的数字化水平,提升勘察设计的效率和质量,为其他地质信息系统的设计与开发提供参考。During the railway engineering survey,a large amount of basic geological data will be generated.How to achieve the reconstruction and aggregation of multi⁃source heterogeneous geological data,structured storage management and digital services is the key to digital transformation and collaborative design in engineering survey.This article fully integrates new generation information technologies such as GIS,BIM,data lakes,and microservices,and studies and designs the structured data storage structure of multi⁃source heterogeneous geological data.At the same time,based on this data structure,an integrated geological data management and service system is developed,which includes geological basic databases,data aggregation management,and data services.The system has the ability to visualize and configure basic geological information in GIS spatio⁃temporal context,and uses a microservice architecture based on gRPC to achieve comprehensive query and statistical analysis of point and linear regional geological information with download services,automatic generation and instant services of virtual drilling maps and sections,and model adaptation services for various GIS and BIM formats.It has achieved digital integration,integrated storage,fine management,and instant on⁃demand services for 2D and 3D geological data and models,laying the foundation for railway engineering geological data fusion.Application results in the Yifu(Yichang⁃Fuling)railway project show that multi⁃source heterogeneous geological data can be reconstructed and integrated to form highly practical,scalable,and flexible self⁃service data services.This not only significantly enhances the digitalization level of railway engineering survey and design business,improves efficiency and quality,but also provides references for the design and development of other geological information systems.
