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.
