AI Technical Summary

Technical Problem

Existing 3D GIS systems are difficult to effectively combine BIM and GIS to achieve visualization integration, quantitative analysis, collaborative application, and digital management of multi-source heterogeneous data. They cannot meet the multi-disciplinary and cross-stage collaborative needs of geotechnical engineering investigation and design, thus affecting the digitalization level of investigation and design enterprises and the efficiency of urban underground space development and management.

Method used

By lightweighting multi-source, multi-professional, and multi-type geotechnical engineering BIM data and geographic information data, a standard format lightweight BIM model is formed. This model is then visualized, integrated, and quantitatively analyzed. Collision analysis is performed using a virtual pile layout module to generate a pile foundation model. Pile foundation bearing capacity and settlement deformation analysis are then conducted, enabling digital delivery and management of the data.

Benefits of technology

It has improved the scientific rigor and reliability of survey and design schemes, reduced potential engineering risks, enhanced the reliability and digital management level of survey and design results, provided precise data support and a visual browsing platform for all parties, and promoted the application of smart cities.
