What is
Prowd Warning?
The Prowd Real-time Early Warning Platform for Excavations is a safety warning system for excavation projects, built on the mobilisable strength theory and cognitive digital twin technology. This platform offers autonomous modelling and visual interaction capabilities, enabling users to customise the excavation geometry, support structure types, and geological parameters according to project-specific requirements. By integrating mobilisable strength theory with real-time monitoring data, the system dynamically analyses the deformation and stability of both the soil and the supporting structures. This allows for the establishment of an automated, rapid-response mechanism that provides intelligent predictions regarding excavation safety and delivers graded early warnings. The system has been successfully deployed in several deep excavation projects in China, offering comprehensive safety warning support in complex geological environments. As the software is still a work in progress, we welcome any feedback or suggestions to enhance its functionality and usability in engineering practice.
