The construction of an online finite element analysis platform enables real-time simulation of the theoretical deformation and stress states of CFRD based on actual conditions

providing a basis for dam safety diagnostics. Leveraging years of dam monitoring data

the Duncan-Zhang E-B model and creep model parameters for the rockfill are subjected to inversion analysis to obtain the platform′s default calculation parameters. By constructing an automatic invoking interface for the calculation program

the platform ensures timely responses to front-end task requests. To ensure a lightweight web interface

surface models and results are extracted based on the topology information of elements in the mesh. The mesh and results are displayed using the X3DOM to ensure the portability of the platform. This platform is user-friendly and intuitive

providing a solid foundation for real-time

comprehensive monitoring of the dam′s operational status.
