Background

When water conservancy thrives, the harvest is rich. China has 98,000 reservoirs, including 4,700 large and medium-sized ones. They play major roles in flood control, ice-jam prevention, storage, water supply, and power generation. Dams work together with reservoirs, hydropower plants, and other hydraulic hubs to stabilize urban development. Digital twins supply real-time sensing data for dam safety management and strong support for flood prediction and timely critical decisions. Digital-twin water conservancy is a new idea and model for smart water conservancy—a new technical path that will draw more industrial strength and intellectual resources into a basin-scale innovation platform.

Solution

By fusing its own software with a Sugon computing platform, the China Institute of Water Resources and Hydropower Research (IWHR) successfully built a dam digital twin. On the Sugon platform, the dam is simulated in virtual space across time, space, materials, and cost to predict dam capacity in advance, contributing to safer development of China’s water sector.

Customer Benefits

On the Sugon computing platform, users for the first time built a sub-meter-resolution fine finite-element model of the Three Gorges Project that fully reflects detailed structure and complex geological conditions; for the first time completed simulation analysis of the full dam’s temperature, deformation, and stress fields and dynamic analysis under extreme seismic load, achieving comprehensive performance assessment under normal operation and extreme earthquake conditions; and for the first time built a cross-scale finite-element model of an optomechanical-device foundation and target sphere, completed full-system simulation of the optomechanical device, and achieved high-precision assessment of vibration characteristics and stability.
