Geotechnical Centrifuge
Geotechnical centrifuges, based on the principles of model scaling effect and stress equivalence, are widely adopted for experimental research on the design and protection of dams, slopes and other engineering structures. The research team has developed nearly all large‑scale geotechnical centrifuges in China since the 21st century, with its development technology ranking among the world’s top tier and holding a domestic leading position. A product portfolio covering capacities from 25 g·t to 1900 g·t has been established. The relevant products have played a vital role in major engineering projects including the Three Gorges cofferdam, the South‑to‑North Water Diversion Project, deep‑sea oil and gas exploitation, disaster prevention and mitigation, and pollution control.
