Drum Centrifuge Model Test for Geotechnical Problems

A centrifuge model test with a 1/N scaled model is performed under a centrifuge acceleration of N times of earth gravity (1 G), so that the same self-weight stress of actual structures can be applied to the prototype. A long extension of the experimental area is one advantage of this test system. It is also possible to perform flume experiments simultaneously modeling the water area and ground/structural parts.

Drum Centrifuge Model Test for Geotechnical Problems

Features

  • Reproduces the same stress and strain as in the prototype in small-scale experiments, making it possible to reduce the cost and time required for experiments.
  • Adoption of a coaxial double shaft system makes it possible to exchange of various types of devices, such as ground preparation device, loading device, etc. while rotating the container, reproducing multi-stage construction processes.
  • Because the water area and ground/structural parts are modeled simultaneously, it is possible to conduct experiments considering soil-water-structure interaction.
  • Wave experiments and tsunami experiments are possible by using the proper wave generator.
  • Detailed photography of the total experimental area is possible by installing multiple high speed cameras.
