Abstract
Centrifuge modeling has become a popular and powerful experimental tool in geotechnical engineering. The centrifugal acceleration, which is used to simulate the gravitational acceleration, varies within a model in both magnitude and direction. As a result, the stress field in a centrifuge model is different from that in the prototype being simulated. This paper presents the results of a numerical simulation of the effect of the variation in radial centrifugal acceleration on the stress distribution in a centrifuge model, and its impact on the accuracy of test results. The influence of the centrifuge radius and the size of a model container is investigated.
