  • Centrifuge-stopped loading method and acceleration-variable centrifuge-run loading method were carried out by using TLJ-2 geotechnical centrifuge, the settlement characteristics of medium compression soil foundations of Haidong High-speed Railway and Jiaoji High-speed Railway were researched and compared with that of field-filling tests, and the main factors influencing the precisions of predicting prototype foundation settlement with centrifuge tests were studied.Research result indicates that the settlements from centrifuge tests are larger than that from filling tests, and their correction factors decrease and the settlement differences increase with the increase of foundation depth.The settlements within 6.0 m from filling tests are more than 45% of total settlement, but the settlements from centrifuge tests are less than 20% of total settlement.The properties of the settlements from two centrifuge tests are similar, the settlements in subgrade filling are 88% of total settlements, but the settlement from the first method is about twice of that from the second method.Obviously, it is very hard to predict the foundation settlement of medium compression soil by using centrifuge tests, but the tests can be used for qualitative analysis.
