The pluviation method is a widely used model preparation technique for the centrifugal test of sandy soil layers and structures. The degree of compaction and uniformity are the key control objects and are directly related to the accuracy and reliability of the test results. Based on the pluviation device, control elements, uniformity test, and other aspects, the research progress and key problems of preparation technique of centrifugal pluviation model at home and abroad, and the structural composition, control characteristics and basic classification of existing pluviation devices were summarized, and the range of steady-state compactness and the key factors were expounded. The advantages and disadvantages and normalization evaluation criteria of different measurement and evaluation methods of spatial uniformity model were reviewed. Based on the current status and shortcomings, the development direction and trend of preparation technology of centrifugal pluviation model were discussed.
