  • The self-weight collapsible deformation of loess is harmful to the upper buildings. The existing indoor collapsibility and on-site water immersion test method for loess are difficult to satisfy the requirements of the project construction in terms of the economy, duration and accuracy of the test results. Based on the typical-stratigraphic centrifugal model test method, with the self-weight collapsible loess foundation of Buli Village, Weicheng District, Xianyang City as the object, a multi-stratigraphic centrifugal model test method for determination of loess self-weight collapsible deformation is proposed, and the results of the indoor collapsibility tests and on-site water immersion tests are compared. The stratified deformation characteristics of Q2 and Q3 loess self-weight collapsibility are also analyzed. The results show that the value of the regional correction coefficient β0 obtained from the multi-stratigraphic centrifugal model test is different from that obtained from the on-site water immersion tests with a difference of 0.04, and the relative error is 2.5%. It is proved that the multi-stratigraphic centrifugal model test method can be used to obtain similar results with the on-site water immersion test, and has the advantages of low cost and short test cycle. Thus, under some circumstances, it can replace the on-site immersion tests to determine the self-weight collapsible deformation of loess.
