The invention discloses a fill settlement prediction method based on a centrifugal
model test, and relates to the technical field of fill
engineering, and the method comprises the following steps: S1,setting a special model box for a fill
engineering settlement test, and enabling the interior of the model box to be a separation model space; S2, manufacturing a centrifugal
model sample of the
engineering key node, and manufacturing a centrifugal
model sample of general regularity research of the multi-parameter influence; S3, performing
data transmission with a centrifugal
machine in the modelbox, and completing a personalized
model test and a generic
model test; and S4, drawing a space scatter cluster, performing fitting, performing
smoothing and generating a three-dimensional space curved surface. According to the method,
time cost and economic cost are saved, fill settlement of objective entity working conditions can be simulated in advance, and the method can be used for comparison and selection of multiple alternative schemes and optimization of design parameters; three parameter relations related to settlement can be established at the same time, a space curved surface is formed, and tedious operation of
field tests or numerical calculation is avoided.
