Abstract: To evaluate the settlement problem of loess-filled venues, a series of high pressure consolidation tests was conducted on the remolded loess of different initial water contents and dry densities. It is found that the ratio of load to dry density p/?d is linearly correlated with the applied loading, based on which a settlement prediction model of filled venues of different thicknesses (loads) is established. The model has two parameters, namely, k and b. Parameter k decreases with the increase of initial moisture content w0 or initial dry density ?d0, satisfying a relationship among the three variables (i.e., ?d0 k + w0=1); whereas parameter b depends mainly upon the initial dry density and decreases with the increase of initial dry density. Compared with the previous compressive deformation calculation models based on the relation between void ratio and loading, the proposed method which has a higher precision fitting with experimental data shows a stronger correlation, showing that it is more suitable for the calculation of compression deformation of remolded loess.
