Abstract:

Due to the complexity of drainage consolidation of red clay foundation, we simulated and analyzed the consolidation settlement by using the consolidation calculation module Soils and modified Cambridge model of ABAQUS/Standard. The reconstruction project of an aluminum factory was taken as an example. The variation of red clay foundation’s settlement with time, the dissipation of pore water pressure, the non-linear distribution of void ratio with depth, and the effective stress growth of soil were researched. Results suggest that the calculated results are in good agreement with the law of soil mechanics, and the actual situation of the red clay foundation consolidation settlement could be reflected accurately. This research provides references for the foundation treatment and engineering design of buildings on red clay ground.

Key words: red clay foundation, ABAQUS, modified cam-clay model, consolidation settlement, pore water pressure
