The model mainly consist of foundation, soft soil and the jet grouting piles, all of which are connected, simulated by the element of SOLID45 (8nodes). 3.2 Hypothesized material properties Under the normal working loads, the spread foundation can not often reach to the yielding state because of the stiffness, so the material matches the law of Hooke; while the material of soil conforms to the criterion of Drucker-Prager.
