Abstract:

Based on the dredger fill foundation of a project in Hangzhou Bay, the subsidence features of the foundation were obtained through site tests. The finite element modeling (FEM) numerical simulation method was used to simulate the settlement of the dredger fill foundation. The effect of prestressed highintensity concrete (PHC) piles applied to ground treatment of the dredger fill was evaluated reasonably. Evaluation results show that PHC piles applied to ground treatment of dredger fill can obtain a significant  reinforcement effect.

Key words: prestressed high-intensity concrete (PHC) piles, dredger fill, foundation, settlement, reinforcement
