Influence of construction of test pool on adjacent piles

The Mohr-Coulomb’s model and the contact surface model are adopted to simulate the characters of soils and the interaction between structures and soils respectively. A 3D finite element model based on the interaction of pool and piles is established by ABAQUS software. The displacement of latticed concrete diaphragm wall and the additional distortion of adjacent piles during the construction state and the service state are analyzed. Finally, comparisons indicate that the piles have a positive effect on the concrete diaphragm wall. Through this study, the basic knowledge of the interaction between the pool construction and the adjacent piles are initially obtained, and it will be significant to the improvement of theories for piled foundation design.
