Abstract EN
Lateral displacement of pile foundation is crucial to the safety of an overall structure.
In this study, a numerical simulation on the lateral displacement of pile foundation under stacking loads was conducted to determine its relation with different influencing factors.
Simulation results demonstrated that stacking loads at the pile side mostly influence the lateral displacement of pile foundation.
The lateral displacement of pile foundation increases by one order of magnitude when the stacking loads increase from 100 kPa to 300 kPa.
Other influencing factors are less important than stacking loads.
Lateral displacements of the pile body and at the pile top can be reduced effectively by increasing the deformation modulus of surface soil mass, reducing the thickness of soft soil, and expanding pile diameter.
Our analysis indicates that a nonlinear relationship exists between the lateral displacement at the pile top and the pile diameter.
The lateral resistance of the pile body can be enhanced by coupling the stacking load along piles and the axial force at the pile top.
An actual large-scale engineering project was chosen to simulate the effects of postconstructed embankment on lateral displacement and axial force of bridge pile foundation under different construction conditions and to obtain the lateral displacement of the pile body and the negative frictional resistance caused by soft soil compression under stacking loads.
On the basis of the calculated results, engineering safety and stability were evaluated, and a guide for the design and construction was proposed.
