ABSTRACT
With the acceleration of urbanization in China, high-rise and super-high-rise buildings continue to emerge, so pile foundation has been widely used. To ensure the safety of buildings during use, it is necessary to study the stability of pile foundations. In this paper, elastic modulus, Poisson ratio, angle of internal friction, and friction coefficient of pile-soil interface are selected as the factors affecting the stability of pile foundation for sensitivity analysis. According to the load-settlement curve obtained from field experiments, a finite element model is established. The sensitivity analysis of the influencing factors was carried out by manipulated variable experiment and orthogonal experiment. Finally, the degree of influence was ranked as follows: Poisson ratio > friction coefficient > elastic modulus > angle of internal friction.
