Numerical Analysis of Influences of Engineering Piles for Anti-Inrush of Deep Excavation under Confined Water
Aiming at the problem of anti-inrush of confined water in foundation pits considering the influence of engineering piles, a three-dimensional numerical analysis model of anti-inrush stability of deep foundation pits is established by using the finite element software ABAQUS, and the inrush failure mechanism and deformation behavior of the foundation pit bottom under the action of different confined water levels are analyzed. The effects of different pile lengths, pile spacing, waterproof layer thickness, and soil strength are studied, respectively, and the laws of pile foundation stress and soil deformation under the action of confined water are revealed. The results show that the existence of engineering piles has an obvious inhibitory effect on the stability of foundation pit confined water against inrush. By introducing the comprehensive correction coefficient of pile side friction, an analysis method for the anti-inrush stability of foundation pits considering the influence of engineering piles is proposed.
