上拔荷载作用下挤扩支盘桩颗粒流数值模拟
Numerical Simulation on Particle Flow of Squeezed Branch Pile under Uplift Loading
摘要
Abstract
Based on particle flow theory, load-pile displacement relationship, soil deformation and distribution of foundation displacement field when squeezed branch pile under uplift loading in clay foundation are sludied using PFC2D program. The resulls show [hat load-pile displacement curve is classified into initial elastic stage, intermediate plastic stage and failure stage. Sliding face caused by soil failure is mainly from the tip of lower branch into ground surface along oblique direction. Soil particles are affected within inverted bell-shaped area.关键词
