Numerical Analysis of Drilling Process of Bored Pile in Seasonal Frozen Ground in the West of China

Abstract:

In order to research shrinkage of hole-wall and plastic region around hole-wall of bored pile in drilling process, a porous analysis model was built, and drilling process of bored pile, under dry excavation technology and hydraulic excavation technology, were simulated by element birth and death feature in ADINA software. Numerical analysis results show that to seasonal frozen ground in the west of China, dry excavation technology is not appropriate, consolidation settlement caused by drilling is small and can be taken into no consideration in design, major problem in hydraulic excavation technology is shrinkage of hole-wall, which mainly influenced by density of slurry and excavation depth one time.
