Abstract:

A model test of single pile static load has been carried out through visualization model box. Considering some influence factors, such as the different diameters of piles and different soil compactnesses, the settlement mode of single pile, the behaviour of skin friction resistance and pile-tip resistance with penetration are researched. Through screen and image-processing technology, the change rule of porosity in pile tip and pile-surrounding soil is researched too, through exploitation the process of planar particle flow code ,simulation the pile-tip resistance and the change rule of porosity in pile tip and pile-surrounding soil. The results show that the simulation using method of particle flow code can preferably simulate the process of static load of single pile and post the mechanisms of macro-scale and meso-scale of static load of single pile.

Key words: single pile, static load, model test, numerical simulation by particle flow code, pile-tip resistance
