Since the bearing capacity of drilled-shaft is greatly affected by the slime around pile tip, the tip grouting is often used by the industries. However, the whole process of this technique needs to be verified. The study herein provides the numerical results using discrete element program PFC^(2D) to simulate the tip grouting and finite element computer software Sigma/W in GeoStudio 2004 to model the pile load test according to the field measured data, which help us better understand the variation of pile head settlement and frictional resistance during the pile load test.
