Abstract
The pile friction regular pattern in the slope has much difference with piles in the ground. By using the finite-difference software FLAC3D,the pile friction under the vertical load is studied. The regular pattern and influence factors are analyzed. The results show that there is a significant difference contrasting the friction of both sides of the pile. For the point of value, the friction closed to the slope-side is smaller than the friction away from the slope-side. The average is 60% to 70%. For the distribution, the friction closed to the slope-side decreases rapidly with the depth of the pile. The friction away from the slope-side distributes relatively evenly. The slope ratio and the pile location have a great impact on the friction. The friction has a negative correlation with the slope ratio, and has a positive correlation with the pile distance.
