Sažetak

How can people predict the sedimentation of tall buildings and analyze the foundation rebound to protect underground utilities? This is the urgent problem in today's construction. To solve it, this paper is dedicated to analyzing how piles affect the foundation rebound value by using Mohr-Coulomb Model and the 3D emulation calculation software FLAC3D with 20-meter-deep foundation pits as an example. The study shows that the distribution pattern of the foundation rebound without piles is a convex curve while piles make the curve go corrugated with the foundation rebound value shrieking by 0,4÷0,6. Also, parameters such as the distance of the piles and diameter of the piles and length of the piles have an effect on the value in a way that the increasing distance lowers the piles' restriction on the foundation rebound value. Therefore, this paper suggests that the largest distance between piles should be no more than 6d when the restricted extent of the value is about 0,23÷0,37. Raising the diameter and length of the piles (no more than 1,25 times of the digging depth) can restrict rebound effectively. Therefore, this paper concludes useful parameters in pile design, proves its mechanism for restriction on foundation rebound, and provides analytical basis for optimization of the piles.
