CALCULATED FORECAST ON INTERACTIONS OF AUGERCAST ANCHOR PILES WITH A SILTY-CLAYEY FOOT
Abstract
The paper describes a solution to the problem of strengthening the bulkhead wall of an underground three-storey parking by means of additional arrangement of augercast anchor piles in the upper part. An analysis of static tests’ results for augercast anchor piles is given with drawn up graphs showing dependency of the piles’ setting on the applied load. Calculations are performed to determine the main anchor pile parameters as per results of numerical simulation: length, spacing and load bearing capability. It is possible to use Plaxis 2D programming complex for numerical simulation of joint functioning of the bulkhead wall and the augercast anchor piles. The results of analytical calculations described in this paper will allow to determine displacement of an augercast anchor pile caused by pulling-out load as compared to control on-site static tests in clayey soil with an accuracy of up to 22 %.
