Analysis of Settlement of Soils around Tapered Piles in Compressive Clay of Minsk Region

Abstract

Presented in this research paper are the results of a comprehensive investigation on the analysis of settlement of soils around axially loaded tapered piles in compressive clay soil. The results show the influence of tapering of the circumferential dimension of instrumental piles on the magnitude, pattern and orientation of settlement of soils around loaded modeled wooden and reinforced concrete piles bored into compressive clay soil. With the same pile spacing (η), while a reduced tapering angle (α) gives a less depth of failure zone, it produces a larger horizontal displacement of soil than corresponding piles with a higher tapering angle. Settlement of tapered piles among other things is influenced by the tapering angle (α) relative to the diameter of the pile, and this effect increases with incremental depth of pile penetration into compressive clay soil. In addition, pile cap settlement is 5-10 % higher in tapered piles with lower tapering angle.
