  4. Abstract:
  5. This study numerically investigates the side resistance of drilled shafts (bored piles) in sand using FLAC2D computer program. The results of the equations available in the literature are compared with the results of the present numerical study. A series of analyses is also conducted to assess the effects of various soil and pile parameters on the magnitude of side resistance of bored piles embedded in sand. Furthermore, the coupling (combined) effect of coefficient of lateral earth pressure with friction angle, and the coefficient of lateral earth pressure with a unit weight of soil on side resistance are investigated. The results show that the maximum effect of K0 on side resistance occurs around the soil friction angle of 40° and 45°. Also, the effect of K0 on side resistance is approximately constant by increasing the soil unit weight. Finally, a correction factor for coefficient of lateral earth pressure is determined. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group
