    • Abstract
  • The elastic subgrade reaction method based on Winkler foundation model is widely used in the analysis of laterally loaded piles currently. However, the soil is regarded as non-continuum and the shear action between soils is neglected in this method, which is not correspondent with engineering practice. A simplified analysis method based on double-parameter foundation model which can consider shear action is proposed for laterally loaded piles. This method successfully takes into account the change of the subgrade modulus with depth. The results show that the effect of shear action cannot be neglected with the increase of shear modulus of soil. Compared with the elastic subgrade reaction method, the proposed method is more rigorous in theory and has higher calculation accuracy.
