Research on Horizontal Bearing Behaviors of Circular Section Static Compaction Piles

Abstract:

Based on Vesic theory of cavity expansion and Mohr-Coulomb yield criterion,A method was proposed which can be used to calculate earth pressure around circular section static compaction pile.Furthermore, a formula calculating earth pressure around circular section static compaction pile with horizontal displacement was deduced based on hyothesis without relative displacement on pile-soil contact boundary.Finally,according to the research above and force balance condition,an estimation method for horizontal bearing capacity of circular section static compaction pile was gotten.In order to validate the feasibility proposed theory in this paper, a comparative research was carried out.Both experimental and theoretical results indicated that earth pressure on pile-soil contact surface of soil compaction pile was much more than of pile without soil compaction and earth pressure would redistribute with change of horizontal displacement.Moreove,because horizontal bearing capacity calculated by method in this paper accorded with result measured in field very much,the theory in here was feasible.
