A Theoretical Solution for Pile-Supported Embankment with a Conical Pile-Head

This paper, with a focuses on the pile-supported embankment with a conical pile-head, proposes a theoretical solution which incorporates all the load transfer mechanisms, namely the soil arching effect, the pile−soil interaction, and the support from the substratum, whilst an improved cyli...
