Estimation of Pile Friction Degradation from Shearbox Tests

CODEN: GTJODJ

Abstract

An uncemented carbonate sand has been subjected to cyclic loading in a modified shearbox apparatus under constant normal load and constant normal stiffness conditions. The behaviour in the tests using a constant normal stiffness shows many similarities with the variation of skin friction on piles under cyclic loading. It is demonstrated that the response in the shearbox tests with a constant normal stiffness may be predicted from the response observed in conventional shearbox tests, and that conventional shearbox tests can thus provide valuable information on the degradation of skin friction of piles under cyclic loading.
