Abstract
Aiming at special method of installation of rammed soil-cement piles,a new type of strain transducer in pile was proposed.And then,based on loading test data of rammed soil-cement single piles,load transfer behavior of rammed soil-cement piles and distribution of shaft resistance in single pile are studied.Results show that transmission of loads along pile are limited to a certain range at the shallow depth due to limited strength of rammed soil-cement pile.The deformation,axial load,distribution of shaft resistance occurred mainly within this range;and the varying gradient of every variable is larger.
