Based on the method of load transfer and Geddes formula
this paper calculates the load(Q)-settlement (s)curve of compacted cement-soil single pile. Then the variational regularity of the Q-s curve of a single pile with the pile length l
limit strength qu of pile shaft material
compression modulus Es of soil arround the pile tip are analysed . The relation of compression of pile shaft material
pile end resistance and settlement with the load of pile top are also analysed .
