| Abstract: | 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 q u of pile shaft material, compression modulus E s 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. |
