| Abstract: |
| Based on four project cases of vibro casing cast-in-place pile in silty sand foundation, the liquefaction of sand and its consequent pile breaking are analyzed, and suggestions on how to adopt values of the design parameters of a single pile are presented. |
| Key words: silty sand foundation,vibro casing cast-in-place pile,sand liquefaction,pile breaking,design parameters of a single pile |
