| Abstract: | In this paper, the cause of deviation and lean of vibro-driven cast-in-place foundation in a project was analyzed, the conclusions were made that pile deviation and lean were caused because of improper retaining and protecting for foundation excavation and super heaped load on the pile foundation, a reinforcement measures and its main construction procedure on strengthen of destabilized pile foundation was given, these data from settlement observation proved that the effect of reinforcement is very good. |

| Keywords: | deviation super heaped load static press anchor pile reinforcement settlement observation |
