【 摘 要 】

The dynamic replacement method is appled widely to the soft soil treatment, but is seldom used in retificating pile deviation. By the ways of dynamic replacement method gravel block can form underground, the gravel block can be treated as reaction-froce base, the magnitude of squeeze force needed for retificating pile deviation is related to the scale of gravel block. Take a sheet pile retaining wall for instance, the treatment scheme and paramters calculating method for deviation rectification of support pile was put forward. The project case demonstrate that this method is effective when the layout of gravel column is reasonable to a certain degree, it is a good reference to similar projects.
