Abstract
A caisson sinking method comprises the steps of excavating the ground to make a support ditch having the same plan-view shape as a caisson to be sunk, casting into the excavated ditch a bearing material that can carry the caisson as supported in the ditch but collapses easily by itself, placing entire tapered bottom edge of the caisson on the bearing material cast in the support ditch as aligned therewith, and sequentially removing the bearing material immediately below the bottom edge of the caisson, the caisson being thereby smoothly sunk down to a caisson sinking position without any tilting of the caisson.
