The invention discloses a ground uniform settlement structure and a construction method in order to overcome the defects that indoor ground settlement is nonuniform and consequently normal use of buildings is affected. The ground uniform settlement structure comprises engineering piles and cast-in-situ members. Pile end support stands are disposed on the engineering piles; each cast-in-situ member comprises an L-shaped guiding portion and a long strip supporting portion; limiting parts are arranged at the edges, close to the engineering piles, of the supporting portions in a casting mode correspondingly; abutting joint plates which are opposite to the limiting parts are disposed on the upper portions of the pile end support stands on the engineering piles; the outer side faces of the limiting parts are limiting planes; buffer pads are mounted between the limiting planes and the abutting joint plates; the guiding portions are disposed on the outer sides of the pile end support stands; prestress springs are connected between the supporting portions and the pile end support stands; arched reinforcing ribs are disposed between the guiding portions of every two adjacent cast-in-situ members; compacted soil is located under the cast-in-situ members; deep fill soil is buried between the guiding portions of every two adjacent cast-in-situ members; rigid ground is located between the supporting portions of the every two adjacent cast-in-situ members; and inserting ribs are connected between the rigid ground and the supporting portions.
