PROBLEM TO BE SOLVED: To provide a construction method for an earth-retaining structure capable of shortening the construction period and of reducing the construction cost. SOLUTION: After connecting a tensile member 13 made of chains to an earth-retaining panel 2, a backfilling material 14 is carries into the rear of the earth-retaining panel 12 so as to cover the tensile members 13. Depending upon the tensile member 13, a rolling motor vehicle 15 is travelled in a state that the earth-retaining panels 13 are stabilized, and the backfilling material 14 is roll-compacted from the above. The rolling motor vehicle 15 is kept to non-contact state by the panel 12 and travelled to a position close to a travelling possible, the backfilled material 14 carried in is firmly compacted. By performing the rolling work for the backfilling material 14 by the rolling motor vehicle, the amount of backfilling material 14 can be increased and the number of rolling processes can be reduced and the construction period can be shortened and construction cost can be decreased.
