Zusammenfassung:PROBLEM TO BE SOLVED: To prevent lining concrete from being cracked because the temperature of the lining concrete drops due to cooling by water or vapor for use in curing. SOLUTION: The curing method for the lining concrete for the tunnel, which is molded by using a travelling form, comprises a first step of curing the lining concrete without adding moisture, after the removal of forms, and a second step of curing the lining concrete by adding the moisture. The first step is performed by covering a lining concrete surface with an impermeable sheet, and the second step is performed by supplying the water or the vapor to the lining concrete surface.
