Summary:PROBLEM TO BE SOLVED: To provide a slope reinforcing method improved in earthquake resistance. SOLUTION: The slope reinforcing method includes steps for excavating and leveling a slope 12 on which first stage precast concrete plates 11 are disposed; disposing the precast concrete plates 11; filling grout 30 in the clearance between the precast concrete plates 11 and the slope 12; forming an excavated hole 28 from the precast concrete plate 11 to the slope 12; inserting a reinforcing bar 29 into the excavated hole 28 and filling grout 32; and anchoring the end of the reinforcing bar 29 for connection to the precast concrete plate 11. Construction after the second stage includes continuously repeating the respective steps and introducing a tensile force after connecting a PC steel bar 19a of a precast concrete plate 11a to a PC steel bar 19 of the precast concrete plate 11 located in the upper stage in performing the step for disposing the precast concrete plate 11a on the slope 12.
