PROBLEM TO BE SOLVED: To provide an evaluating method and the like capable of accurately evaluating landslide on a ground formed of stratums of different geologies. SOLUTION: In the evaluating method of the landslide by a three-axis testing method of soil using a three-axis compression device, a specimen 1 is placed in liquid in a three-axis pressure chamber 5P of the three-axis compression device 5, the specimen is placed in a compaction state pressurized from three-axis directions by a cell pressure supply device 8 of the three-axis compression device, and evaluation is performed based on respective main stressesσa andσr and respective effective main stressesσa' andσr' of the axial direction and side direction leading deformation of the specimen when it is compressed from the axial direction by a compression device 20. In a state where the lower surface of the specimen 1 abuts on the upper surface 2A of a columnar mounting stand 2 formed of a rigid body having a groove 2a for drainage axially, the specimen formed so that the whole has a columnar shape extending axially is arranged at a predetermined position in the three-axis pressure chamber, and the three-axis testing method of the soil is performed.
