PROBLEM TO BE SOLVED: To provide a soil-column execution system in which a soil column having fixed vertical bearing capacity can be executed easily by arbitrarily changing the diameter and number or the like of the diameter of the small diametral section of the soil column. SOLUTION: In the soil-column execution system being used in relation to a soil-column execution device executing the soil column in a ground and having an auxiliary system for selecting the optimum soil column from at least one kind of the soil columns to be executed, the auxiliary system is composed of (i) a shape-data storage section, in which shape data related to the size and shape of the soil column to be executed are input and stored, (ii) a geological- data storage section, in which geological data related to geology, in which the soil column is executed, are input and stored, (iii) an arithmetic section receiving the shape data of the shape-data storage section and the geological data of the geological-data storage section and predicting characteristic data that the soil column to be executed can have when the soil column is executed to the ground, and (iv) an output section displaying the characteristic data in relation to the shape data.
