PURPOSE:To obtain a given bearing capacity by a method in which next stage soil layer is formed, a drawing force is applied to at least one reinforcement, and if the reinforcement is drawn out, a reinforcement having larger surface area than that of a reinforcement to be set on the next soil layer is used. CONSTITUTION:Soil is banked on the ground 14 where a banking is to be constructed and compacted to form the lowest soil layer 16, and reinforcements 18 are set with a spacing on the soil layer 16. Soil is then banked on the layer 16 and compacted to form the next stage soil layer 20, and a drawing force is applied to at least one reinforcement 18. In case where the reinforcement 18 is not drawn out, the reinforcement 18 similar to one set on the layer 16 is set on the soil layer 20. In case the reinforcement 18 is drawn out, the reinforcement 18 having a larger surface area is set on the soil layer 20 for construction of banking 10. |
