Provided is a multi-step injection material injecting method by depth using a GIN method. The multi-step injection material injecting method by depth using a GIN method comprises: a step (a) of performing a boring investigation and a hydraulic test on the ground into which an injection material is to be injected; a step (b) of deriving a geological formation result by the depth of a borehole; a step (c) of determining a GIN value by depth according to the property of a geological formation, and determining a maximum injection pressure and maximum injection amount by depth; a step (d) of generating data for generating a GIN curve based on the calculated GIN values, the maximum injection pressure, and the maximum injection amount; a step (e) of detecting a current injection pressure and current injection amount at the corresponding depth while injecting the injection material into the borehole by a determined injection pressure; a step (f) of comparing the detected current injection pressure and current injection amount with the injection pressure and injection amount of the GIN curve; and a step (g) of injecting the injection material until the current injection pressure and current injection amount reach to the injection pressure and injection amount of the GIN curve, wherein the injection material to be injected is not injected along the GIN curve, but is managed by a box so that the injection management of the injection material of which the injection pressure and injection amount are determined within the box in the injection step by the corresponding depth can be performed.
