Abstract: A measurement system for measuring a subgrade reaction coefficient of a plurality of layers having different depths in a ground is provided. The system includes an object provided on a ground surface of the ground. An earth pressure gauge measures an earth pressure of the plurality of layers with respect to a load of the object. A settlement gauge measures a settlement amount of the plurality of layers with respect to the load of the object. The disclosed technology calculates the subgrade reaction coefficient of the plurality of layers on the basis of the earth pressure and the settlement amount.
