Zusammenfassung:The present invention relates to an unsaturated zone ground simulation device by which, when an unsaturated zone, of which the depth varies according to the fluctuation of rainfall and groundwater level, is simulated, the length of the unsaturated zone ground simulation device is selectively adjusted and fluid inflow/discharge and characteristic evaluation are available at various points, thereby accurately evaluating the physicochemical and biological properties of the unsaturated zone. The unsaturated zone ground simulation device according to the present invention comprises an upper column part, a middle column part, and a lower column part which are arranged and combined in the vertical direction so as to simulate an unsaturated zone. The middle column part comprises a plurality of unit columns. By adjusting the number of the unit columns forming the middle column part, the lengths of the ground simulation device and the unsaturated zone can be matched in scale, and the ground reflecting the properties along the depth direction of the unsaturated zone is simulated in each unit column. 본 발명은 강우량 및 지하수위 변동에 따라 깊이가 변동되는 불포화대를 모사함에 있어서 지반모사장치의 길이가 선택적으로 조절되도록 함과 다양한 지점에서의 유체 유출입 및 특성평가가 가능하도록 함으로써 불포화대의 물리화학적 특성 및 생물학적 특성을 정확하게 평가할 수 있는 불포화대 지반모사장치에 관한 것으로서, 본 발명에 따른 불포화대 지반모사장치는 수직방향을 따라 배열, 결합되어 불포화대를 모사하는 상단 컬럼부, 중단 컬럼부 및 하단 컬럼부를 포함하여 이루어지며, 상기 중단 컬럼부는 복수개의 단위 컬럼으로 구성되며, 중단 컬럼부를 구성하는 단위 컬럼의 개수 조절을 통해 지반모사장치와 불포화대의 길이를 축척상 일치시킬 수 있으며, 각각의 단위 컬럼 내에 불포화대의 깊이 방향에 따른 성상을 반영한 지반을 모사하는 것을 특징으로 한다.
