The present invention relates to a testing apparatus for an early landslide detection and, more particularly, to a testing apparatus for an early landslide detection with a fully coupled displacement-pore pressure-slip surface analysis, capable of easily detecting a landslide through the prediction of a safety rate change according to the fine deformation of the ground by calculating the safety rate of a sloping surface based on the change of a shear surface and the displacement and pore pressure of a soil mass. According to the present invention, the shear stress and the shear strength are calculated based on the weight and the pore pressure and the shear surface and the displacement environments are provided by moving a cart comprising a slider to load the soil mass. Thereby, the landslide is early detected through the change of the safety rate and the safety rate is calculated according to the displacement and pore pressure. 본 발명은 산사태 조기탐지 시험장치에 관한 것으로, 더욱 상세하게는 토체의 간극수압과 지표변위 및 전단면의 변화를 기반으로 사면의 안전율을 산출함으로써 지반의 미소변형에 따른 안전율 변화의 예측을 통해 산사태의 조기탐지를 도모할 수 있는 간극수압-지표변위-전단면 완전연계 산사태 조기탐지 시험장치에 관한 것이다. 본 발명에 의하면, 슬라이더를 구성하는 수레에 토체를 적재한 상태로 이동시킴으로써 전단면 및 지표변위 환경을 제공하면서 간극수압 및 중량을 기반으로 전단강도 및 전단응력을 산출할 수 있으며, 이에 따라 간극수압 및 지표변위에 따른 안전율을 산출함과 아울러 안전율 변화를 통해 산사태의 조기탐지를 도모할 수 있다.
