Claim Text:
1. A test apparatus for early landslide detection fully-connected with pore water pressure, surface displacement and shear surface, the test apparatus comprising: a frame; a flume installed on the frame so as to be adjustable in angle, the flume providing a slope for landslide materials; a slider coupled to the flume so as to be movable in a longitudinal direction of the flume, with a soil mass loaded into the slider, the soil mass constituting the landslide materials, the slider providing a shear surface of the soil mass, wherein the slider moves along with the soil mass in the longitudinal direction of the flume and simulates a surface displacement of an upper part of the soil mass and a slope failure of a lower surface of the soil mass; and a calculation unit calculating shear strength and shear stress on a failure plane of the slope based on pore water pressure and weight of the soil mass depending on the movement of the slider, and calculating a factor of safety of the slope based on the calculated shear strength and shear stress.
