摘要： Disclosed herein is a test apparatus for early landslide detection fully-connected with pore water pressure, surface displacement and shear surface. The test apparatus calculates a factor of safety of a slope based on variation in pore water pressure, surface displacement and shear surface of a soil mass, and predicts a change in factor of safety, thus making early landslide detection possible. In the test apparatus, while a container of a slider is moved with a soil mass loaded into the container, shear surface and surface displacement environment is provided, and the shear strength and the shear stress of the soil mass can be calculated based on the pore water pressure and the weight of the soil mass. Thereby, the factor of safety of the soil mass can be calculated, and early landslide detection can be realized by using variation of the factor of safety of the slope.
