Multifunctional soil frost heaving deformation measuring device

The utility model provides a multifunctional soil body frost heaving deformation measuring device, including sample chamber, soil body test piece, bottom plate and top plate, sample chamber is transparent cylindrical barrel made of organic glass material, on the sample chamber is vertically inserted with a plurality of thermistor temperature sensor, the bottom plate is provided the sample chamber bottom, and the top plate is provided with a plurality of thermistor temperature sensors. The top plate is arranged at the top of the sample cavity, and the soil body test piece is arranged in the sample cavity. Compared with the prior art, the device has the advantages that the temperatures of the bottom plate and the top plate of the device can be adjusted, soil layer temperature distribution simulation across 0 DEG C can be achieved, frost heaving deformation of different soil textures under the same temperature field can be detected, and the device is used for preferably selecting a soil solidification process sc
