The utility model provides a device for testing the passing ability of a vehicle on a soft ground, and the device comprises a sampling assembly which comprises a sampling handle, a connecting rod and a sampling head which are sequentially connected from top to bottom, and the end, away from the connecting rod, of the sampling head is provided with a sampling port; the soil sampler further comprises a sample pushing rod, one end of the sample pushing rod sequentially penetrates through the sampling handle and the connecting rod and then extends into the sampling opening, and the sample pushing rod can longitudinally move relative to the side wall of the sampling opening and is used for pushing out soil in the sampling opening. Under the condition that a vehicle cannot perform multiple repeated tests on a certain ground, soil on the ground to be tested can be taken out through the sampling assembly, then the soil is moved to a position far away from the ground for subsequent measurement, the flexibility is high
