Abstract
The utility model discloses a tester for simulating the influence of a whole root system on the shearing strength of soil. The tester comprises a square box for carrying sample soil and root system parts, wherein the square box comprises an upper box and a lower box which are overlapped together, one end surface of the upper box is connected with a tension meter, and the other end of the tension meter is connected with a traction device. The tester can be used for quickly measuring the maximum shear force of the whole root system indoors or outdoors, and a provided model can be used for simulating various different root system structural factors such as the angle of the root system placed in the soil, the distance between the root system and a shear failure surface, the depth of the root system deeply embedded in the soil and the like. The tester is simple and convenient to operate, and the experimental result is reliable.
