specific Embodiment

[0016] Such as figure 1 As shown, it includes three parts. One is the part that carries the sample soil and the root system. This part is a square box made of PVC sheets with a specification of 300*300*200mm and a thickness of 10mm. The box is composed of an upper box, a lower box and a box cover. The height of the upper box is 100mm, and the height of the lower box is 100mm; the second is the part that provides shear stress, which is composed of a tension gauge with a range of 500N and a screw-bracket. A block that can clamp the support is placed at the end; the last part is a wire model placed inside the box to simulate the root system structure.

[0017] The present invention can quickly measure the maximum shear force of the whole root system indoors or in the field, and the model provided can simulate various root system structural factors such as the angle at which the root system is placed in the soil, the distance between the root system and the shear failure surface, ...

Abstract

The invention discloses a test device for simulating the influence of a whole root system on the shearing strength of soil. The device comprises a square box for bearing sample soil and a root system part, wherein the square box comprises an upper box and a lower box overlapped up and down; 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 device disclosed by the invention can quickly measure the maximum shearing force of the whole root system indoors or outdoors; the provided model can simulate various different root system structure factors such as the placing angle of the root system in soil, the distance between the root system and a shearing damage surface and the buried depth of the root system in soil; and the operation is simple and convenient, and an experimental result is reliable.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for simulating the influence of the whole root system on the soil shear strength. Background technique [0002] Different root structure factors have different effects on the soil shear strength, such as the angle at which the root system is placed in the soil, the distance between the root system and the shear failure surface, and the depth of the root system in the soil. [0003] At present, there is no test device for simulating the effect of the whole root system on the soil shear strength, which is simple and convenient to operate and reliable in experimental results. Contents of the invention [0004] The object of the present invention is to provide a test device for simulating the influence of the whole root system on the soil shear strength, which is simple and convenient to operate and reliable in test results. [0005] The purpose of the present invention is achieved t...
