Abstract

The invention relates to an experimental device with a soil horizontal displacement and pressure integrated observation assembly. The experimental device comprises a soil experimental tank and a waist rail tightly fixed on the periphery of the soil experimental tank. The experimental device also comprises the soil horizontal displacement and pressure integrated observation assembly. The device comprises an observation gauge supporting frame fixed on the waist rail through a bolt, an observation gauge fixing frame fixed on the an observation gauge supporting frame through a bolt and an observation gauge assembly fixed on the observation gauge supporting frame through a clip. An experimental mold acquires horizontal displacement and pressure at different sites of the soil so as to prevent distortion of experimental results, by adjusting relative positions of the observation gauge supporting frame, the observation gauge fixing frame and the observation gauge assembly which are fixed on the observation gauge supporting frame. Compared with a conventional experimental device, the experimental device provided by the invention has the advantages of wide observation range, high precision, simple structure, low cost, etc.

Description

technical field [0001] The invention relates to a soil experiment mold, in particular to an experiment device with an integrated observation component for soil horizontal displacement and pressure. Background technique [0002] Model test is one of the basic means of geotechnical engineering research, and soil displacement and horizontal pressure are the two most important observation parameters in model test. Soil displacement is composed of vertical displacement and horizontal displacement. There are many observation devices for vertical displacement of soil, but there is still a lack of effective observation methods for horizontal displacement, especially for observing horizontal displacement inside soil; and for a long time, There is no effective observation method for the displacement and horizontal pressure of any point in the soil, which brings a certain degree of distortion to the test results, and this distortion increases with the increase of displacement and horiz...
