Soil body tester based on soil body elasticity test and test method thereof

Abstract

The invention discloses a soil body tester based on a soil body elasticity test and a test method thereof, the soil body tester comprises: a measurement cabin used for placing a test sample soil block, wherein the measurement cabin is a sealed cavity, and an extrusion device used for extruding the sample soil block is arranged in the measurement cabin; an elastic monitoring system which comprises a detection component which is connected to the sample soil block and is used for monitoring the elastic modulus of the sample soil block in real time when the sample soil block is extruded; and a humidity generating device which is arranged outside the testing bin, is communicated with the testing bin, can input dry gas or wet gas into the measuring bin and is used for changing the temperature or humidity in the measuring bin, so that the body structure of the sample soil block has consistent change with the temperature or humidity in the measuring bin. The tester can be widely applied to the technical field of geotechnical engineering.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering. More specifically, the present invention relates to a soil testing instrument based on soil elasticity testing and a testing method thereof. Background technique [0002] With the rapid improvement of advanced test equipment and the development of computer programming languages, people pay more and more attention to the elastic behavior of soil. The elastic modulus of soil is one of the important indicators reflecting the strength of soil. The change of elastic modulus reflects the internal The elastic modulus is the necessary mechanical property index of the soil when the elastic-plastic constitutive model is used to calculate the stress and strain of the soil. However, since the soil itself is a multi-phase heterogeneous body, the elastic modulus of the soil is easily affected by the surrounding environment of the test, for example: the moisture in the air affects the moisture...

Problems solved by technology

[0003] In the traditional method and instrument, the measurement method is too complicated, the measurement current uses a single-arm bridge with low sensitivity and no temperature compensation function, and the accuracy of the galvanometer is not high, which will seriously affect the accuracy of the measurement results

Therefore, in the prior art, there is a lack of a mini
