Underground test cell for multiple geotechnical tests

Abstract

The invention discloses an underground test cell for multiple geotechnical tests. The underground test cell comprises an underground test cell main body excavated on the ground, a counter-force deviceI is vertically fixed in the middle of a cell bottom of the underground test cell, the counter-force device I equally divides the underground test slot into two parts; one part is a similar test areaand the other part is a uniaxial and biaxial shear area and s multi-point loading area; a uniaxial pressure supply device cell, a multiaxial pressure supply device cell and a counter-force device IIare arranged in the uniaxial and biaxial shear area and the multi-point loading area; and a jack is arranged in the uniaxial pressure supply device cell and the multiaxial pressure supply device cell.The entire underground test cell disclosed by the invention is underground cell, the ground space cannot be occupied, and the operation is relatively flexible; the cell, the jacks and the steel plateare combined to perform the geo-technical similarity test, the uniaxial and biaxial shear test and multi-point loading test, and the functionality is high.

Description

Technical field [0001] The invention relates to a test tank, in particular to an underground test tank which can be used for various geotechnical tests. Background technique [0002] Geotechnical testing has always been one of the key points of civil engineering tests. Many on-site tests cannot be solved and need to be carried out indoors. This has given birth to many indoor geotechnical testing equipment. The quality of the testing equipment directly affects the test results, which is particularly important. Model testing has always been the most commonly used means to solve complex engineering problems. In engineering problem research, the use of similar model tests can reduce the parameters described in the problem and the geometric size of the model test is generally much smaller than the prototype. Therefore, the model is easy to make, saving materials and time, and the same model can be used for multiple different parameters. test. Because the test model is small, the tes...

Problems solved by technology

At present, most of the geotechnical test equipment is relatively bulky, occupies a large area, has a single function, and is expensive. Therefore, it is particularly important to improve the functionality of the test equipment.
