An underground test tank that can be used for various geotechnical tests

Abstract

The invention discloses an underground test tank that can be used for various geotechnical tests. It includes an underground test tank main body dug on the ground. A reaction force device I is vertically fixed in the middle of the bottom of the underground test tank. The force device I divides the underground test tank into two parts, one part is a similar test area, and the other part is a single and biaxial shear area and a multi-point loading area; in the single and biaxial shear area and multi-point loading area It is equipped with a single-axis pressure supply device slot, a multi-axis pressure supply device slot and a reaction force device II. Jacks are installed in both the single-axis pressure supply device slot and the multi-axis pressure supply device slot. The invention is an underground trench as a whole, which does not take up space on the ground and is relatively flexible. By combining trenching, jacks and steel plates, geotechnical similarity tests, single and biaxial shear tests and multi-point loading tests can be carried out, 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 soil engineering tests. Background technique [0002] Geotechnical testing has always been one of the key points of civil engineering testing. Many on-site tests cannot be solved indoors, and many indoor geotechnical testing equipment have been born. 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 the research of engineering problems, the use of similar model tests can reduce the parameters of the problem description and the geometric size of the model tests is generally much smaller than that of the prototype, so the model is easy to make, saves materials and time, and the same model can be used for multiple different parameters. test. Because the test model is small, it can generally b...

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.
