Description
Technical Field
The invention belongs to the field of rock-soil test instruments, and particularly relates to a test device for a pseudo-static rock-soil model.
Background
The low-cycle reciprocating load test is a static test for applying repeated cyclic reciprocating loads to a structural member or a model, is a repeated loading and unloading process of the structural member or the model in the positive and negative directions and is used for simulating the stress characteristics and the deformation characteristics of the structure in reciprocating vibration during earthquake. The method is used for solving the effect of structural vibration by using a static method, so the method is called pseudo-static test or pseudo-static test, but the conventional rock-soil test model box is often single in test and research, most devices for performing the pseudo-static test are complex in operation, and various test conditions of a test object, particularly the application of combined load and the control of the test conditions, including boundary condition control and the like, are difficult to meet. The method has great limitation on the study of the seismic performance of the structure, and is an important problem in the current study.
Geotechnical engineering tests are a generic term for testing various rocks and soils for engineering and construction purposes. Geotechnical tests are an important component of engineering geological investigation. It is divided into sampling test for taking out rock and soil samples from stratum and in-situ test directly on rock and soil. However, in-situ tests are sometimes impossible due to limitations of field conditions or mechanical equipment, and most in-situ tests are conducted on a single test object at a specific site, so that it is difficult to conduct systematic studies on the test object.
Pile foundations are an important form of foundation that functions to penetrate through weak and highly compressed earth or water to transfer the pile load onto a harder, denser or less compressed bearing layer. We generally refer to the piles in the pile foundation as foundation piles. The pile foundation test is also called pile foundation detection: and determining whether the pile foundation engineering meets the design requirements or not by testing and evaluating the bearing capacity of the pile foundation and the quality of the pile body.
The slope stability refers to the stability degree of the rock and soil bodies of the slope under the conditions of certain slope height and slope angle. Because the factors influencing the deformation and the damage of the side slope are very complex, the simulation test of the side slope is more and more emphasized by scholars, so the side slope test model box convenient for controlling the test conditions has practical significance for researching the mechanism of the deformation and the damage of the side slope and understanding the deformation and the damage process of the side slope under the action of gravity.
