Abstract

The invention discloses an air cushion suspension type rock-soil centrifugal machine. The centrifugal machine comprises a model test cabin which is located under the ground and movably arranged in a vehicle body of a suspension structure, a linear motor, data acquisition equipment, wireless transmission equipment, power supply equipment and a ground laboratory computer; two parallel first air cushions are arranged on the side portion of the vehicle body of the air cushion suspension structure in a spaced mode, and two parallel second air cushions are arranged at the bottom of the vehicle body of the air cushion suspension structure in a spaced mode; a gap formed between the two first air cushions is connected with a first rail in a matched mode, and a gap formed between the two second air cushions is connected with a second rail in a matched mode; a stator of the linear motor is fixed to the first rail and the second rail, and a rotor of the linear motor is fixed to the vehicle body of the suspension structure; and the data acquisition equipment is arranged in the model test cabin and is in signal connection with the ground laboratory computer through the wireless transmission equipment.

Description

technical field [0001] The invention belongs to the technical field of rock-soil centrifugal model tests, and in particular relates to an air cushion suspension type rock-soil centrifuge. Background technique [0002] Since the 1960s, the geotechnical centrifuge has gradually become a cutting-edge test technology in the field of civil engineering in the world. Its main function is to simulate the gravity of the earth in the laboratory, so as to study the deformation of tall civil buildings. and stability issues. Therefore, from the very beginning, geotechnical centrifuge model test technology is an important method to study geotechnical problems. In the test, the reduced-sized structural model was placed in a high-speed rotating centrifuge, and the model was subjected to centrifugal acceleration greater than the acceleration of gravity to compensate for the loss of self-weight of the rock and soil structure caused by the scale of the model, so that the stress in the model a...
