摘要:

Shaking table model test is an important means to study soil-underground structure dynamic interaction under earthquake. The property of soil filled model box directly affects the correctness of test results. Here, based on the basic principle of structural dynamics, a laminar shear model box with adjustable spring and damping was designed, and its effectiveness was verified with shaking table tests. Meanwhile, the dynamic performance of the model box was analyzed with the software ANSYS. The test and analysis results showed that the designed laminar shear model box with adjustable spring and damping has a good effect to simulate actual site with infinite boundary condition, and reflect a soil-underground structure interaction system's dynamic response feature of being controlled by speed and displacement; the performance of model box can be adjusted according to type of model soil to meet test's requirement of reducing model box boundary effect; the developed laminar shear box can provide a new idea for selection of test box in other geotechnical seismic engineering problems. © 2020, Editorial Office of Journal of Vibration and Shock.
