Description
Technical Field
The invention relates to a slope dynamic response experimental device and method for simulating the oblique incidence effect of seismic waves.
Background
In recent years, in China, earthquakes frequently occur, which induce hundreds of thousands of disasters such as landslide and collapse, and cause loss of lives and properties of people. The dynamic response characteristics and the failure mode of the side slope under the action of seismic waves are mastered, and a theoretical basis can be provided for side slope disaster prevention and side slope management.
At present, an experimental device and method for simulating dynamic response under the action of a slope earthquake are mainly a vibration table method. A vibration table is a device that uses electric, electro-hydraulic, piezoelectric or other principles to obtain mechanical vibrations. The principle is to input an excitation signal to a coil placed in a magnetic field to drive a stage connected to the coil. The vibrating table can effectively simulate the dynamic response of a building (structure) under the action of an earthquake, but has the following problems in the aspect of slope dynamic response simulation: firstly, most seismic waves adopt a vertical incidence input mode, and the oblique incidence input mode of the seismic waves is difficult to realize; secondly, according to the similarity ratio theory, in the slope dynamic response physical simulation, the geometric similarity ratio and the wavelength similarity ratio should be equal, so that the similarity of the model and the physical law in the original shape of the slope can be realized. In addition, because the vibration table can not input high-frequency earthquake waves, the similarity ratio of the wavelengths in the high slope simulation is difficult to meet the requirements, so that the vibration table can only simulate a low slope and can not simulate the earthquake dynamic response of the high slope; and the simulation cost of the vibration table is higher.
