Sixteen different shaking table tests on unreinforced and reinforced soil slope models were performed in this study. These tests are devised to understand the effect of reinforcement parameters on acceleration, frequency of base shaking and reinforcement on the response of the slope during seismic excitation.

2.1. Introduction of the Shaking Table Tests. One-sided rock slopes, two-sided rock slopes and four-sided rock slopes are adopted in this shaking table test to clarify the influence of the type of slope surface on acceleration.
In this research large-scale shaking table model tests were conducted to study slope behavior under earthquake conditions. The model slope was installed into a model box with a length of 4.4 m .
Deck horizontal slope/grade is used for the final control of the concentrate line and for accurate splitting of the concentrate. A slope T handle adjusting screw on the RP-4 and an automatic leveler on the RP-4 is located at the concentrate end of the table.
The results clearly demonstrate advantage of a nailed slope over unreinforced slope. The failure surfaces observed in the shaking table tests are shallow and of rotational type.
A Gold Shaking Table are basically low-capacity machines used as last step in the gold upgrading process. The shaking table is a thin film, shear flow process equipment, that separates particle grains of its feed material based on the differences in their specific gravity, density, size and shape.
A very important operating variable of a shaking table is the tilt adjustment. Normally, the feed side is lower, and the concentrate end is higher on the table, which creates an upward slope where the heavy material will ascend, while the light density material will not, and consequently, flow over the riffles.
Shaking table. The shaking table tests were carried out in the Key Laboratory of Loess Earthquake Engineering, Gansu Earthquake Administration in China. A large-scale two-directional (horizontal and vertical) electric servo shaking table was employed for the tests.
The model slope, nearly intact under 500 Gal shaking, suddenly developed cracks and then slid at shallow depth below the slope under 700 Gal shaking. In the same figure, the time histories of horizontal acceleration along the slope surface are shown.
