The location of sliding plane in the model was consistent with the location of the maximum horizontal acceleration. The present study is focused towards under- standing the difference in the seismic response of soil slope with geotextile and.horizontal slope for shaking table,horizontal slope for shaking table,PARAMETRIC ANALYSIS OF HORIZONTAL ACCELERATION .Nov 24, 2017 . A shaking table test on two rock slopes was carried out in the present study. The recorded Wenchuan earthquake waves were scaled to excite the model slopes. Based on the measurements from accelerometers installed on free surface of the model slopes, horizontal acceleration responses were analyzed.
Shaking table tests and stability analysis of steep nailed slopes .Abstract. Shaking table tests were performed on five model slopes to examine the effects of the angle and length of the nails and the frequency of excitation on the seismic resistance and failure mechanism of the slopes. . The slope at an angle of 90° to the horizontal has a markedly lower seismic resistance than that at 80°.horizontal slope for shaking table,horizontal slope for shaking table,Shaking table studies on geosynthetic reinforced soil slopes - Taylor .the effect of the slope angle and reinforcement type is studied by carrying out shaking table tests on models of soil slopes in the shaking table and also by simulating them in a numerical model. Shaking table. A computer controlled servo hydraulic single axis shaking table was used to simulate the horizontal shaking action.John Frank
Each of the clayey slope models deformed in response to strong shaking, with the principal mode of deformation being deep rotational/translational sliding displacement. Deformations were principally focused along one or more highly localized shear surfaces, though a significant amount of additional deformation was also.
of the model slopes are monitored during the tests. 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. The nails oriented in horizontal direction are found to be more efficient. The nail forces and.

May 25, 2015 . ABSTRACT: An understanding of the vertical acceleration response of geosynthetic-reinforced slopes subjected to horizontal input ground excitations is essential to robust seismic design. A series of stepwise intensified shaking tests was performed using simple sinusoidal waves with various horizontal.
In this paper, we report the results of a series of shaking table tests that were used to evaluate the dynamic behavior of rock slope models with various slope inclinations under a given gravitational condition. For simplicity, only the horizontal seismic motion was considered in the slope model used for the investigation.

In the shake table tests, it indicates that under low acceleration (<0.2 g), that the horizontal acceleration on the slope surface increased over 1.5 times.
Horizontal slope of table will change by adjusting the slope tilting screw up or down for precise control of concentrate line. Occasional apply lubricant to threads. rp-4-gold-shaker.

Considering the above disaster phenomena, the reasons are analyzed based on shaking table tests of one-sided, two-sided and four-sided slopes. .. acceleration amplitude in the slope and acceleration amplitude at free field and horizontal acceleration, illustrated as follows: for the one-sided slope model,.
The PEER Earthquake Shaking Table, dedicated in 1972, was the first of its kind and at 20′ x 20′ is still the largest multidirectional shaking table in the US. The shaking table is configured to produce three translational components of motion; vertical and two horizontal, plus three rotational components; pitch, roll and yaw.
Tests were performed on a 2.0 m wide and 2.0 m long shaking table with single degree of freedom. All symmetrical physical models were constructed in a 2.15 m (length) x 1.0 m (width) x 0.76 m (height) container made of steel. Twelve accelerometers were embedded in model slopes to measure horizontal acceleration.
