Shaking table tests on geosynthetic-reinforced slopes- Effects of reinforcement configurations

Abstract

The present study used a geosynthetic-reinforced slope model with different length of reinforcement and a number of the reinforcement layer A laminar box was used which contain the model during the shaking table tests The soil used in this experiment is the middle and upper reaches of Meixi in Nantou County The different test was done on the model and the results are compared with test results reported in the literature: 1 The maximum permanent displacement of the slope(D_max) under various horizontal peak ground acceleration(HPGA) shows that 5layer 0 7H performs better than 3layer 0 7H and 5layer 0 5H 2 The normalized displacement curves obtained here show that that before the surface acceleration exceeds the limit acceleration a_y the wall has been displaced and empirical curves reported in the literature suggesting that a permanent displacement of the slope could not happen if HPGA is not greater than a_y 3 In this study the acceleration amplification factor shows the same trend as the other researchers 4 From arias intensity and a_rms it can be seen that 5layer 0 7H required more energy for failure than the other models 5 Stiffness coefficient and Internal failure index are good indicators that can be utilized to evaluate the seismic response of reinforced slopes
