Centrifuge Model Test of Earthquake Countermeasures for Deposit-on-Slope

    Abstract
  • Based on the pseudo-static method,the reinforcement measures of anti-slide piles and their combination with anchor bolt frames were investigated with centrifuge model tests and numerical simulation in order to probe into the failure mechanism of deposit-on-slope reinforcement under an earthquake.The experimental results show that overtopping collapse possibly occurs when only anti-slide piles are used to reinforce the bottom of deposit-on-slope.Anti-slide piles combining with anchor bolt frames can improve the distributions of stresses and strains in deposit-on-slope,and decrease its deformation and force acting on anti-slide piles greatly.Based on the above results,it is suggested that the principle of "slope bottom reinforcement and mountainside strengthening" should be emphasized in the design of deposit-onslope in high earthquake intensity regions.
