Liquefied landslide disasters induced by earthquake are serious

in order to solve the problem of support and management of slopes with liquefiable soil layer

a novel anti-slide pile to prevent liquefaction is proposed based on the concept of "combination of prevention and resistance"

which integrates active drainage and passive anti-slip. To evaluate the effectiveness of the novel anti-slide pile in preventing liquefaction

a slope model was developed based on survey data from slopes with liquefiable soil layers in the upper Yellow River region. A large-scale shaking table model test was conducted to compare the novel anti-slide pile with conventional ones. The failure mode and dynamic response characteristics of excess pore water pressure in soil of the slope with liquefiable soil layer supported by different types of anti-slide piles under earthquake are obtained. The results indicate that the failure mode of slope with liquefied soil layer supported by anti-slide pile under earthquake is earthquake-induced-horizontal ejection of overlying soil layer on liquefied soil layer-bulging

shearing of slope surface at the bottom of liquefied soil layer-flowing and sliding accumulation of soil in front of anti-slide pile. In comparison to conventional anti-slide piles

the novel anti-slide pile for liquefaction prevention can rapidly and efficiently dissipate excess pore pressure in the surrounding soil. This mechanism effectively prevents liquefaction around the pile

achieving the goal of liquefaction prevention. The research findings confirm the reliability of the novel anti-slide pile for liquefaction prevention

providing valuable insights for mitigating seismic liquefaction landslide disasters.
