Study on the Interaction Mechanism between Micropiles and Soil Landslides

The interaction mechanism between micropiles and soil landslides is comprehensively investigated through static model tests numerical simulations. results show that the deformation damage mode of mainly bending shear damage. Because deformation, cracks appear at rear front pile, respectively, about three times pile diameter from sliding surface. In addition, plastic becomes more severe when approaching back edge landslide body. Micropiles in body play a significant role load sharing; importantly, there certain pattern miniature piles. According to experimental simulation results, recommended load-sharing ratio for micropile design under conditions as follows: rear-row pile:middle-row pile:front-row = 0.411:0.348:0.241. research this paper reveals good effect against landslides, explains pile–soil interaction, provides theoretical reference application engineering.
