During the design of multi-row and embedded anti-slide piles of large landslide

the most important thing which most designers are concerned about is the landslide thrust of each row of piles and the distribution mode along the pile when the row distance or embedded depth is different. It’s difficult to study all kinds of large landslides

so a typical landslide with polygonal line slip surface is studied. And in order to simplify the analysis

it’s assumed that it has specific landslide surface. Based on indoor model test

the general law about landslide thrust of each row of piles with different row distances is obtained. Also by the strength reduction finite elements

the distribution mode of landslide thrust along the pile with different embedded depths is analyzed. The result that the change of row distance or embedded depth is a proper method for optimizing the ratio of each row of piles is presented; and the landslide thrust distribution law of row of piles is a guidance for the civil engineering designers to accomplish more reasonable design of multi-row and embedded anti-slide piles in reinforcing large landslides.
