Study of Vertical Variation Regularity of Horizontal Soil Arching Height Along Pile Length

Stabilizing piles are now considered one of the most effective measures of enhancing the stability of landslides, the horizontal soil arching effect has an important influence on the force of the structure between piles. Until now, the variation of the soil arching height along pile length is not considered in practice, and the variation which can affect the force of stabilizing piles and the structures between piles. This paper presents the numerical simulation to analyze the law of the variation of soil arching height along pile length. The results show that (a) the height of the soil arching decreases monotonously along pile length; (b) the position of the soil arching appears above sliding surface and under the pile-top; (c) the soil arching effect cannot be considered under the sliding surface.
