Arching Effect of Anti-slide Piles in Non-cohesion Soil

In recent years, Anti-slide pile has been widely used in soil reinforcement works, but the pile soil interaction is not very clear. Numerical simulation was used in this article to analyze the soil arcing effect between anti-slide piles in non-cohesive soil and the main influencing factors, such as soil horizontal pressure, pile spacing and so on were also analyzed. The results show that there has soil arching in non-cohesive soil, and the soil arching effect becomes significantly with the horizontal earth pressure increases, but when the pressure increases to a certain degree, the soil arching will be damaged. The pile spacing is also a major factor to affect the soil arching effect, increases with the pile spacing, the soil arching effect gradually weakened.
