Research on the Lateral Pressure Coefficient and Depth of the Load-bearing Arching between Cantilever Piles

摘要

It is concluded that the axis of the load-bearing arching is catenary through theoretical analysis in this paper, according to the principal stress deflection of soil, it is concluded that the lateral pressure coefficient of the load-bearing arching is different the other place of soil, based on the single shear limit equilibrium of soil, the buried depth of arch foot is known, and its relationship with height of cantilever piles section is analyzed, the analysis results show that the lateral pressure coefficient of the arch decreases with the increase of the internal friction angle of soil, the strength coefficient of the arch increases with the increase of the internal friction angle of soil, height of cantilever piles section have less effect on the buried depth of arch foot, the influence of height changes can be ignored to the thickness of arch, when the soil is certain.
