The Improvement on the Determining Method of the Proper Pile Length in the Collapse Loess

Abstract:

In Consideration of the nonlinear of the soil and the interface between pile and soil, the spatial axisymmetry finite element model is established. Based on the model, the paper offers the Superposition Method to calculate proper pile length in the self-weight collapse loess , and gets the following deduction: when the upper and lower parts of soils skin friction has the same regularity, added pile length L has nothing to do with the skin friction distribution, but is related to ultimate friction resistance. Practical application shows that the method is effective and can be referenced in engineering practice.
