FEM Analysis on Slope Step Reinforcement Micro-Pile

Abstract:

Micro-pile of slope reinforcement type is more and more used in slope engineering, at the present stage most of the projects are designed by engineer experiences, theory researches are hysteretic, load transfer and mechanics characters are not clear. Combining with Heshun highway Slope treatment project, this micro-pile structure are analyzed with finite element method (FEM) under different conditions like different anchorage depths, pile diameters and displacements on the pile roof. Under these conditions the strain and stress are calculated, the results shows that: there is an optimal anchorage depth, under this depth the concrete can produce the best properties and save funds; increase the diameter will improve bearing capacity observably; the displacement of pile roof can also can be decreased if increase the modulus of elasticity.
