Abstract

The present paper, illustrated the results of numerical investigation and a series of experimental modeling on optimization of pile length in reinforcing earth slopes using piles. In this paper, the length of different piles with various diameters analyzed and the relationship for optimal length proposed. Stabilization of earth slopes and proposing different methods is one of the main issues in geotechnical engineering. Using numerical and analytical methods in stabilization of earth slopes reinforced by piles are common method, which, carried out by lots of researchers. Finding the optimal length of piles in reinforced slopes is an important matter that reduces the expenses and make the project economical.
