| چکیده | ||
| The present paper reveals the results of an analytical method to calculate the bearing capacity of a footing supported on one or two rows of piles stabilizing slope. The varied parameters here include pile diameter, pile length, location of pile rows, location of footing relative to the slope crest, foundation width, center to center spacing of piles in a row, and fixity of the pile head. Passive pile resistance is determined based on normal and shear resistance of the soil surrounding the pile considering plastic deformation of soil between piles. The Pile resistance obtained through the present method is compared with other analytical as well as 3D numerical ones. The results indicate acceptable agreement. The footing bearing capacity is calculated according to both the limit equilibrium slope stability analysis and soil stability beneath the footing. The predicted results were compared with those reported from other experiments and indicated an acceptable agreement with increasing pile spacing. The results indicate that stabilizing the earth slope with rows of piles has a significant effect on the footing of bearing capacity improvement. | ||
