Abstract
The objective of this paper is to investigate the bearing capacity of strip foundations next to sand slope. A series of laboratory model tests has been carried out and a new correlation coefficient to estimate the bearing capacity of shallow foundations near slopes is presented. The sand layers were prepared in a steel test tank with inside dimensions 500 ´ 200´ 250 mm. After vertical loading, the applied load and displacement of foundation were recorded and stress-settlement curve is drawn. Finally, the load at which the shear failure of the soil occurs is recorded as ultimate bearing capacity of foundation. The test sand used in this study was Babolsar sand with relative density of 50%. The relative performance of different distance of foundation from the edge of slope and inclination angle of slope are compared using same quantity of soil properties in each test. The results indicate that with increasing distance from the edge of the slope, bearing capacity increases linearly. Also with increasing slope angle, the bearing capacity has declined linearly
