| Abstract | ||
| This paper investigates numerically, the effect of a buried rock under strip footing resting on sand. This buried rock can be a part of an old footing or rock that was embedded without any knowledge about its location. In this study, the effect of the buried rock on contact stresses, under the strip footing is analyzed using finite element technique. The rock is proposed to have a cross section of 0.5x0.5 m continuously under the strip footing. The effect of rock position and depth is analyzed under the strip footing. The final results showed that the stresses under the strip footing have increased by 40%, when rock is encountered under the middle of the footing at depth D=0.5m. Moreover, the analyses showed that the stresses under footing had altered when the buried rock lies away from middle footing reaching to the instability of the footing. | ||
