| Abstract | ||||
| This study is concerned with identifying the behavior of contiguous pile groups subjected to vertical load, and the corresponding soil failure. A wide range of geometrical parameters were represented in order to investigate the effect of these parameters on the behavior of the pile group including spacing between piles and number of piles in group. To study the effect of length, the piles used in laboratory tests were 3 cm in diameter and 30 cm in length. D to 2D spacing between piles were also adopted. The sand used in the experimental program had two different densities. The scope of research includes tests on vertical loaded contiguous pile groups in sand. The tests were executed in a wide tank containing the sand as well as models of pile groups. Using the experimental model results, relations were utilized to estimate the bearing capacity of the pile group. From the test results it was found that increasing the spacing between piles and number of piles in a group < br />causes increase of the bearing capacity of the pile group. | ||||
