Abstract

Rapid foundation should be movable, low weight and high strength to be used in critical situations. In this study, steel foundation is discussed due to high ductile and strength. Thus, steel plate and pile system is evaluated by plaxis 3d foundation and parameters of length (L), number of steel piles (N), thickness (t) and dimensions of plate (B) are studied. The Mohr Coulomb was used to model soil behavior and steel piles and plates in dimension of 200, 300 and 500 mm were evaluated. The results show that area ratio of pile to plate (AS) is affected by bearing capacity and settlement reducing. In this study, while the area ratio of pile to plate is more than 5%, the bearing capacity ratio (BPI) has increased with increasing length, diameter and number of piles. Whereas, the BPI of plate in dimension of 200*200 mm and 500*500 mm in single pile mode to four pile mode ratio is increased from 1.01 to 1. 8 and 1.01 to 1.15, respectively.
