| Summary: | Bearing capacity of pile group in cohesionless soil is an interesting topic with studies about coefficient of efficiency, about critical depth where skin friction seems constant with respect to depth of embedment/installation etc. This article focuses on bearing capacity of pile group with variety ofconfiguration with numbersof piles in group, and with pile center-to-center distance. Single pile and pile group in non-cohesive nearly homogenous soil foundation was modelled using Plaxis 3D. Result indicates that pile group capacity varies as the distance or number of piles changes, not only decreases as the number of piles increases; besides, efficiency depends on a) considering various number of piles with the same center-to-center distance, or b) considering as same number but at different pile distances. Discussion then suggests a reasonable configuration for pile group in non-cohesive soil foundation. |
