Bored Pile Designs Using Geotechnical Data in Parts of Port Harcourt and Environs, Rivers State, Nigeria

Abstract

Assessment of ultimate pile carrying capacity (deep foundation) and its settlement in parts of Port Harcourt and environs Rivers State has become imperative due to moderate bearing pressure and poor subsoil nature found in the study area. Bored pile foundation analysis was carried out for the soil profiles with diameter 306, 406, 460 and 600mm for the deep foundation at various study area were calculated. The study shows that the higher the diameter and pile depth of the foundation, the higher the ultimate pile carrying capacity. The settlement of the piles fall within an acceptable criterion of one-tenth. Safe working load of Greater Port Harcourt New Stadium Precient (BH4) was found higher, when compared to other locations in parts of Port Harcourt and environs.
