摘要：Helical piles foundation systems have been extensively used in engineering application. Helical pilefoundation system are commonly adapted to resists the compression, uplift force, overturning moment and lateralforces. Now a day, helical pile foundation systems have become commonly adapted in many countries. The use ofhelical piles as a deep foundation option has considerably increased in the recent years to support variety of loads, fromsmall loads for several applications such as residential housing, solar farms, and utilities and retrofit projects, to largeloads for many applications such as commercial, power transmissions lines, oil facilities and industrial applications.Therefore, it is necessary to know the axial compression capacities of these piles under vertical loads, for this reasonthe aim of the work is to study how to improve the compressive capacities of helical pile in black cotton soil.Model steel piles with and without helical plate are embedded in black cotton soil are tested to study the effectof vertical loading on the behavior of piles in compression. Laboratory experiments were conducted on the pile of20mm diameter with and without helical plate and with varying helical plate diameters as 25mm, 45mm and 65mmrespectively.
