Helical Pile Subjected to Vertical Loading: Theoretical Study

The use of pile foundation is increasing day-by-day due to non-availability of suitable land for construction. Heavy multi-storyed buildings are being constructed, and load from these structures cannot be directly transferred to ground due to low bearing capacity and stability issues of the buildings. So, demand for use of pile foundations are increasing day by day. Due to this demand of pile foundations, there have been many improvements in pile foundation technology. Helical pile is a newly developed structural foundation member used to transfer the vertical loads coming on the structure. This paper present a detailed investigation of helical pile subjected to vertical loading. Two piles made up of steel and concrete, are being tested using a field setup. The helical pile used, were having three helix plates and the concrete pile was casted in the same trench made by steel pile, and tested after 28 days. The results of the field load test were compared with theoretical solutions using conventional theories.
