Abstract:
In India, the energy demand is anticipated to grow in the next few decades. The government of India is in the process of revamping of the existing refineries as well as the establishment of new refineries across the country in order to meet the energy demands. Most of the refineries in India are located along the coastal region because of the ease of transport of crude material. Considering the criticality of the structures as well as soil conditions in the coastal region, pile foundations are commonly used in refinery plants. In India, non-displacement piles in the form of bored cast-in-situ piles are commonly used to support the structures. In few circumstances, displacement piles in the form of driven cast-in -situ piles are also being used to support the critical structures. This study presents the performance of non-displacement and displacement piles for similar ground conditions at the same location. The test results have shown that the settlement observed for displacement piles is lesser compared to non-displacement piles for a given loading and soil conditions. This shows that performance of displacement piles is superior to the performance of non-displacement piles.
