Analysis of the behaviour of the floating pipe pile foundation on soft soil

Abstract

Planning the foundation according to the characteristics of the soil is the most important thing before starting construction. In recent studies, the use of PVC pipe pile foundations has been introduced. These foundations, called floating foundations, offer a lighter and more economical solution for simple buildings on soft soils. The study involved variations in pipe diameters of consistent lengths. In laboratoryscale axial loading tests, the behaviour of pipe stacks against load drop is observed. The bearing capacity of pipe piles is evaluated through a static loading test, with one end of the pipe pile hermetically sealed and aspirated in an alternating pile in a glass box filled with soft soil with a content of 98%. The results of this test are then analyzed with the Chin Method Interpretation to determine the carrying capacity and behaviour of pipe piles against soft soil, The results of the analysis show that the diameter of the pipe piles has a significant effect on the bearing capacity of the foundation. Although the results are promising, further research is still needed, especially in the development of foundation construction suitable for multi-storey buildings in areas with soft soil or peat
