Efficiency of Pile Foundation in the Construction of Basement Floors of Structures on Collapsible Soil

This study discusses the issues in increasing the reliability of buildings and structures on Type II loess-like collapsible soils through the construction of basement floors. This study also analyses the effectiveness of using pile foundation options for buildings with basement floors made from driven and bored piles up to 50 m long that cut through collapsible soil of 10–32 m. Results showed that foundations made of driven and augered piles are the most effective in terms of cost, labour intensiveness, and concrete consumption, whereas options using barrettes are the least effective.
