Abstract
Bangladesh is a low-lying country crisscrossed by many rivers. Large diameter bored piles are replacing caisson foundation in Bangladesh. Bored cast in situ pile is a popular choice for heavy loaded structures due to the ability to adjust the pile length suitably in case of any variation found in the actual geological strata. Geological strata are predominantly silt in nature and N-value in this region is less than 5 up to 15 m depth. Pile design is based on field N-values and laboratory test results. Pile capacities estimated through static formula are in co-relation of N-value and laboratory test results. Two 1.5 m diameter bored cast in situ piles without base grout and two 1.5 m diameter bored cast in situ piles with base grout were casted, and initial load test was performed on these piles to finalize the pile length. This paper presents the vertical load performance of 1.5 m diameter base grouted concrete piles in comparison with ungrouted bored piles.
