Analysis of Dynamic Pile Load Test Results and Further Its Uses

Static pile load test is costly and time consuming test. Therefore, dynamic pile load test can be considered as alternative test. Limitation of dynamic pile load test is that it cannot identify the actual capacity of the pile and use only for design capacity verification during construction stage not Detailed Design Stage. Therefore, benefit from pile load test is not obtained like reduction of pile length/number of piles in group. Extrapolation method presented in this paper and compared with capacity obtained geotechnical report. Hyperbolic graph has been used for pile capacity. This paper presents preparation of hyperbolic curve for load settlement and its uses for capacity evaluation and separation of skin friction and end bearing. Projected capacity is also compared with one static pile load test near Pier P2 and found satisfactory co-relation. It is found that capacity of piles are increased by about 37 % and factor of safety used capacity analysis can be reduced by in the range of 20-30 %.
