【 摘 要 】

The deep foundation at the Ketek Sikara-kara wharf is the function of foundation that distribute the load from the upper structure of the building to the soil on the bottom of building to the hard soil layer, without effecting shear failure and settlement, has a bearing capacity allowed. The function of Pile Driving Analyzer (PDA) at Parlimbungan Ketek Sikara-kara wharf to determine the bearing capacity of pile and also control to calendering test result, then this researched were tested the pile driving analyzer at 8 sections of pile from 84 sections of calendering pile (10% of the number of sections setting up). Obtained calendering results of lowering is equal to 0.60, 071, 045, 060, 053, 041, 065, 060 fulfilled the specification allowed ≤ 1 inch (2.54 cm). The largest value of pile calendering bearing capacity is 128.52 Ton and the smallest bearing capacity is 73.29 Ton more larger than the allowable pile bearing capacity is 60.9 Ton. Pile driving analyzer results of the largest bearing capacity is equal to TP - B12 Ru 177 Ton more larger than the bearing capacity of pile is allowed on planning is 60.9 Ton and the smallest is equal to TP - B22 Ru 111 Ton more larger than the bearing capacity of pile is allowed on planning is 60.9 Ton.
