PENGARUH WAKTU TERHADAP PENINGKATAN KAPASITAS DUKUNG KELOMPOK TIANG PADA TANAH LUNAK

Abstract

Tests by previous researchers have discovered phenomenon increasing significantly of axial capacity foundation on soft soil. In this final project researchers created a model of the group piles in soft soil and given time variations of pile driving. By keeping the soil moisture conditions in order to condition the soil shear strength does not change, it is hoped the results of this study demonstrate and produce an increase in the amount of the axial bearing capacity of pile. The results of direct testing and interpretation of the results showed a significant increase until the end of the age of Pile Driving (68 days). At the age of 68 days, the pile axial capacity increased by an average 50.2% of the age of piling on one day. The study also produced an increase in the time factor (Δ10) that can be used in the empirical formula found by previous researchers.
