Experimental study of bearing capacity pile foundation on peat soil by properties improvement using electrokinetic method and clamshell

Abstract

Problem always arise when building infrastructure is located on peat soil, such as on a settlement bridge. To know this, an experimental test was conducted. From experimental testing, the PT00 model had the biggest drop at 87.16 mm, for the PT-25V model was 65.30 mm and the PT-KK-25V model amounted to 67.23 mm. For the model of PT00 experienced a faster settlement and small load is 37 kg, model PT-25V can withstand the load up to 49 kg, while for the model PT-KKK-25V, the pile foundation can afford the load up to 204 kg. The peat soil with pile foundation undergoes the fastest decrease of 52.25 mm on the PT-KKK-25V model. For PT00 and PT-25V models subjected to a smaller decrease process of 38.8 mm and 28.78 mm. The results of this analysis can be concluded that for the test pile foundation pressure. The aplication of improvement is more effective on the model PT-KKK-25V, namely pile foundation model is mixed 8% optimum contain of clamshell and electrokinetic with a voltage of 25V. However, for the pile foundation tensile testing, the application of modelling is more effective on the PT-25V type. Because electrokinetic can enlarge the tensile force of the pile foundation.
