Abstract

Electrokinetics is one of soft ground improvement methods to improve its bearing capacity. The objective of this research is to investigate the increase of friction and end bearing resistance of an embedded instrumented model pile in marine clay after electrokinetics treatment. The initial geotechnical properties of soil surrounding the pile foundation is obtained by several soil laboratory tests. For pile bearing capacity analysis, friction and end bearing resistance of pile was measured by load cell measuring device, while un-drained shear strength analysis was measured by vane shear test. The result of this research showed that after 24 hours electrokinetics treatment, the un-drained shear strength increased closer to the pile, and the bearing capacity of pile increased 14 times. Abstract in Bahasa Indonesia : Elektrokinetik adalah salah satu metode perbaikan tanah lunak yang diaplikasikan untuk meningkatkan daya dukung tanah lunak. Tujuan dari penelitian ini adalah untuk menyelidiki peningkatan tahanan friksi dan ujung suatu model pondasi tiang di lempung marina setelah dilakukan proses elektrokinetik. Karakteristik tanah pada kondisi mula-mula di sekitar pondasi tiang didapatkan dari beberapa pengujian di laboratorium. Untuk analisa daya dukung tiang, tahanan friksi dan ujung dari pondasi tiang diukur dengan alat pengukur load cell, sedangkan analisa kuat geser undrained diukur dengan pengujian baling-baling. Hasil penelitian menunjukkan bahwa setelah pada tanah dilakukan proses elektrokinetik selama 24 jam, daya dukung dari pondasi tiang meningkat 14 kali dan semakin dekat dengan tiang, kuat geser undrained juga semakin meningkat.

Abstract

The high water content in marine clays could loosen the bond of soil particles, resulting in low bearing capacity and high compressibility of the soil. Excessive settlements could happened to the structures built on it. An electrokinetic process was attempted to reduce the high water content of the marine clay. An experimental study was conducted to evaluate the effect of electrokinetic on marine clay improvement. This study focused on the use of electrokinetic to enhance the soil bearing capacity of marine clay by improving index properties of the marine clay. The result of this research was obtained by doing several analyses on water content, pH value, and soil particles of soil sample located between cathode and anode. Based on the results from laboratory testing, it can be concluded that electrokinetic process decreased the water content and pH value of soil surrounding the anode. Also, soil particles surrounding the anode became in close proximity. This indicated that as it became closer to the anode, soil became denser.
