Peat is considered one of the most problematic soils in the construction industry due to its poor physical, mechanical, and dynamic properties. It exists in the coastal part of peninsular Malaysia, and covers almost 8% of the country's land. Therefore, building or road foundations on peat in the coastal region are deemed a serious threat to construction engineers. Thus, it's essential to strengthening its weak properties. This study aims to improve the physical, mechanical, and dynamic peat properties, including shear strength, maximum dry density, moisture content, liquid limit, and shear wave velocity. The soil samples were collected from different locations in Parit Botak area, Batu Pahat District, Johor state, Peninsular Malaysia. The electrokinetic stabilization (EKS) method was applied with an operated electric gradient of 150 V through an aluminum electrode on anode and cathode for 6 h. As a result, the change in moisture content, liquid limit, density, and shear wave velocity has indicated that post-treatment stability has been improved. It is, therefore, concluded that the EKS technique is effective and capable of strengthening the properties of soft soil.

在马来西亚半岛的柔佛州,电动稳定(EKS)对其软土(豆)的稳定性及其物理,机械和动态特性产生影响

泥炭由于其不良的物理,机械和动态特性而被认为是建筑业中最成问题的土壤之一。它存在于马来西亚半岛的沿海地区,覆盖了该国近8%的土地。因此,沿海地区泥炭上的建筑或道路基础被认为是对建筑工程师的严重威胁。因此,必须加强其薄弱特性。这项研究旨在改善泥炭的物理,机械和动态特性,包括剪切强度,最大干密度,水分含量,液体极限和剪切波速度。土壤样品是从马来西亚半岛柔佛州Ba株巴辖地区的Parit Botak地区的不同地点收集的。通过阳极和阴极上的铝电极以150 V的工作电梯度施加电动稳定(EKS)方法6小时。结果,水分含量,液体极限,密度和剪切波速度的变化表明后处理稳定性得到了改善。因此,可以得出结论,EKS技术是有效的并且能够增强软土的性能。
