In this study, the performance of the stone column encased with conductive jute geotextile in improving the characteristics of soft clay under k₀ stress condition was evaluated using a custom-designed large-scale consolidation test setup. The electrokinetic-encased stone column (e-ESC) was designed as a cathode, while mild steel rods were chosen as anodes, and by applying a voltage gradient of 0.1 V/mm between the electrodes, electrokinetic processes were initiated. The efficacy of using the e-ESC in improving the performance of soft clay was assessed by comparing the results with an ordinary stone column (OSC) and encased stone column (ESC) reinforced soft clay. The results from the study reveal that the inclusion of stiffer material like OSC and ESC in soft clay has significantly increased undrained shear strength and modulus of subgrade reaction of the composite ground with a reduction in settlement and compression index. Due to the application of the voltage gradient between the electrodes, the rate of consolidation settlement of composite ground has significantly increased when compared to the OSC/ESC case. Further, it was confirmed from the chemical and mineralogical analysis that the pH, chemical composition, mineral phases, and microfabric of soft clay were altered with the voltage gradient.

在这项研究中，使用定制设计的大型固结试验装置评估了用导电黄麻土工布包裹的石柱在 k ₀应力条件下改善软粘土特性的性能。电动包裹石柱 ( e- ESC) 被设计为阴极，而低碳钢棒被选择为阳极，并通过在电极之间施加 0.1 V/mm 的电压梯度，启动电动过程。使用e的功效通过将结果与普通石柱 (OSC) 和包裹石柱 (ESC) 增强软粘土进行比较，评估了 ESC 在改善软粘土性能方面的效果。研究结果表明，在软粘土中加入更硬的材料，如 OSC 和 ESC，显着提高了复合地基的不排水剪切强度和路基反应模量，同时降低了沉降和压缩指数。由于在电极之间施加了电压梯度，与 OSC/ESC 情况相比，复合地面的固结沉降率显着增加。此外，化学和矿物学分析证实，软粘土的 pH 值、化学成分、矿物相和微结构随电压梯度而变化。
