The College of Engineering, Diyala University discussed a master dissertation on a laboratory study investigating the effect of osmotic electricity on two-layer soil by the postgraduate student, Ms. Warda Hamoud Majeed.

The dissertation aimed at evaluating the efficiency of electrical arbitration as a method for improving soft clay soils and studying settlement behavior and water movement under the influence of a continuous electric field and analyzing the effect of electrode type, applied voltage, and electrode length on treatment efficiency.

The dissertation included a series of laboratory tests using three types of electrodes (aluminum, copper, and stainless steel) with two different lengths (25 cm and 36 cm), applying voltages of 10, 20, and 30 volts, and comparing the results with an untreated control sample. 

The dissertation reviewed a significant improvement in the performance of electrically treated soil compared to the untreated condition, as well as improvement increased with increasing voltage and electrode length, with the best results recorded using stainless steel electrodes 36 cm long and 30 V, the maximum settlement reached 72.4 mm, representing a 68.3% improvement compared to the control model.

The study demonstrated the potential of electrical arbitration as an effective and rapid method for treating weak clay soils and improving their engineering properties in future geotechnical applications, this contributes to the development of sustainable engineering solutions for addressing foundation and soft soil problems.
