“…Meanwhile, Vakilian (1978) defined lithosols as type of soil suitable for growing crops with adequate rainfall. Hadi et al (2020) indicated that the surface of Cameron Highlands was made up of residual soil consisted of clay. 2020) described clay as a binder in maintaining the structure of residual soil.…”

“…Excessive infiltration due to intense rainfall would lead clay particle in soil structure to swell, resulted in slope failure. A graph of Soil Water Characteristic Curve (SWCC) for granitic residual soil VI by Hadi et al (2020) in Figure 4 was reviewed following to this phenomenon. Water content was referred as the amount of water contained in soil, measured in percentage (%).…”

Cases of landslides occurrences in the time of intense rainfall were reported throughout the years especially at Highlands in Peninsular Malaysia. Infiltration of rainwater caused various moisture content in soil of slope resulted in these landslides. Thus, this study was performed to evaluate the moisture content of residual soil on slope at Kampung Raja, Cameron Highlands. The objectives were to collect and label the soil samples, analyze the moisture content in laboratory, then evaluate them with an existing model. Soil samples were collected at 10 different locations by digging between 0.2 to 0.5 meters deep, placing the soil into plastic containers, and weight them. The containers were labelled with individual number sequence, weight, date, and time of sampling. The coordinates and surrounding temperatures of each samples were also recorded by utilizing software in smartphone i.e., Google Maps and Weather application. By referring to BS 1337: Part 2: 1990, the determination of moisture content was performed using oven-drying method in laboratory. The soil located on a slope at Kampung Raja, Cameron Highlands had moisture content between 24.1% to 38.5% with an average of 27.6%. The results were evaluated with Soil Water Characteristic Curve and was found that the soil had potential risk for future landslide. The results of this study could be used to correlate with the water suction property of the soil.

The strength aspect of clay soil is a critical concern in practical engineering design. Electroosmosis (EO) has been adopted as a foundation treatment technology in some projects to increase the strength of soft clay. In order to widen the understanding on shear strength performance of EO-treated soil, the behavior of EO-treated soft clay using electrokinetic geosynthetics (EKG) as electrodes under the effect of water immersion was evaluated and compared with that of vacuum preloading (VP) treated soft clay under similar conditions. The main finding was that the EO-treated soil when immersed in water offered more resistance to the change in average water content than VP-treated soil. The average shear strength of EO-treated soil fell by 36.6% during 4 extra days of immersion. When the immersion time was extended to 10 days, the average shear strength fell by 65.4%. In contrast, the immersion time had little influence on the shear strength of VP-treated soil. Hence, if EO-treated soft clays are to be subjected to short-term water immersion, the shear strength of the treated foundations should be reappraised to ensure the safety of the engineering projects.
