DESIGN AND FABRICATION OF COHESIOMETER APPARATUS FOR SOIL STABILITY AND LANDSLIDE ANALYSIS
This paper discussed the fabricated apparatus for geotechnical analysis, specifically for soil slope stability and landslide analysis. This study used the single–group design of experimental methods and design science research methods. The study used standard tools and equipment to fabricate, such as the metal shear box, shear box cover, clamps, probe ring, probe ring gauge, gear, rotating handle, weights, and base. This fabricated Cohesiometer is a vital laboratory or in situ apparatus to get the soil's shear strength, normal stress, cohesion, and angle of internal friction to test its stability factor for a possible landslide. The results show that the Cohesiometer apparatus is comparable to the standard apparatus tested in the Modified coulombs theory, Mohr’s – coulombs theory, Coulombs theory, and Mohr’s theory. This signifies that the fabricated Cohesiometer apparatus is acceptable and comparable to standard analog apparatus; hence, the fabricated Cohesiometer formula is formulated based on the results tested in three different landslide areas. This Cohesiometer is recommended for the soil slope stability analysis for possible landslides.
