ABSTRACT
This geotechnical study delves into the soil properties at multiple borehole points to assess their suitability for construction and their propensity for ground settlement. Emphasizing the effects of particle size on moisture content, the investigation offers insights into the intricate relationship between soil composition and water content. Multiple boreholes were selected within the study area. Soil samples were extracted from these boreholes at varying depths: 0.5m, 1m, 1.2m, 0.7m, 1.5m, and 2m, ensuring a comprehensive representation of subsurface conditions. Laboratory Testing, the collected soil samples underwent a battery of geotechnical tests which includes Moisture Content Analysis, Particle Size Distribution (Sieve Analysis), Specific Gravity Measurement and Atterberg Limit Tests (liquid limit, plastic limit, and plasticity index measurements). The findings from the analysis of various borehole points vividly illustrate the profound influence of particle size distribution on soil moisture content. Borehole Point 1 (1m and 2m depths) Moisture content declined from 19% at 1m to 17% at 2m, showcasing a distinctive trend of decreasing moisture content with depth. Borehole Point 2 (0.5m and 1.5m depths), Moisture content remained relatively consistent between 19% at 0.5m and 18% at 1.5m. This remarkable consistency suggests a finely tuned balance between particle size and moisture content. Borehole Point 3 (0.7m and 1.2m depths), the substantial increase in moisture content, from 18% at 0.7m to 22% at 1.2m, vividly illustrates the effects of finer particles at greater depths. Borehole Point 4 (0.9m and 1.8m depths), Although moisture content decreased with depth, values of 23% at 0.9m and 21% at 1.8m highlighted the prevalence of relatively high moisture levels. In conclusion, this study underscores the intrinsic relationship between particle size distribution and soil moisture content.
