CONSOLIDATION BEHAVIOR OF EXPANSIVE SOIL: THE CASE OF BOLE BESHALE IN ADDIS ABABA
This study is carried out Bole Beshale in Addis Ababa with the aim to assess Consolidation Behavior of Expansive Soil. Expansive nature of soils often controls the design and cost of construction projects, predominantly light weighted and shallowly founded structures. A geotechnical secondary data, a large quantity of drilling and laboratory testing data, from ongoing projects were taken and filtered out and utilized for this research. From Bole Beshale 40/60 condominium site, out of 116 boreholes a total of 38 borehole (which serves to build 19 blocks) were purposefully selected to represent the study area. Relevant laboratory test results in the selected boreholes are also considered and data obtained from the field investigation were systematically organized to correlate in the selected section. Index properties shows that the soils are classified as high plastic silt (MH) and high plastic clay (CH) in Unified Soil Classification System (USCS). These soils show high plasticity index to imply that the soil contains dominantly Smectites clay minerals. The soil exhibited medium to high compressibility and also exhibit high rates of consolidation. As liquid limit (LL) and plasticity index (PI) increases, compression index (Cc) increases. Correlations are established using LL, PI, and Cc. And shows that when liquid limit (LL) and plasticity index (PI) increases, compression index (Cc) increases. Correlation between both calculated and laboratory measured compression indices were found to be strong.
