Abstract
The objective of this thesis is to investigate the engineering properties of the soils found from Limat to Shara and understand the nature of the soils. Arba Minch town is located in Gamo Gofa Zone in SNNPRS at a distance of about 505km from the National Capital city, Addis Ababa, and 270km far from the Regional Capital city, Hawassa. Arba Minch town is one of the rapidly developing towns in Ethiopia and new construction activities were appearing in the town. Investigating the characteristic of supporting soil is vital in order to have a safe and stable foundation. To achieve this objective, in order to determine the engineering properties of soils were accompanied on selected 24 soil samples, which were taken from Limat to Shara at not more than 500m interval, and the procedure used for analysis was done according to ASTM standard. This paper presents the field and laboratory test results of soils that were performed to determine the Engineering properties of soils from Limat to Shara. The test results showed that the field density ranges from 1.61 to 1.96g/cc. NMC ranges from 5.22 to 33.58%. LL ranges from 28.04 to 64.23%, PL ranges from 20.68 to 32.06%, and PI ranges from 4.16 to 33.21%. And from FSI results 12.5% are medium expansive soils were obtained. From plasticity characteristics of the study area falls in low to high plasticity characteristics are observed. The USCS classification soils are classified as CH, MH, CL, ML, SC, SC-SM, GC, and GC-GM. And AASHTO classification of soils is fallen in A-2-4, A-4, A-6, A-7-5, and A-7-6. The Compaction test result showed that maximum dry density (MDD) of the study area ranges from 1.57 to 1.93g/cm3 and the optimum moisture content (OMC) ranges 14.40 to 30.50%. The unconfined compressive strength test result ranges from 99.10 to157.17kPa. And direct shear test results, internal friction angle (Φ) and cohesion (C) falls for TP-11, C = 10.71kPa and Φ = 35.37°, for TP-12, C = 9.42kPa and Φ=36.80°C.Finally, from dimensional consolidation test results, the Compression index, Cc ranges from 0.43 to 0.53, Swelling index, Cs ranges from 0.06 to 0.1, and Pc vary between 67 to 98kPa.
