GEOTECHNICAL ASSESMENT FOR YAYCHEE TOWN- KIRKUK/NORTH IRAQ

Abstract

The research includes evaluation of geotechnical properties of Quaternary deposits in various locations in terms of Yaychee / Kirkuk, physical tests showed that the soil moisture content (mc%) in areas ranging from (1.95 to 16.74%), while showing the values results of specific weight ( Gs) ranging from (2.65 to 2.76), and the results of the grain size analysis showed that the soil study area is homogeneous and contains a wide range of different sizes and granules in the proportion of volumes grained constituent of the soil .Az was soft soil is predominant in the study area and rates mixed with a less than soils coarse ratios according to the results of the atterberqe limits (Liquid Limit and plastic Limit) showed that the soil type (CL) of mud and a low-plasticity with the exception of soil second location which Silty and Low plasticity (ML), while the results showed the engineering tests of the examination direct shear values that internal friction angle ranged between (35-41°) and the cohesion between (60-100 kpa), while the results of the Consolidation test in the study area showed transaction values ranging from effective pressure (Po) (16.09-21.39 kpa ), and the pressure of the preconsolidation (Pc) (65-240 kpa), and the proportion of voids (eo) (0.52 -1.061), and compression modulus (Cc) (0.22-0.339), and swelling coefficient (Cr) (0.029- 0.166), the soils excessively Consolidation O.C.R, and the chemical analysis it was observed low proportion of gypsum, and organic content of soils base and low for the content of soluble salts.
