| Abstract | ||
| This paper describes the geotechnical characteristic of soil located at Al-Emara city southern Iraq. The paper presents the data advanced from the field investigations performed at many projects at AlEmara city. The ground conditions in the study area indicate that there is a deep layer (36 m) deep consisting of different soils. Namely, the records of boring exploration include the results of laboratory tests on samples taken from the site in addition to the results of field tests such as cone penetration tests, standard penetration tests. According to the test results and soil profiles, the stratification of layers was described for each borehole according to the test results. The paper aims at determination of mathematical correlations among the soil parameters determined from the laboratory and field tests from these relationships, several correlations were obtained from which prediction for geotechnical properties of various soils can be made. Several relationships were obtained from the field and laboratory properties of the soil, , the plasticity index, the preconsolidation pressure, cone penetration (cone resistance qc, friction sleeve fs) with depth. The relationships include the relation between the standard penetration test number (N60) and cone penetration resistance (qc) ,sleeve resistance (fs), the relation between cone penetration resistance (qc) and cohesion of soil (c) , the relation between cone penetration resistance (qc) and angle of shearing resistance (Ø),The relation between cone penetration resistance (qc) and undrained shear strength (cu) .In addition the relationships include the relation between unconfined compressive strength (qu) and constrained modulus of elasticity (D) | ||
