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 Al-Emara city.  The  ground  conditions  in  the  study  area indicate  that  there  is  a  deep  layer  (36m)  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 pre-consolidation 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).
