دراسة جيوتكنيكية لبعض الخواص الفيزيائية و الكيميائية و الهندسية لتربة مدينة أبي غزة-محافظة بابل (وسط العراق)‎

Abstract EN

This research was carried out on the soil of the Abu Grag District , while is based on the investigations carried out by Al-Mawal company in the year or 2012.

The aim of this researchis the Geotechnical Evaluation of these so is soil which is important (essential) in the construction design.

This research included the aging of test well, distributed all over the city.

The depth of these wells is 15m.

This evaluation is based on the information's obtained from the field work and the results of lab.

test carried out on the compacted and not compacted samples taken from the soil of area.

The results of this research showed that the soil classified to clay with high and low plasticity, and clayey silty sand with content gypsum for final depthThe number of vales (N) of standard penetration test (SPT) is between (5-50/6" blow) and water table is between (1.20-1.40)m below natural ground surface (N.G.S).

The moisture content (M.C) is between (19.4%-29.1%) of samples weight.

The percentages of clay in the grain distribution is between (14%-61%), and for silt between (21%-26%), and for sand between (17%-62%).

The value of the liquid limit (L.L) is (41.5%-57%), the plasticity limit (P.L) is (17.3%-41.0%) and the plasticity index (P.I) is (8.6%-21.0%).

The dynamic and static methods are used to estimate the bearing capacity .

The value of allowable bearing capacity is (3.21-11.38) ton/m2,in using the static method while in using dynamic method the value is (27.3-5.0)ton/m2.

The investigation and lab test showed that soil needs treatments for the sake of constructing engineering Projects on it .
