Improvement of Soft Soil Properties Using Dynamic Compaction with Stone Columns: Case Study (AL-Mualla Site-Yeman)
Volume 31, Issue 20 , November 2013, Page 1-10
Abstract
Dynamic compaction was considered as one of a deep compaction method which was used to improve the soil properties. Also it was used to save cost and time in comparison with other methods.The ...

Volume 31, Issue 20 , November 2013, Page 217-237
Abstract
Gypseous soils as any other soils deform under loading, this deformation differs greatly between its dry state and its soaked state. This deformation also differs when the loading is ...

Volume 31, Issue 20 , November 2013, Page 238-262
Abstract
This research aims to assess some geotechnical properties and aquifer parameters and consequently the applicability of predicting its properties from surface electrical resistivity. ... Read More ...Geotechnical Properties of Compacted Silty Clay Mixed With Different Sludge Contents
Volume 31, Issue 20 , November 2013, Page 263-279
Abstract
The presence of organic matter in soil may cause different problems depending on many factors such as type and contents of these organic materials. A testing program was carried out ... Read More ...Total and Matric Suction in Unsaturated Soil with the Existence of Different Salts Content
Volume 31, Issue 20 , November 2013, Page 280-298
Abstract
Soils located above the groundwater table are generally unsaturated and exhibit negative pore-water pressures. A soil-water characteristic curve (SWCC) that relates the water content ... Read More ...Behavior of Experimental Model of Piled Raft Foundations on Clayey Soils
Volume 31, Issue 20 , November 2013, Page 288-408
Abstract
Piled raft foundations are a geotechnical composite construction consisting of three elements: piles, raft and soil. In the design of piled rafts, the load is assumed to be shared between ... Read More ...Effect of Geotextile Reinforcement on Flexible Pavement Roads
Volume 31, Issue 20 , November 2013, Page 299-315
Abstract
A field full scale flexible road is constructed and the effects of geotextile reinforcement in paved road are tested by measuring the occurred rutting. The effect of different numbers ... Read More ...Influence of Poypropylene Fibers on the Soil Stabilization
Volume 31, Issue 20 , November 2013, Page 316-323
Abstract
In this paper the polypropylene fiber was chosen as the additive material to know how it is effect on the soil stabilization, which it is used as additive for concret mixture; the polypropylene ... Read More ...Stability Behavior of Lime Stabilized Gypseous Soil
Volume 31, Issue 20 , November 2013, Page 324-338
Abstract
In arid and semi-arid zones, gypsum (CaSO4.2H2O) is one of the soluble of the common minerals that found in soils. In Iraq, gypseous soils is a worldwide stability problem that causes ... Read More ...Effect of Suction on Volumetric Yielding Behavior under Different Initial Conditions for Fine-Grained Soils
Volume 31, Issue 20 , November 2013, Page 339-358
Abstract
The unsaturated soils are difficult to consider within the framework of classical (saturated) soil mechanics. In general, the unsaturated soil is stiffer than the saturated one (hardening), ... Read More ...Total Suction Measurement of Unsaturated Artificial Gypsified Soil Using the Chilled-Mirror Hygrometer Technique
Volume 31, Issue 20 , November 2013, Page 359-374
Abstract
Total suction is the sum of the matric and the osmotic suction of the soil. Various methods are used to measure the total suction of the soil. One of the methods is the chilled–mirror ... Read More ...Effect of Recharging Primary Treated Domestic Wastewater on the Soil Characteristics
Volume 31, Issue 20 , November 2013, Page 375-387
Abstract
A study was carried out to investigate the effects of recharging primary treated domestic wastewater on soil characteristics by special recharge-recovery method developed and practiced ... Read More ...A Comparative Study between Piled-Raft and Two Soil Improvement Techniques
Volume 31, Issue 20 , November 2013, Page 409-421
Abstract
This investigational study was directed to establish the correlation between piled raft foundation and two soil improvement techniques, stone columns and lime columns to evaluate the ... Read More ...Distribution of some Heavy Metals Pollution Caused byAl- Daura Refinery in the Surrounding Region
Volume 31, Issue 20 , November 2013, Page 422-434
Abstract
Due to the higher increase in the oil industry activities in Iraq, since there are a little information of the environmental status of the areas around the refinery locations, and the ... Read More ...Experimental Study on the Behavior of Skirted Foundation Rested on Soft Clayey Soils
