Effect of Sand Compaction Piles on the Swelling and Shrinkage Behavior of Expansive Soil
'is study aims to investigate the effect of sand compaction piles on the swelling and shrinkage behavior of expansive clay soil. A series of experimental laboratory tests were carried out using the modified Proctor mold and a circular footing. 'ediameter of the sand compaction pile was selected to give a replacement area ratio equal to 57%. To model the swelling ... Read more

Numerical assessment of rectangular tunnels configurations using support vector machine (SVM) and gene expression programming (GEP)
Rectangular tunnel boring machine (TBM) is applied for the tunnels’ excavation including a cross section of circular and rectangular shape within the various rocks and soil strata. Excessive structural forces, which is produced within tunnel linings, might affect the serviceability and safety of tunnels whose forces acting on tunnels linings during the initial design period have to be accurately calculated. ...

Studying the Effect of Cushion Properties on the Behavior of Unconnected Piled Raft Foundation
At the last decades, the design of piled raft foundation has been evolved in order to provide sufficient bearing capacity and reduction in settlement. While, minimum number of piles should be used for economical design. For this purpose, the concept of settlement reducer piles was presented. This system depend on using a few number of pile for reducing the settlement ... Read more

The effect of underground columns on the mitigation of liquefaction in shaking table model experiments
The effect of underground deep mixed columns on mitigation of liquefaction was studied by running shaking table model experiments. The effects of several factors like frequency of input motion, the degree of drainage, column length, diameter, column spacing and boundary condition were studied. Moreover, the volumetric strain, the pore water pressure ratio, the rates of generation and dissipation of the ... Read more

Geotechnical Properties of Expansive Clay Shale in El-Mahrowsa, Qena, Egypt
This study aims to investigate the geotechnical properties of expansive clay shale in El-Mahrousa region, Qena, Egypt. For this purpose, two sites were chosen and three undisturbed samples were taken within the active zone at depths 1.0 m, 2.0 m and 3.0 m below the ground surface for each site. Different laboratory tests were carried out including, natural water content, ... Read more

Correlation between Unconfined Compression Strength (UCS) and Index Properties of Soil in Assiut Governorate, Egypt
Experimental tests are very important to determine the engineering properties of soils in geotechnical engineering. Special expertise and care are required to perform these tests. The unconfined compression test is also one of them. Thus, there is a need to develop models to quickly predict the unconfined compression strength of soils. The researchers attempted to develop correlations to predict the ... Read more

Effect Of Sand Compaction Piles on the Behavior of Expansive Soil Mohammed M. A. Hussei
One of the most common mitigation heave methods for foundation on expansive clay soil is the full or the partial shallow removal of expansive clay soil and replacement with non-expansive soil, usually used sand cushion (SC). Foundation engineers often suggest some arbitrary thickness for sand cushion without considering the depth of the active zone, which is the zone within which ... Read more

Effect of Bagasse Ash on The Behavior of Expansive Clay in ELSalheya Area, Qena, Egypt
In recent years, the use of various waste materials in ground improvement has gained considerable attention worldwide in view of increasing costs of waste disposal and environment constraints. One of these waste materials is the sugarcane bagasse ash, which is obtained from the burning of bagasse in sugar producing factories. Qena governorate which is situated at 594 km south of ...

INFLUENCE OF PILE SUPPORTING EXCAVATION PROPERTIES ON EXISTING PILE FOUNDATIONS
One of the main design constraints is to prevent damages to adjacent buildings,especially during excavation for basement construction. As excavation proceeds, the surrounding soils will move toward the excavation and their movement will induce bending moments and deflections in the existing pile groups. The existing pile response due to the excavation-induced lateral soil movements had been studied previously by using ... Read more
