Variability of Soil Properties and Reliability of Empirical Equations on Soil Settlement Predictions (Ömer Bilgin and Eman Mansour) Foundation Engineering in the Face of Uncertainty: Honoring Fred H. Kulhawy (2013)

The engineering properties of soils can vary quite dramatically throughout a site, and even more so from site to site. Several soil test data have been collected from numerous projects to perform a statistical analysis ...

Anchored Sheet Pile Wall Design in Expansive Soils (Ömer Bilgin and Eman Mansour) Proceedings of the 18th International Conference on Soil Mechanics and Geotechnical Engineering (2013)

Expansive soils cause damage to civil engineering structures in various parts of the world, because they swell when absorb water and shrink when dry out. Due to swelling pressures, retaining walls can be subjected to ...

Studying Buried Pipeline Behavior Using Physical and Numerical Modeling (Ömer Bilgin and Harry E. Stewart) GeoCongress 2012: State of the Art and Practice in Geotechnical Engineering (2012)
