Effect of Anisotropy of Fibers on the Stress-Strain Response of Fiber-Reinforced Soil
(American Society of Civil Engineers, 2015)Reinforcing soil with fibers is a useful method for improving the strength and settlement response of soil. The soil and fiber characteristics and their interaction are some of the major factors affecting the strength of ... -
Finite-Element Analysis of Failure in Transversely Isotropic Geomaterials
(American Society of Civil Engineers, 2015)The strength and failure behaviors of geomaterials, such as soils and rocks, are commonly anisotropic because of lamination and sedimentation. The main purpose of this study is to investigate the effect of anisotropy on ... -
Soil Arching in a Piled Embankment under Dynamic Load
(American Society of Civil Engineers, 2015)Soil arching is a common phenomenon in pile-supported, geosynthetic-reinforced or unreinforced embankments resting on soft soil. Although the system behavior under static loading is well known (soil arching and bearing ... -
Seismic Bearing Capacity of Shallow Embedded Foundations on a Sloping Ground Surface
