Generalized Consolidation Theory for Anisotropic Saturated Soils
(American Society of Civil Engineers, 2016)Darcy’s law of fluid flow and the stress equilibrium equations of anisotropic media, coupled with the mass conservation equations of fluid, are studied on the basis of the model of constitutive equations for both effective ... -
Uplift Capacity of Anchors in Layered Sand Using Finite-Element Limit Analysis: Formulation and Results
(American Society of Civil Engineers, 2016)The vertical pullout capacity of strip and circular plate anchors embedded horizontally in a layered sandy medium was computed by using the plane strain and axisymmetric lower-bound limit analyses in combination with finite ... -
Behavior of Geosynthetic Reinforced Soil Foundation Systems Supported on Stiff Clay Subgrade
(American Society of Civil Engineers, 2016)A series of laboratory model tests was performed to investigate the behavior of geosynthetic reinforced stiff clay foundation systems under circular loading. The footing consisted of a rigid circular steel plate with a ... -
New Evaluation Method for Liquefaction of Ground Using Dynamic Liquefaction Analysis Method and Its Application
(American Society of Civil Engineers, 2016)Nankai megathrust earthquakes are expected to occur with a return period of approximately 90–200 years along the fault of the Nankai Trough. Because they are interplate earthquakes, it is predicted that they will cause ... -
Inversion of Critical Slip Surface Parameters for a Landslide Disaster Using the Bionics Algorithm
(American Society of Civil Engineers, 2016)Two key issues in landslide forecasting are finding the critical slip surface and determining its parameters. Generally, these issues are two parts of one problem. To solve this problem, a new two-phase search method is ... -
