Optimization of Vibrocompaction Design for Liquefaction Mitigation of Gravity Caisson Quay Walls
(American Society of Civil Engineers, 2016)Gravity-type caisson walls are a type of popular but easily damaged waterfront construction structure, especially in seismic regions. Various forms of mitigation have been successfully applied to improve their performance ... -
Finite-Element Analysis on the Effect of Subsoil in Reinforced Piled Embankments and Comparison with Theoretical Method Predictions
(American Society of Civil Engineers, 2016)This paper presents a finite-element (FE) analysis of the effect of subsoil in a reinforced piled embankment and compares the findings with predictions from a theoretical method. It shows that the subsoil can carry as much ... -
Influence of Initial Water Content on the Mechanical Behavior of Unsaturated Sandy Clay Soil
(American Society of Civil Engineers, 2016)The mechanical behavior of a sandy clay soil was investigated by a series of constant water content triaxial tests on unsaturated samples with suction measurements. The tests were carried out in double-cell triaxial cells ... -
Influence of Shear on Permeability of Clayey Soil
(American Society of Civil Engineers, 2016)The variation of stress–strain state induces changes in the permeability of clayey soil and then affects the properties of seepage and consolidation. In previous studies, variations of the permeability of soil in shear ... -
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 ... -
3D Numerical Study on the Growth and Coalescence of Pre-existing Flaws in Rocklike Materials Subjected to Uniaxial Compression
