Instability of a Caisson-Type Breakwater Induced by an Earthquake–Tsunami Event
(American Society of Civil Engineers, 2016)The Tohoku coastal area in Japan suffered massive damage in the Great Tohoku Earthquake, in which a prolonged major earthquake was followed by a large tsunami. The damage mechanisms of coastal structures during earthquake–tsunami ... -
Exact Solution of the Friction Circle Method
(American Society of Civil Engineers, 2016)The modified friction circle method is still an important tool in slope-stability investigations. The theoretical soundness of this method was investigated, and it is shown here that there is theoretical inconsistency and ... -
Microstructure-Based Effective Stress Formulation for Unsaturated Granular Soils
(American Society of Civil Engineers, 2016)The principle of effective stress states that the strength and volume change behaviors of soil are governed by intergranular forces expressed in terms of a continuum quantity called effective stress. Although the principle ... -
New and Simple Equations for Ultimate Bearing Capacity of Strip Footings on Two-Layered Clays: Numerical study
(American Society of Civil Engineers, 2016)In this paper, two very simple and accurate equations are introduced that enable geotechnical engineers to determine the undrained ultimate bearing capacity of shallow strip foundations resting on two-layered clays. Results ... -
Suction-Induced Hardening Effects on the Shear Modulus of Unsaturated Silt
(American Society of Civil Engineers, 2016)The small-strain shear modulus Gmax is a key material parameter in modeling the behavior of soils subjected to dynamic loading. Recent experimental results indicate that seasonal weather interaction with near-surface soils ... -
Behavior of Geotextile-Reinforced Clay with a Coarse Material Sandwich Technique under Unconsolidated-Undrained Triaxial Compression
(American Society of Civil Engineers, 2016)This paper presents a series of unconsolidated-undrained (UU) triaxial compression tests for investigating the behavior and failure mechanism of geotextile-reinforced clay and the effects of sandwiching nonwoven geotextile ... -
Average Soil Skeleton Stress for Unsaturated Soils and Discussion on Effective Stress
(American Society of Civil Engineers, 2016)The principle of effective stress is the most fundamental and important principle in soil mechanics. It serves as the foundation of modern soil mechanics. This paper starts with a discussion of effective stress expressions ... -
Constant Water Content Compression Tests on Unsaturated Compacted Soil with Suction Measurement Using a HCT
(American Society of Civil Engineers, 2016)Soil compaction is a process used in different engineering works; from the most complex to the simplest, the quality of soil compaction indiscriminately affects the final condition of the compacted soil in terms of engineering ... -
Predicting Liquefaction-Induced Lateral Spreading by Using Neural Network and Neuro-Fuzzy Techniques
(American Society of Civil Engineers, 2016)The prediction of lateral spreading is an important task because of the complexities of lateral-spreading behavior. The aim of this work is to improve an accurate liquefaction-induced lateral-spreading prediction by using ... -
Permanent Deformation Study of Pavement Layers Using Laboratory Pavement Model Testing
(American Society of Civil Engineers, 2016)Lightly stabilized granular materials with slow-setting cementitious binders are widely used in the construction of new pavements and rehabilitation of old pavements in Australia and other countries. Higher strength and ... -
Liquefaction of Unsaturated Sands
(American Society of Civil Engineers, 2016)Recent laboratory tests and field observations have revealed that unsaturated sands are susceptible to liquefaction. Systematic investigation of liquefaction potential of unsaturated sands is, however, lacking. In this ... -
Influence of Suction History on Hydraulic and Stress-Strain Behavior of Unsaturated Soils
(American Society of Civil Engineers, 2016)An experimental study was performed to investigate the effects of suction history on the hydraulic and stress-strain behavior of unsaturated soils. Test results show that, even if the same path of net stress and suction ... -
