Influences of Initial Water Content and Roughness on Skin Friction of Piles Using FBG Technique
(American Society of Civil Engineers, 2017)A series of pullout tests were conducted on a model pile in a soil with different initial water contents and different pile surface roughnesses to study their influences on pile skin friction. To measure axial strains and ... -
Experimental Investigations on Load Transfer of PHC Piles in Highway Foundation Using FBG Sensing Technology

Generalized Solutions for Axially and Laterally Loaded Piles in Multilayered Soil Deposits with Transfer Matrix Method
(American Society of Civil Engineers, 2017)To investigate the influence of the axial force and its distribution along the pile shaft on the response of laterally loaded piles, a generalized solution is proposed based on the transfer matrix approach, in which the ... -
Bearing Capacity of Shallow Strip Foundations in Sand under Eccentric and Oblique Loads
(American Society of Civil Engineers, 2017)An empirical nondimensional reduction factor is proposed in this paper, which can be used for determining the ultimate bearing capacity of eccentrically and/or obliquely loaded shallow strip foundations embedded in sand. ... -
Numerical Modeling of Failure Process of Soil Slopes
(American Society of Civil Engineers, 2017)A finite-element analysis program was developed to analyze the progressive failure of a soil slope based on the progressive failure mechanism. The shear element was developed to comprehensively characterize the shear zone, ... -
Progressive Failure Behavior and Mechanism of Soil Slopes under Dynamic Loading Conditions
(American Society of Civil Engineers, 2017)Dynamic loading is a major cause of landslides with significantly different behavior from static loading. A series of centrifuge model tests was conducted to investigate the progressive failure behavior of slopes under ... -
Estimation of Maximum Annular Pressure during HDD in Noncohesive Soils
(American Society of Civil Engineers, 2017)This study investigated the effectiveness of estimating the maximum allowable annular pressure during horizontal directional drilling (HDD) in noncohesive soils by using two theoretical cavity-expansion solutions (small ... -
Modeling Single Piles Subjected to Evolving Soil Movement
(American Society of Civil Engineers, 2017)To design passive piles, it is critical to incorporate the impact of lateral soil movement (ws) and its profiles. This may be conveniently realized by using appropriate input parameters and a three-layer analytical model ... -
SH Wave Propagation in a Finite Thicker Layer of the Void Pore Sandwiched by Heterogeneous Orthotropic Media
(American Society of Civil Engineers, 2017)The present paper investigates the propagation of SH waves in a finite thicker layer of the void pore sandwiched by heterogeneous orthotropic media. In the upper semi-infinite medium initial stress, density and shear moduli ... -
Time and Strain-Rate Effects on Viscous Stress–Strain Behavior of Plasticine Material
(American Society of Civil Engineers, 2017)A plasticine material exhibits the characterized viscous stress–strain behavior with some similarity to the behavior of clayey soils. This paper presents a series of experimental tests, which include oedometer tests, ... -
Stress-Dependent Behavior of Artificially Structured and Reconstituted Marine Soils
(American Society of Civil Engineers, 2017)Very few studies have addressed the systematic study on the stress-dependent behavior of cement/lime-treated structured and reconstituted soils from the viewpoint of the constrained modulus. The influence of cement/lime ... -
Analysis of the Influences of Sampling Bias and Class Imbalance on Performances of Probabilistic Liquefaction Models

Load-Carrying Mechanism of Vertical Plate Anchors in Sand
(American Society of Civil Engineers, 2017)An experimental study on the load-carrying mechanism of vertical plate anchors is presented and discussed. It was found that, with a shallow anchor, the rupture surface reached the ground surface, leading to a general shear ... -
Mean Parametric Monte Carlo Study of Fill Slopes
(American Society of Civil Engineers, 2017)Slope stability analysis has traditionally been performed using a deterministic approach. However, it has strongly been debated that the use of only the factor of safety in slope stability analysis does not explicitly ... -
Effect of Gradation and Particle Shape on Small-Strain Young’s Modulus and Poisson’s Ratio of Sands
(American Society of Civil Engineers, 2017)The influence of gradation and particle shape on the small-strain Young’s modulus of dry sands is investigated through a comprehensive set of resonant column tests in the flexural mode of vibration. Experiments are performed ... -
Grouting Diffusion Characteristics in Faults Considering the Interaction of Multiple Grouting
(American Society of Civil Engineers, 2017)In this study, a testing device was developed to analyze the characteristics of grouting diffusion in faults. To include the interaction of multiple grouting applications, tests consisting of four applications of grout ... -
Deformation Response of an Existing Tunnel to Upper Excavation of Foundation Pit and Associated Dewatering
(American Society of Civil Engineers, 2017)Deep excavation clearly impacts existing underlying subway tunnels and threatens their operational safety. The prediction of existing tunnel deformation induced by nearby excavation is a major concern for urban construction. ... -
