Behavior of a Structured Piled Beam–Slab Foundation for a Wind Turbine under Multidirectional Loads in Sand
(ASCE, 3/1/2021)With wind farm development, a new type of foundation, the piled beam–slab foundation, was invented to support wind turbines on land. Although this foundation enables a lower-cost investment, its structure is complex. Wind ... -
Spatial–Temporal Variation of Soil Sliding Probability in Cohesive Slopes with Spatially Variable Soils
(ASCE, 3/1/2021)Landslide is a common and severe geohazard that may pose significant risk to adjacent structures such as buildings and buried pipelines. Identification of the failure slip surface is critical for the assessment and management ... -
Improved Analytical Soil Arching Model for the Design of Piled Embankments
(ASCE, 3/1/2021)Because analytical soil arching models are fundamental for the design of piled embankments, numerous soil arching models were proposed for this purpose. However, the results obtained from various soil arching models differ ... -
Stress-Dilatancy Behavior of MICP-Treated Sand
(ASCE, 3/1/2021)Biocementation of soil using microbial-induced carbonate precipitation has become a new approach for soil treatment. The biocemented sand behaves differently from uncemented sand. One of the major differences is the ... -
Experimental Investigation on Shear Behavior of Intact Sandstones under Constant Normal Stiffness Conditions
(ASCE, 2/1/2021)The shear behavior of intact cubic sandstones was studied under constant normal stiffness (CNS) conditions using self-designed equipment. A series of direct shear tests on intact sandstone blocks was conducted with initial ... -
1D Constitutive Model for Expansive Soils
(ASCE, 3/1/2021)Modeling the element behavior of expansive soil with cyclic variations of its water content in stress and time dimensions is a challenging topic. In this paper, a one-dimensional (1D) model will be proposed to provide an ... -
Solution of the Ultimate Bearing Capacity at the Tip of a Pile in Anisotropic Discontinuous Rock Mass Based on the Hoek–Brown Criterion
(ASCE, 2/1/2021)An analytical method will be proposed to investigate the bearing mechanism of piles in an anisotropic discontinuous rock mass. Based on the characteristic line method, the discontinuous part of the rock is considered as ... -
Elastoplastic Model of Sand Based on Double-State Parameters under Complex Loading Conditions
(ASCE, 2/1/2021)Based on the existing unified hardening model, the double-state parameters unified hardening (DPUH) model is proposed, which can take into account the initial density and confining pressure dependent characteristics and ... -
Multiple Nonlinear Regression Models for Predicting Deformation Behavior of Concrete-Face Rockfill Dams
(ASCE, 2/1/2021)Deformation assessment and control are important issues in the construction of concrete face rockfill dams (CFRDs). The design and construction of CFRDs require deformation behavior that can be estimated rapidly to support ... -
Experimental Study of Laterally Loaded Pile Group in Square Arrangement near Sloping Ground
(ASCE, 2/1/2021)The prediction of the pile response near a slope has not been fully explored and remains challenging for designers. In this study, an experimental investigation is planned to explore the behavior of laterally loaded pile ... -
Arching Development in Transparent Soil during Multiple Trapdoor Movement and Surface Footing Loading
(ASCE, 3/1/2021)Soil arching exists in many earth structures, such as pile-supported embankments, tunnels, buried pipes, and retaining walls. These earth structures are sometimes subjected to surface footing loading. Limited studies showed ... -
Semianalytical Solution for Long-Term Settlement of a Single Pile Embedded in Fractional Derivative Viscoelastic Soils
(ASCE, 2/1/2021)This paper proposes a semianalytical solution to analyze the long-term settlement of a single pile embedded in fractional derivative viscoelastic soils under time-dependent loading. In this paper, a three-dimensional (3D) ... -
Performance of Driven Grouted Micropiles: Full-Scale Field Study
(ASCE, 2/1/2021)A new installation method for micropile is introduced, called driven grouted micropiles (DGMs), in which closed-end perforated steel pipes are driven to the refusal depth using a light hammer and grout is injected incrementally ... -
On the Soil Slope Failure Mechanism Considering the Mutual Effect of Bedrock and Drawdown
(ASCE, 2/1/2021)In reservoirs and embankment areas, frequent water-level fluctuations, especially water drawdowns, often produce instability problems or landslides in the slopes overlying bedrocks. A series of centrifuge model tests were ... -
