RISOne-Dimensional Consolidation of Multilayered Soil with Continuous Drainage Boundaries and Under Time-Dependent Loading
Publisher: ASCE
Abstract: In the practice of reclamation engineering, surcharge loading is gradually applied to preconsolidate soft clayed soil. The in situ drainage boundaries are usually not perfect and can be in a state between fully impermeable ...
Effects of Curing Temperature and Stress on Small-Strain Stiffness of Cemented Marine Clay
Publisher: American Society of Civil Engineers
Abstract: The deep cement mixing (DCM) method is widely used for ground improvement, with soils within DCM columns often subjected to varying curing temperatures (Tc) and curing stresses (Sc). Their effects on shear stiffness at ...
New Model for Predicting Permanent Strain of Granular Materials in Embankment Subjected to Low Cyclic Loadings
Publisher: ASCE
Abstract: Estimating the permanent strain of granular materials in embankments subjected to cyclic loading is a major challenge for transport engineering projects. In practice, the development of permanent strain can be divided into ...
Nonlinear Model for the Stress–Strain–Strength Behavior of Unsaturated Granular Materials
Publisher: ASCE
Abstract: Granular materials are typically used as fills in earth structures, including foundation, embankment, and slope. The majority of these granular materials are built and maintained in unsaturated conditions. It is still an ...
A Finite Strain Elastic-Viscoplastic Consolidation Model for Layered Soft Soils Considering Self-Weight and Nonlinear Creep
Publisher: ASCE
Abstract: This paper presents a numerical model, called consolidation settlement - elastic-viscoplastic (CS-EVP), for the consolidation of layered soft soils, including soil self-weight and time-dependent compressibility effects. ...
Axial Cyclic and Static Behavior of FRP Composite Seawater–Sea Sand Concrete Piles Ended in a Rock Socket
Publisher: ASCE
Abstract: Pile foundations supporting high-rise buildings are generally subject to cyclic loading because of dynamic loading. The corrosion of steel materials in pile foundations is another major concern, especially for piles in a ...
Behavior of FRP-Confined Sand and Cemented Sand under Axial Compression
Publisher: American Society of Civil Engineers
Abstract: Fiber-reinforced polymer (FRP)-confined concrete tubular columns have been extensively studied, where the design of the column is usually based on stiffness and strength. The ability to sustain large deformations without ...
Axial and Circumferential Behavior of Rock-Socketed FRP-SSC Composite Piles Monitored by Distributed Optical Fiber Sensors
Publisher: American Society of Civil Engineers
Abstract: Traditional pile foundations in harsh marine environment may experience steel corrosion or concrete deterioration. Besides, conventional measuring devices such as strain gauges and vibrating wire extensometers are sensitive ...
Coupled Consolidation–Leaching Behavior of Cement-Stabilized Highly Arsenic-Contaminated Marine Clay
Publisher: American Society of Civil Engineers
Abstract: Deep cement mixing (DCM) is a popular in situ soil stabilization method, while the investigation on long-term coupled consolidation and contaminant leaching behavior of cement-stabilized contaminated soil is limited. In ...
Numerical Model for Coupled Finite Strain Consolidation and Heat Transfer in Layered Clayey Soils Considering Thermal Creep
Publisher: American Society of Civil Engineers
Abstract: A numerical model that accounts for fully coupled long-term large strain consolidation and heat transfer provides a more realistic analysis for various applications, including geothermal energy storage and extraction, ...
