Mechanical Behaviors of Sandy Sediments Bearing Pore-Filling Methane Hydrate under Different Intermediate Principal Stress
(ASCE, 5/1/2021)Methane hydrates are an attractive source of future clean energy and are abundant in voids of sediments, in permafrost regions, and along continental slopes. Understanding the mechanical behavior of methane hydrate-bearing ... -
Bounding-Surface Plasticity Model for Drained Cyclic Behaviors of Cohesionless Soil
(ASCE, 4/1/2021)To describe the drained behaviors of cohesionless soil through a concise constitutive approach, a single-surface model is constructed on the concept of the bounding surface. Based on observations from tests, the maximum ... -
Characterization of Rock Joint Roughness from the Classified and Weighted Uphill Projection Parameters
(ASCE, 5/1/2021)To reflect the contributions of different-ordered asperities to the peak shear strength, a directional uphill projection area parameter was proposed to estimate the joint roughness coefficient (JRC) for two-dimensional ... -
Stability Evaluation Model of a Tunnel Face Excavated by the Benching Method in a Soft Silty Clay Layer
(ASCE, 4/1/2021)With the increasing construction demand for tunnels in soft silty clay layers, it is important to effectively control the face stability of a tunnel. One of the key issues for maintaining face stability is addressing how ... -
Free and Forced Vibration Analyses of Tapered Piles under Axial Harmonic Loads
(ASCE, 4/1/2021)In this study, the free and forced vibration analyses of tapered piles subjected to axial harmonic loads were carried out. The first part of the paper presents the free vibration analysis of the tapered piles using an ... -
Crack Growth in Rocks with Preexisting Narrow Flaws under Uniaxial Compression
(ASCE, 4/1/2021)Crack growth in rocks with preexisting flaws is of real concern for many rock engineering applications. The present paper considers the flaw that has a narrow gap that eventually gets closed on loading. Crack growth behavior ... -
Lightly Stabilized Loose Sands with Alkali-Activated Fly Ash in Deep Mixing Applications
(ASCE, 3/1/2021)Deep mixing using cementitious compounds are an in-situ ground improvement method for improving the strength and compressibility of loose sands. Low-calcium class F fly ash (FA) is a sustainable low-carbon replacement for ... -
Three-Dimensional Finite-Element Analysis of Pressure–Settlement Response of Sand Compaction Pile-Treated Cohesionless Deposits
(ASCE, 4/1/2021)Strength characteristics of loose to medium dense sand deposits improved by sand compaction piles (SCPs) are assessed by performing three-dimensional (3D) finite-element analysis using PLAXIS 3D. The Mohr–Coulomb model is ... -
Three-Dimensional Soil–Foundation–Superstructure Interaction Analysis of Nuclear Building Supported by Combined Piled–Raft System
(ASCE, 4/1/2021)Recently, few nuclear facilities have been proposed on soil sites worldwide. Controlling the overall and differential settlement is a difficult task for a nuclear structure that rests on a soil site. Under these circumstances, ... -
Semianalytical Solution for Dynamic Responses of Railway Track System on Unsaturated Poroelastic Half-Space Subjected to Moving Trainload
(ASCE, 3/1/2021)A track-unsaturated ground model was proposed to study the dynamic responses of the unsaturated subgrade induced by moving trainloads. The subgrade was modeled by an unsaturated poroelastic half-space, and the railway track ... -
Second-Order Reliability-Based Design of Unsaturated Infinite Soil Slopes
(ASCE, 4/1/2021)This paper presents an application of the second-order reliability method (SORM) to analyze shallow landslides considered as unsaturated infinite soil slopes. The accuracy of modeling the unsaturated infinite slope reliability ... -
