A Novel Limit-Equilibrium Method Based on Increments of Interslice Forces for Stability Analysis of Slopes with Weak Interlayers
(ASCE, 9/1/2023 1)The existence of weak interlayers (WIs) in slopes results in slope failure with multiple possibilities. The most likely failure modes include sliding along a curved slip surface, linear slip surface, and composited slip ... -
Capacity Change of Piles in Loess under Cyclic Axial Tension or Compression Load
(ASCE, 10/1/2023 )This study examines the capacity of single piles subjected to cyclic axial tension or compression load in the loess area under in situ compaction degree and extruding conditions. Four cyclic tension and compression loading ... -
Centrifuge Modeling of Drying–Wetting Cycle Effect on Soil Slopes
(ASCE, 9/1/2023 1)A group of well-designed centrifuge model tests were conducted to analyze the influence of drying–wetting cycles on the failure and deformation behavior of the slope. The full-field displacement was measured via the image ... -
Strength Development Behavior of Cement-Treated Mud with Emphasis on Early-Stage Performance
(ASCE, 9/1/2023 1)The vacuum preloading combined flocculation and solidification method (VP-FSCM) has been proposed in recent years to increase the efficiency of high-water-content slurries. The characteristic of the strength development ... -
Development of a Geomechanics Program for Wellbore Stability Analysis
(ASCE, 8/1/2023 1)A geomechanics program for wellbore stability analysis has been developed consisting of two modules: an analytical-based solution and a numerical-based solution. In the first part, input data are imported, including ... -
Seismic Stability and Permanent Displacement of 3D Slopes with Tension Cutoff
(ASCE, 9/1/2023 1)The magnitude of seismic displacement is an important index to evaluate the safety of slopes. The traditional Mohr–Coulomb failure criterion may overestimate the slope stability in seismic displacement calculation. Some ... -
Evaluation of Tunneling-Induced Lateral Pile Response by an Artificial Intelligence Optimization Algorithm
(ASCE, 10/1/2023 )The efficient assessment of tunneling effects on adjacent existing piles is significant for underground constructions. In this study, a new analytical approach was developed to rapidly assess lateral pile responses due to ... -
Experimental Study of the Reinforcement Mechanism for the Tunnel Support Structure in Weak Rock Masses
(ASCE, 10/1/2023 )This study aims to comprehensively investigate the reinforcement mechanism of the tunnel support structure and its supporting characteristics in layered and weak rock tunnels. Uniaxial compressive tests were carried out ... -
Effect of Particle Morphology on Strength of Glass Sands
(ASCE, 8/1/2023 1)A series of drained triaxial tests were performed on sandy soils [crushed glass (CG) and glass bead (GB)] with different mean particle sizes in order to investigate the effect of both particle size and particle shape on ... -
Mesoscopic Analysis of the Compaction Characteristics of Rockfill Materials Considering Gradation and Shape
(ASCE, 10/1/2023 )The development of high rockfill dams has imposed greater demands on the compaction quality of rockfill materials. However, because rockfill particles are subjected to crushing under the compaction of a high-powered roller, ... -
Piping-Seepage Mechanism of Tailings with Different Fine Particle Contents
(ASCE, 11/1/2023 )Piping-seepage damage is one of the major factors leading to tailings dam failure. To explore the microscopic influence mechanism of tailings with different fine content on piping development, on the basis of the indoor ... -
Seismic Performance of Coal Mine Overburden Dump Slope Using Extended Finite-Element Method–Based Voronoi Tessellation Scheme
(ASCE, 11/1/2023 )Assessment of the seismic damage of coal mine overburden (OB) dump slopes gets compromised due to negligence of the consideration of heterogeneity in the shape and size of its particles. In this paper, in situ material ... -
Dynamic Characteristics of Freezing–Thawing Aeolian Soil under Intermittent Cyclic Loading
