Active Earth Pressure of Narrow Cohesionless Backfill on Inclined Rigid Retaining Walls Rotating about the Bottom
(ASCE, 2020)In engineering constructions, the backfill behind retaining walls is usually narrow, and its boundary conditions are asymmetric due to the space limitation. When the retaining wall rotates about the bottom, the direction ... -
Investigation of Initial Static Shear Stress Effects on Liquefaction Resistance Using Discrete Element Method Simulations
(ASCE, 2020)Prior laboratory and in situ investigations show that monotonic preshearing can have a significant effect on the cyclic response of granular materials. The underlying mechanics that are responsible for these changes in ... -
Analytical Model for Predicting Stress Distribution and Load Transfer of Tension-Type Anchor Cable with Borehole Deviation
(ASCE, 2020)Borehole deviation is a common problem in anchor cable engineering of soil and rock, especially in long drilling holes, which affects the reinforcement effect of tension-type anchor cables, but the law of stress distribution ... -
Development of a DEM-Based Method for Modeling the Water-Induced Failure Process of Rock from Laboratory- to Engineering-Scale
(ASCE, 2020)The time-dependent hydromechanical behavior of rocks is crucial to assessing the long-term stability of rock engineering, such as reservoir rock slopes and underground waste storage facilities. This research aims at ... -
Numerical Assessment of Factors Influencing the Tensile Strength of Rocks via Pull-Off Test
(ASCE, 2020)The pull-off test (POT) is a tensile strength testing method that is widely used in concrete/mortar and was recently applied to rock mechanics. The POT can be easily performed in both the field and the laboratory. This ... -
An Efficient Disk-Based Discontinuous Deformation Analysis Model for Simulating Large-Scale Problems
(ASCE, 2020)Simulating large-scale problems are still challenging for discontinuous deformation analysis (DDA). To this end, this paper develops an efficient disk-based DDA (DDDA) model considering the efficiency in searching contact ... -
Effect of Eccentric Load on the Undrained Bearing Capacity of Strip Footings above Voids
(ASCE, 2020)This study employed finite element limit analysis (FELA) to investigate the influence of eccentric loads on the bearing capacity of footings above single and double continuous voids. Upper bound theorem (UB), lower bound ... -
Experimental Study on the Vertical Deformation of Soils due to Groundwater Withdrawal
(ASCE, 2020)Severe land subsidence caused by groundwater exploitation is one of the anthropogenic environmental problems. Even when groundwater exploitation has been limited or prohibited in some areas, it will continue in some ... -
Slope-Dynamic Reliability Analysis Considering Spatial Variability of Soil Parameters
(ASCE, 2020)Slope instability caused by earthquakes often brings huge casualties and property losses, and so it has great practical significance for seismic design and disaster prevention to evaluate the stability of slopes accurately ... -
Calculating the State Parameter in Crushable Sands
(ASCE, 2020)The state parameter (ψ) measures the distance from the current state to the critical state line (CSL) in the compression plane. The existence of a correlation between both the peak angle of shearing resistance -
Experimental Study on Mechanical Properties of Grout–Soil Interface in Anchor System of Rammed Earthen Sites
(ASCE, 2020)This paper presents an experimental study on the mechanical properties of grout–soil interfaces under different grout proportions and interface forms in conservation engineering of rammed earthen sites. Calcined ginger nut ... -
OpenMP-Based Parallel Two-Dimensional Discontinuous Deformation Analysis for Large-Scale Simulation
(ASCE, 2020)Discontinuous deformation analysis (DDA) has gained wide acceptance in geotechnical engineering. The simulation of large-scale engineering problems using DDA is computationally expensive. Thus, improving the calculation ... -
Generalized Plastic Mechanics–Based Constitutive Model for Estimation of Dynamic Stresses in Unsaturated Subgrade Soils
(ASCE, 2020)This paper presents a generalized plastic mechanics–based constitutive model for the estimation of dynamic stresses in unsaturated subgrade soils under repeated vehicle loading conditions. The stresses in subgrade soils ... -
Analysis of Drained Cavity Unloading–Contraction Considering Different Degrees of Intermediate Principal Stress with Unified Strength Theory
(ASCE, 2020)Since previous studies give little consideration to the influence of different intermediate principal stresses in the cavity contraction problem, the unified strength theory (UST) is introduced into cylindrical cavity ... -
Excess Pore Water Pressure along the Friction Sleeve of a Piezocone Penetrating in Clay: Numerical Study
(ASCE, 2020)Excess pore water pressure (EPWP) measurements taken at different positions on a penetrating piezocone into a clayey soil are believed to play an important role in correlating to its characteristics. On this subject, many ... -
