Time-Dependent Deformation Mechanism for Swelling Soft-Rock Tunnels in Coal Mines and Its Mathematical Deduction
(ASCE, 2020)The floor heave and the inward movement of sidewalls are often encountered in the excavation of tunnels with swelling rock properties. However, the deformation mechanism for swelling soft-rock tunnels cannot be reasonably ... -
Yield Criterion for Rocklike Geomaterials Based on Strain Energy and CMP Model
(ASCE, 2020)The yield criterion of rock is significant for the identification of the whole failure process and the stability analysis of rock engineering. Studies of yield criteria from energy aspects are critical but rare. This paper ... -
Modified Equivalent-Area Method for Calculating Factors of Safety against Deep-Seated Failure of Embankments over Deep-Mixed Foundations
(ASCE, 2020)The limit equilibrium method (LEM) and the finite-element method (FEM) commonly have been used in design to calculate the factors of safety (FS) against deep-seated failure of deep-mixed (DM) column-supported embankments ... -
Simplified Model to Predict Features of Soil–Water Retention Curve Accounting for Stress State Conditions
(ASCE, 2020)Stress state is a significant factor influencing the features of the soil–water retention curve (SWRC) under realistic in-situ conditions. The SWRC under different stress state conditions can be evaluated through experimental ... -
Interfacial Shearing Behavior Analysis of Rockfill Using FDEM Simulation with Irregularly Shaped Particles
(ASCE, 2020)A set of numerical experiments of simple shear tests of rockfill–structure interfaces were performed using the combined finite- and discrete-element method (FDEM). Each particle was modeled as a polyhedron to represent ... -
Bearing Capacity of Shallow Foundations on Unsaturated Soils: Analytical Approach with 3D Numerical Simulations and Experimental Validations
(ASCE, 2020)The ultimate bearing capacity of shallow foundations on unsaturated soils is investigated through the concept of suction-dependent effective stress. The first approach is a new analytical solution considering the influence ... -
Development of an Anisotropic Nonlinear Strength Criterion for Geomaterials Based on SMP Criterion
(ASCE, 2020)Based on the strength criterion of the nonlinear spatially mobilized plane (SMP), an anisotropic nonlinear strength criterion is presented to accurately describe the strength anisotropy of geomaterial. An anisotropic ... -
New Method to Evaluate Strengthen Efficiency by Dynamic Compaction
(ASCE, 2020)The tamping energy or tamping momentum usually is adopted to evaluate the efficiency of dynamic compaction (DC), meaning that the same tamping energy or tamping momentum leads to the same strengthening effect to the soil. ... -
Modeling Water Retention Curve of Hydrate-Bearing Sediment
(ASCE, 2020)The water retention curve is an important constitutive relation routinely incorporated into numerical stimulations of production from gas hydrate reservoirs. It has significant influences on the physical and mechanical ... -
Investigating the Scale Effect of Rock Mass in the Yangfanggou Hydropower Plant with the Discrete Fracture Network Engineering Approach
(ASCE, 2020)It is well known that there is a significant difference between the strength of an intact rock sample and that of an in situ rock mass. Studying the scale effect of a rock mass is important for the estimation of the rock ... -
Dynamic Mechanical Behavior of Granite under the Effects of Strain Rate and Temperature
(ASCE, 2020)The dynamic properties of rock under different strain rates and temperatures play an important role in the stability of rock mass. To investigate the dynamic behavior of granite specimens subjected to high strain rates and ... -
Novel Procedure for Accurately Characterizing Nonlinear Viscoelastic and Irrecoverable Behaviors of Asphalt Binders
(ASCE, 2020)The multiple stress creep recovery (MSCR) test has been extensively recognized as a more effective method for characterizing the rutting resistance of asphalt binders than the traditional linear viscoelastic (LVE) theory–based ... -
Predicting the Shear Resistance Contribution of Passive Fully Grouted Bolts to Jointed Rock
(ASCE, 2020)Based on the statically indeterminate beam model for fully grouted bolts proposed by others and taking into account the combination of the axial and shear forces activated in the bolt, an improved method was developed for ... -
