Prediction of Rockburst Based on Multidimensional Connection Cloud Model and Set Pair Analysis
(ASCE, 2020)Prediction of rockburst involves numerous random and fuzzy indicators asymmetrically distributed in finite intervals. Herein, a novel multidimensional connection cloud model was introduced to depict uncertainties and ... -
Empirical and Conceptual Challenges in Hydraulic Fracturing with Special Reference to the Inflow
(ASCE, 2020)In this paper, a systematic study was carried out to computationally explore the significance of different mechanisms involved in hydraulic fracturing treatments in practice, with special reference given to the hydrofracture ... -
Comprehensive Evaluation of Strength Criteria for Granite, Marble, and Sandstone Based on Polyaxial Experimental Tests
(ASCE, 2020)Cubic specimens of three rocks—granite, marble, and sandstone, representing very strong rock, moderately strong rock, and weak rock, respectively—were tested under polyaxial stress. The objective was to determine the optimal ... -
Performance of New Type of Foamed Concrete in Supporting Tunnel in Squeezing Rock
(ASCE, 2020)For tunneling in squeezing rock, large deformation induced by tunnel excavation and creep of squeezing rock has been a great challenge during construction. This large deformation would keep growing for a long time, ... -
Efficient Beam–Column Finite-Element Method for Stability Design of Slender Single Pile in Soft Ground Mediums
(ASCE, 2020)Slender single piles are extensively used but susceptible to buckling when embedded in soft ground mediums. Owing to the complexity of soil properties, the soil-structure interaction (SSI) response is sometimes very ... -
Particle Breakage of Calcareous Sand and Its Correlation with Input Energy
(ASCE, 2020)A series of confined compression tests and triaxial tests under different test conditions were carried out on two types of calcareous sand from the South China Sea. Notably, drained and undrained tests under monotonic, ... -
Response of High-Density Polyethylene Geomembrane–Sand Interfaces under Cyclic Shear Loading: Laboratory Investigation
(ASCE, 2020)Geomembranes are thin polymeric sheets used as barriers to liquid or gas intrusion in earth structures due to their low permeability. The mechanical behavior of geomembrane-soil interfaces plays an important role in the ... -
New Algorithm for Simulating Grout Diffusion and Migration in Fractured Rock Masses
(ASCE, 2020)It is of crucial importance to develop an efficient numerical method to investigate the mechanism of grout diffusion and migration in fractured rock masses. However, most existing models only concentrate on the grout flow ... -
Discrimination of Particle Breakage below Pile Tip after Model Pile Penetration in Sand Using Image Analysis
(ASCE, 2020)Particle breakage is a common phenomenon in granular soils and has been well observed during laboratory and in-situ pile studies. In this paper, an image analysis approach was developed to investigate the particle breakage ... -
Estimation of First and Periodic Roof Weighting Effect Interval in Mechanized Longwall Mining Using Numerical Modeling
(ASCE, 2020)The main factors that make longwall mining projects economical are roof control and prediction of roof behavior in roof caving and face advance. Sudden and unexpected roof fall not only endangers the safety of employees ... -
Influence of Point Source on Love-Type Waves in Anisotropic Layer Overlying Viscoelastic FGM Half-Space: Green’s Function Approach
(ASCE, 2020)This article is framed to examine the influence of heterogeneities, viscosity, initial stress, rigidity and density ratios, and thickness on traversal characteristics of Love-type surface wave in a heterogeneous anisotropic ... -
Three-Dimensional Simulation of Seismic Slope–Foundation–Structure Interaction for Buildings Near Shallow Slopes
(ASCE, 2020)Buildings constructed adjacent to the slope crest in seismically active areas might be exposed to serious danger when they are subjected to strong earthquake excitations. The ground conditions can influence the seismic ... -
Experimental and Analytical Study on Uplift Loading Capacity of Strip Plate Anchors Near Sand Slope
(ASCE, 2020)The aim of this study is to investigate the uplift behavior of horizontal strip plate anchors constructed at a distance to the slope crest. A series of uplift load tests was conducted in laboratory for scaled strip plate ... -
Limit-Equilibrium Analysis of Stability of Footwall Slope with Respect to Biplanar Failure
(ASCE, 2020)Biplanar failure is the most common instability type of footwall slopes, with a steeply dipping joint (typically the bedding plane) and a gently dipping joint (i.e., the daylighting toe joint) forming the basic failure ... -
