Probabilistic Assessment for Slope Using the Generalized Chebyshev Inequalities
(ASCE, 4/1/2020 1)This paper aims to estimate the probability of failure (Pf) of slope based on Chebyshev inequalities. Traditionally, for a slope reliability analysis, the supposed distribution types of shear strength parameters are employed; ... -
Upper Bound Analysis of 3D-Reinforced Slope Stability Subjected to Pore-Water Pressure
(ASCE, 4/1/2020 1)Pore-water pressure is a universal unfavorable external force and often poses an adverse impact on reinforced slope stability. Although recently the stability assessment of reinforced slopes has been extended to the ... -
Using Indirect Testing Methods to Quickly Acquire the Rock Strength and Rock Mass Classification in Tunnel Engineering
(ASCE, 5/1/2020 1)Uniaxial compressive strength (UCS) and tensile strength are essential parameters of rocks, but the direct measurement of these two parameters is time-consuming and requires high-quality samples. As such, academics brought ... -
Semianalytical Analysis of Creep and Thermal Consolidation Behaviors in Layered Saturated Clays
(ASCE, 4/1/2020 1)The creep and consolidation behavior of clays subjected to mechanical or thermal loads is of fundamental interest in the applications of energy piles, geothermal extraction, and geological waste disposal. This paper presents ... -
New Method to Evaluate Antiwashout Performance of Grout for Preventing Water-Inrush Disasters
(ASCE, 2/1/2020 1)Grouting is frequently used to prevent water-inrush disasters in tunnels and underground engineering. However, complex groundwater environment can significantly influence the grouting effect, especially the antiwashout ... -
Failure Mechanism of Two-Layered Slopes Subjected to the Surcharge Load
(ASCE, 2/1/2020 1)For some two-layered slopes subjected to the surcharge load, the soil mass undergoes rotational or translational movement. Thus, the conventional failure mechanism of homogeneous slopes is no longer applicable. To overcome ... -
Numerical Study of Liquefaction-Induced Uplift of Underground Structure
(ASCE, 2/1/2020 1)A finite-difference modeling was performed to investigate the liquefaction-induced uplift of an underground structure. The liquefaction-induced uplift of a 5 m diameter underground structure buried at a depth of ... -
New Method for Characterizing the Shear Damage of Natural Rock Joint Based on 3D Engraving and 3D Scanning
(ASCE, 2/1/2020 1)A lack of joint specimens with the same natural surface morphology has limited detailed experimental study of the shearing performances of joints. In this technical note, we propose a way to batch-produce rock joints with ... -
Study on Probabilistic Damage Constitutive Relation of Rocks Based on Maximum-Entropy Theory
(ASCE, 2/1/2020 1)The Weibull-distribution–based probabilistic damage model is widely used to represent the mesoscopic strength distribution of rock. However, it is unable to adequately describe the entire rock failure process. In this ... -
Upper-Bound Analysis for Soil Thrust of Single-Track System over Clay Ground
(ASCE, 2/1/2020 1)Soil thrust acts as a reaction force that enables an off-road tracked vehicle to overcome motion resistance and move the vehicle forward. Thus, the estimation of soil thrust for a track system has great importance in the ... -
Fast Door-Opening Method for Quick Release of Rock Boulder or Debris in Large-Scale Physical Model
(ASCE, 2/1/2020 1)Study on the mitigation of debris flows and rockfalls is a very challenging topic due to complex moving and impacting mechanisms. A large-scale physical model is preferred by researchers in the study of debris flow and ... -
Load Transfer Mechanisms of Granular Cushion between Column Foundation and Rigid Raft
(ASCE, 1/1/2020 1)The granular cushion has been increasingly used as a load transfer platform between a column foundation and a raft to ensure appropriate contact and load transfer among the raft, the columns, and the soil. However, deformation ... -
Modeling of Vehicle-Track-Tunnel-Soil System Considering the Dynamic Interaction between Twin Tunnels in a Poroelastic Half-Space
(ASCE, 1/1/2020 1)The vibration prediction of a vehicle-track-tunnel-soil dynamic system is quite meaningful in engineering practice. However, the complexity involved in modeling the underground environment makes most previous studies ignore ... -
Probabilistic Analysis of Step-Shaped Slopes Using Random Field Models
(ASCE, 1/1/2020 1)Step-shaped slopes are often found in mines. The reliability of step-shaped slopes was investigated based on random field models. The factor of safety of slopes was derived by the horizontal and vertical integration methods. ... -
Large-Scale True Triaxial Test on Stress-Strain and Strength Properties of Rockfill
(ASCE, 1/1/2020 1)Limited by the particle size requirements of testing apparatus, little true triaxial test (TTT) research on rockfill has been conducted. Using a large true triaxial apparatus (TTA) developed independently by the Changjiang ... -
Thermal Effects on Hydromechanical Response of Seabed-Supporting Hydrocarbon Pipelines
(ASCE, 2020)Subsea pipelines are commonly used for transportation of hot hydrocarbons from offshore sites. The temperature difference between the hot pipeline and the cold seabed induces thermal loads. Temperature effects on the ... -
