Influence of Salinity-Based Osmotic Suction on the Shear Strength of a Compacted Clay
(ASCE, 5/1/2021)As most previous studies have neglected the positive influence of salinity (osmotic suction) on most coastal soils in Australia, the design of transport infrastructure involving these soils has often been overly conservative. ... -
Constitutive Modeling for Two Sands under High Pressure
(ASCE, 5/1/2021)Particle breakage is a typical characteristic of crushable granular soil under high pressure, which has great effects on its stress–strain behaviors. The phenomenon of the critical state line (CSL) shifting downward in the ... -
Influence of Particle-Scale Properties on Fracture Behavior of Silica Sand
(ASCE, 5/1/2021)The distribution of stresses within individual granular particles subjected to one-dimensional (1D) confined compression is affected by various particle-scale properties, such as morphology, kinematics, position, crystal ... -
Expansion of Water Inrush Channel by Water Erosion and Seepage Force
(ASCE, 7/1/2021)Water and mud inrush is a common geological disaster in the construction of karst tunnels. The loss of soil particles in filling-type karst disaster-causing structures is the key factor leading to the expansion of the water ... -
Surface Settlement Control in the Excavation of a Shallow Intersection between a Double-Arched Tunnel and a Connection Tunnel
(ASCE, 4/1/2021)Ground surface settlement induced by shallow tunnel construction is inevitable, and it is more complicated at the intersection area since the rock behavior is a complex, three-dimensional problem. This paper presented a ... -
Nonlinear Viscoelastoplastic Fatigue Model for Natural Gypsum Rock Subjected to Various Cyclic Loading Conditions
(ASCE, 5/1/2021)To investigate its fatigue damage characteristics, natural gypsum rock was tested under multiple cyclic loading conditions. According to the fatigue test, a nonlinear viscoelastoplastic fatigue model was established by ... -
Shaking Table Tests to Evaluate the Seismic Performance of Soil Nailing Stabilized Embankments
(ASCE, 4/1/2021)A series of shaking table tests will be carried out on 0.4 m high instrumented soil nailed embankments. The important parameters considered in this study consist of a combination of three different slope angles (β = 30°, ... -
Peridynamics Simulation of Water Inrush Channels Evolution Process Due to Rock Mass Progressive Failure in Karst Tunnels
(ASCE, 4/1/2021)Water inrush is one of the most serious threats to the construction safety of karst tunnels. Numerical simulation is one of the important means of underground engineering research, which is of great significance for revealing ... -
New Viscoplastic Bounding Surface Subloading Model for Time-Dependent Behavior of Sands
(ASCE, 4/1/2021)This research focuses on experimental and constitutive time-dependent modeling of sands considering rate dependency, fabric, and stepwise sudden frequency changes during loadings. Several cyclic triaxial undrained tests ... -
Evaluation of Structural Strength and Parameters of Collapsible Loess
(ASCE, 6/1/2021)Loess is one of the problematic soils with a worldwide distribution for its collapsibility. To study structural strength and parameters of collapsible loess, a number of double-oedometer tests on intact and remolded loess ... -
Calibration of the Microparameters of Rock Specimens by Using Various Machine Learning Algorithms
(ASCE, 5/1/2021)High accuracy in the simulation of the discrete-element method (DEM) depends on the proper selection of microparameters. In this study, the range of microparameters was determined through sensitivity analysis. Subsequently, ... -
