Assessment of Core-Filter Configuration Performance of Rock-Fill Dams under Uncertainties
(American Society of Civil Engineers, 2018)Probabilistic analyses are conducted for seepage through a rock-fill dam having two different core-filter configurations: one sloping and the other a central symmetrical core-filter arrangement. Uncertainties in core and ... -
Validation Tests for Discrete Element Codes Using Single-Contact Systems
(American Society of Civil Engineers, 2018)In recent years, the discrete element method (DEM) has become widely used to solve a number of geological and geophysical problems. The basic idea of this method is to consider rock-soil bodies, in their discontinuous ... -
Decoupled Advection-Dispersion Method for Determining Wall Thickness of Slurry Trench Cutoff Walls
(American Society of Civil Engineers, 2018)Low-permeability slurry trench cutoff walls are commonly constructed as barriers for containment of subsurface point-source pollution or as part of seepage-control systems on contaminated sites. A method to estimate wall ... -
Scattering of Plane SH Waves Induced by a Semicylindrical Canyon with a Subsurface Circular Lined Tunnel
(American Society of Civil Engineers, 2018)An analytical study of multiple scattering of plane shear horizontal (SH) waves induced by a semicylindrical canyon and a nearby buried circular lined tunnel in a homogeneous elastic half-space is presented using the ... -
Development of a New Correlation to Estimate the Unconfined Compressive Strength of a Chicontepec Formation
(American Society of Civil Engineers, 2018)The Chicontepec Formation is a complex and heterogeneous calcitric-lithic sandstone reservoir with significant historical problems of borehole collapse. To predict and mitigate the subsurface issues, it is essential to ... -
Numerical Analysis of MSW Effects on Interface Behavior of Lined Landfill System
(American Society of Civil Engineers, 2018)In this study, the role of municipal solid waste (MSW) behavior in the stress-deformation response of interfaces in a lined landfill system was assessed. MSW was modeled using a constitutive model that considers its ... -
Case Study of a Collapse Investigation of Loess Sites Covered by Very Thick Loess–Paleosol Interbedded Strata
(American Society of Civil Engineers, 2018)Young loess deposits are the most well-known collapsible soils because of their small unit masses, high void ratios, and open metastable structures. Properly assessing the collapse of loess sites covered by very thick ... -
Incorporating Hydromechanical Coupling of Unsaturated Soils into the Analysis of Rainwater-Induced Groundwater Ponding
(American Society of Civil Engineers, 2018)The moisture contents and coefficients of permeability of partially saturated soils are assumed to follow an exponential function of the pressure head. A partial differential equation is proposed here to describe the ... -
Performance and Three-Dimensional Analyses of a Wide Excavation in Soft Soil with Strut-Free Retaining System
(American Society of Civil Engineers, 2018)This paper presents the results of monitoring the diaphragm wall and ground surface settlement and three-dimensional finite element analyses of the Xizhi excavation case history. The Xizhi excavation was 9.2 m deep, covering ... -
Ground Control Monitoring in Backfilled Strip Mining under the Metropolitan District: Case Study
(American Society of Civil Engineers, 2018)Ground subsidence and coal gangue induced by mining activities could significantly influence the nearby environment. To allow strict public scrutiny of mining under the metropolitan district, coal gangue backfill has been ... -
New Perspective on Seismic Slope Stability Analysis
(American Society of Civil Engineers, 2018)This article proposes a graphical method associated with the g line to evaluate seismic slope stability. The g line depicts the combinations of c/γH and tanφ that are necessary to maintain slope stability at the critical ... -
Postconstruction Settlement Prediction of High Embankment of Silty Clay at Chengde Airport Based on One-Dimensional Creep Analytical Method: Case Study
