Shear Modulus and Damping Ratio Model for Cement Treated Clay
(American Society of Civil Engineers, 2019)A hyperbolic model-based normalized shear modulus reduction (G/Gmax) formulation for cement treated clay is presented. This three-parameter normalized shear modulus reduction model can be constructed using maximum shear ... -
Moisture Hysteretic Behavior of Fine-Grained Soils Stabilized with Lime and Class C Fly Ash
(American Society of Civil Engineers, 2019)Seasonal conditions (e.g., rise in the water table, precipitation, freeze–thaw cycles, and wet–dry cycles) affect stabilized subgrade moisture conditions which, in turn, have a significant impact on in-service pavement ... -
Prediction of Resilient Modulus of Compacted Cohesive Soils in South China
(American Society of Civil Engineers, 2019)The resilient modulus has been used to characterize the stress–strain nonlinear behavior of subgrade soils and is the primary property needed for pavement design and analysis. The degrees of stress and moisture content ... -
Estimation of Active Earth Pressure on Inclined Retaining Wall Based on Simplified Principal Stress Trajectory Method
(American Society of Civil Engineers, 2019)Because of the existence of wall-soil friction behind retaining wall, the transfer direction of the principal stress will be inevitably changed. Therefore, the arching effect of soil mass is considered and the circle ... -
Panel Data Models for Pavement Friction of Major Preventive Maintenance Treatments
(American Society of Civil Engineers, 2019)Although accurate evaluation of pavement friction promises significant safety benefits to highway agencies, the development of such models has proven to be challenging due to the lack of complete and quality pavement surface ... -
Wetting Deformation of Core-Wall Rockfill Dams
(American Society of Civil Engineers, 2019)In this study, a new wetting deformation simulation method for core-wall rockfill dams is proposed based on a wetting model that considers the upstream damming rockfill as softening materials when they are immersed and ... -
Elastoplastic Solutions for Surrounding Rock Masses of Deep-Buried Circular Tunnels with Non-Darcian Flow
(American Society of Civil Engineers, 2019)The significant characteristics of the non-Darcian flow of groundwater seepage in a low-permeability rock mass have been reported, but there have been few studies on the analytical solutions for deep-buried circular tunnels ... -
3D Nonlinear Analysis of Atatürk Clay Core Rockfill Dam Considering Settlement Monitoring
(American Society of Civil Engineers, 2019)One of the most important causes of damages in clay core rockfill (CCR) dams is the deterioration of the rockfill material over time and big settlements in the dam body. Therefore, the forecast of the settlements and ... -
Analytical and Experimental Study of Cemented Backfill and Pillar Interactions
(American Society of Civil Engineers, 2019)Massive voids form in underground mines due to the continuous removal of valuable minerals. Backfill and pillars are commonly built into the voids to provide both local and regional support. The backfill material cannot ... -
Application of DSC Model for Natural-Element Analysis of Pile Foundations under Cyclic Loading
(American Society of Civil Engineers, 2019)The present paper is about the application of the disturbed-state concept (DSC) model and a mesh-free method called the natural-element method (NEM) for analyzing the dynamic response of pile foundations. In comparison to ... -
Identification and Location Method of Microseismic Event Based on Improved STA/LTA Algorithm and Four-Cell-Square-Array in Plane Algorithm
(American Society of Civil Engineers, 2019)The key issue of microseismic (MS) monitoring technology is to detect MS events and accurately locate the MS source. On the basis of the traditional short-term average/long-term average (STA/LTA) algorithm, a new characteristic ... -
Predicted Behavior of Saturated Granular Waste Blended with Rubber Crumbs
(American Society of Civil Engineers, 2019)Recycling waste materials, such as steel furnace slag (SFS), coal wash (CW), and rubber crumbs (RC) for transport infrastructure is environmentally friendly and offers significant economic benefits. This paper presents a ... -
3D Modeling of Long-Term Dynamic Behavior of Monopile-Supported Offshore Wind Turbine in Clay
(American Society of Civil Engineers, 2019)This article outlines the long-term dynamic behavior of the monopile-supported offshore wind turbine (OWT) in clay. A three-dimensional (3D) finite-element (FE) model was developed that uses viscoelastic material constitutive ... -
Seismic Displacement of 3D Slope Reinforced by Piles with Nonlinear Failure Criterion
(American Society of Civil Engineers, 2019)The seismic displacement estimation of soil slopes was generally focused on the plane strain assumption with a linear Mohr-Coulomb failure criterion. In engineering, slope stability often becomes more of a three-dimensional ... -
