Influence of Particle Breakage on Critical State Line of Rockfill Material
(American Society of Civil Engineers, 2016)The influences of particle breakage on the position of the critical state line (CSL) were systematically investigated in this paper through a series of large-scale triaxial compression tests on Tacheng rockfill material ... -
Love-Type Wave Propagation in an Irregular Prestressed Composite Sandwiched Layer
(American Society of Civil Engineers, 2016)The present problem analytically investigates the possibility of Love-type wave propagation in a prestressed irregular composite layer lying between an upper prestressed heterogeneous isotropic layer of finite width and a ... -
One-Dimensional Coupled Infiltration and Deformation in Unsaturated Soils Subjected to Varying Rainfall
(American Society of Civil Engineers, 2016)Assuming that the water content and hydraulic conductivity of unsaturated soil are exponential functions of the pressure head, Green’s function is used to obtain analytical solutions to one-dimensional coupled rainfall ... -
Bounding Surface Constitutive Model for Cemented Sand under Monotonic Loading
(American Society of Civil Engineers, 2016)This paper presents a critical state constitutive model for cemented sand. The model uses a single capped yield surface as a function of the void ratio, confining pressure, preconsolidation pressure, and stress ratio at ... -
Numerical Simulation Analysis of Reservoir Bank Fractured Rock-Slope Deformation and Failure Processes
(American Society of Civil Engineers, 2016)The fluctuations of reservoir water levels significantly change the hydrogeological conditions of reservoir banks and thus affect the steady state of the bank slope. Reservoir landslide stability is governed by the complex ... -
Evaluation Approach of the Slope Stability Based on Deformation Analysis
(American Society of Civil Engineers, 2016)Once a slope is led to the limit equilibrium state using the strength-reduction method, the displacement contours located near the critical slip surface are quite close. The critical slip surface is composed of the points ... -
Three-Dimensional Slope Stability Charts for Frictional Fill Materials Placed on Purely Cohesive Clay
(American Society of Civil Engineers, 2016)This paper investigates slope stability and produces a set of stability charts for three-dimensional (3D) slopes for a specific case in which frictional fill materials are placed on purely cohesive clay. As slopes are not ... -
Pressure Distribution around Rigid Culverts Considering Soil–Structure Interaction Effects
(American Society of Civil Engineers, 2016)Heger pressure distributions are considered a fundamental tool in the design of RC culverts, according to the direct-design method. However, some factors known to affect soil–structure interaction are neglected when using ... -
Drained Instability in Loose Granular Material
(American Society of Civil Engineers, 2016)The constant shear drained (CSD) test is considered an appropriate test to simulate the instability behavior of soils in slopes under water infiltration conditions or lateral stress relief. However, contradiction of the ... -
Axially Loaded Piles in Consolidating Layered Soil
(American Society of Civil Engineers, 2016)The interaction of an applied axial load and a drag load on a circular pile in consolidating layered soil is investigated. A rigorous load-transfer theory with elastoplastic slip considered at the pile–soil interface for ... -
Observed Effects of Interparticle Friction and Particle Size on Shear Behavior of Granular Materials
(American Society of Civil Engineers, 2016)This paper presents an experimental study on the shear behavior of granular materials, focusing on the effects of interparticle friction and particle size, which are of fundamental importance but are not yet well understood. ... -
Case Studies of Reinforced Piled High-Speed Railway Embankment over Soft Soils
(American Society of Civil Engineers, 2016)Soil arching in the reinforced piled embankment is investigated in this paper on the basis of two case studies of high-speed railways constructed in the eastern coastal region of China. The majority of the overburden load ... -
Uplift Capacity of Plate Anchors in Saturated Clays: Analyses with Different Constitutive Models
(American Society of Civil Engineers, 2016)Evaluation of the uplift capacity of plate anchors in saturated clay is an important aspect in the design of offshore foundation systems of various structures. In most of the literature reviewed, simple constitutive models ... -
Effect of Granular-Column Installation on Excess Pore Pressure Variation during Soil Liquefaction
(American Society of Civil Engineers, 2016)During many earthquakes, soil liquefaction causes dramatic damage. The use of a granular column is a ground-improvement technique used to mitigate soil liquefaction. The present paper studies the performance of reinforcement ... -
Parameter Study of a New Strut-and-Tie Model for a Thick Cap with Six Piles
(American Society of Civil Engineers, 2016)A comprehensive strut-and-tie model is a function of the nodes, struts, ties, model types, and pile reaction force. Because each element has more than one solution, the function is a problem of permutations and combinations. ... -
Prediction of Safe Bearing Capacity of Noncohesive Soil in Arid Zone Using Artificial Neural Networks
(American Society of Civil Engineers, 2016)Estimation of safe bearing capacity (SBC) of noncohesive soil based on Indian Standard Code requires a lot of field work, viz, conducting direct shear tests to determine cohesion and angle of internal friction, performing ... -
