Analytical Solutions for One-Dimensional Water Flow in Vegetated Layered Soil
(American Society of Civil Engineers, 2019)Vegetation reduces soil pore-water pressure (PWP) through root water uptake. There are limited studies about the effects of vegetation on PWP distributions in layered soil, such as multilayered earthen landfill cover. New ... -
Numerical Study for Compaction-Grouted Soil Nails with Multiple Grout Bulbs
(American Society of Civil Engineers, 2019)A finite-element model was adopted to numerically simulate compaction-grouted soil nails with multiple grout bulbs. The numerical model was first verified by the corresponding experimental results. Then a series of numerical ... -
Discrete and Continuum Numerical Modeling of Soil Arching between Piles
(American Society of Civil Engineers, 2019)The aim of this study was to investigate the soil-arching phenomenon between piles by adopting two different numerical methods: the discrete-element method and the finite-difference method. The discrete-element method, in ... -
Combining Microtomography, 3D Printing, and Numerical Simulations to Study Scale Effects on the Permeability of Porous Media
(American Society of Civil Engineers, 2019)The analysis of the geometry of porous media is an important aspect of modern soil sciences. This comes from the fact that not only experimental studies but also numerical simulations demand a considerable knowledge of the ... -
Stability and Deformation Analysis for Geotechnical Problems with Nonassociated Plasticity Based on Second-Order Cone Programming
(American Society of Civil Engineers, 2019)The second-order cone programming (SOCP) optimized FEM (named FEM-SOCP) is extended to solve the geotechnical problems involving nonassociated plasticity. When FEM-SOCP is used with strength reduction, FEM-SOCP generally ... -
Evaluation of Permanent Settlement in Hangzhou Qingchun Road Crossing-River Tunnel under Traffic Loading

Volumetric Behavior and Soil Water Characteristic Curve of Untreated and Lime-Stabilized Reactive Clay
(American Society of Civil Engineers, 2019)This paper investigates the influence of lime stabilization of an expansive clay based on volumetric behavior and the soil–water characteristic curve (SWCC). The selected soil was a residual clay located in Victoria, ... -
Evaluating Damage and Microcracking Behavior of Granite Using NMR Testing under Different Levels of Unconfined Compression
(American Society of Civil Engineers, 2019)This work discusses the results from tests performed to investigate the damage and microcracking behaviors of granites. The samples, previously loaded to varying predefined stress levels and then unloaded to zero, were ... -
Preliminary Experimental Study of Effect of CO<sub>2</sub>-H<sub>2</sub>O Biphasic Fluid on Mechanical Behavior of Sandstone under True Triaxial Compression
(American Society of Civil Engineers, 2019)Understanding the mechanical behavior of a reservoir is essential for securing the safety of CO2 storage projects. In this study, the effect of CO2-H2O biphasic fluid on the mechanical behavior and failure characteristics ... -
A Formulation for Estimating the Compression of Fibrous Peat Using Three Parameters
(American Society of Civil Engineers, 2019)High variability in the results of laboratory tests with peat poses difficulties in the application of the classic consolidation theory to the prediction of settlement in the field. This article presents a formulation ... -
Analytical Solution for Estimating the Stress State in Backfill Considering Patterns of Stress Distribution
(American Society of Civil Engineers, 2019)Large underground voids created by removal of ore are usually backfilled with mill tailings. The stress state in the backfill must be estimated to ensure safety. Most of the existing analytical solutions for estimating ... -
Comparison of Modeling Soil Parameters Using Random Variables and Random Fields in Reliability Analysis of Tunnel Face
