Seismic Ultimate Bearing Capacity of a Hoek-Brown Rock Slope Using Discretization-Based Kinematic Analysis and Pseudodynamic Methods
(American Society of Civil Engineers, 2018)This study presents a novel procedure for predicting rock slope stability in the presence of an earthquake by using pseudodynamic and discretization-based kinematic analysis methods. In contrast to a presumed failure ... -
Analysis of Characteristic Frequencies of Coupled Soil-Pile-Structure Systems
(American Society of Civil Engineers, 2018)A combination of the multiple-shear-spring soil model and a rigorous soil-pile interaction spring was implemented through a finite-element computer code to ascertain characteristic frequencies dominating the nonlinear ... -
Numerical Assessment of Equivalent Radius for Electrokinetic Geosynthetics Electrodes during Electroosmotic Consolidation
(American Society of Civil Engineers, 2018)Electrokinetic geosynthetics (EKG) has been used as an electrode to perform electroosmotic consolidation for the improvement of soft soil. To use previous analytical theories to analyze the drainage and consolidation ... -
Theoretical Analysis of Torsional Wave Propagation in a Heterogeneous Aeolotropic Stratum over a Voigt-Type Viscoelastic Half-Space
(American Society of Civil Engineers, 2018)The aim of this paper was to study the analytical problem of torsional surface wave propagation in an initially stressed heterogeneous aeolotropic layer over a Voigt-type viscoelastic half-space. It is known that an elastic ... -
Efficient Scaled-Boundary Radial Point Interpolation Method for Unsteady Confined-Seepage Flow through Nonhomogeneous and Anisotropic Soils
(American Society of Civil Engineers, 2018)The two-dimensional unsteady confined-seepage flow through nonhomogeneous and anisotropic soils is studied in this paper. The study was based on a novel semianalytical method called scaled-boundary radial point interpolation ... -
Rock-Cutting Mechanics Model and Its Application Based on Slip-Line Theory
(American Society of Civil Engineers, 2018)Rock mechanics parameters for underground engineering cannot be rapidly or comprehensively tested on site; thus, this article presents a method for determining rock mechanics parameters using drilling parameters obtained ... -
Modeling of Permeability in Stratified Sands Using a Wave-Propagation Method
(American Society of Civil Engineers, 2018)Layered soils are often encountered in nature; hence, it is important to determine the coefficient of permeability in them, due to its effect on ground contamination and the recharging of water basins. While porosity–permeability ... -
Mechanical Properties of Strongly Weathered Rock–Soil Mixtures with Different Rock Block Contents
(American Society of Civil Engineers, 2018)Although soil–rock mixtures (S-RMs) exist extensively on Earth’s surface, their mechanical behaviors remain elusive. In this study, a series of large-scale direct-shear tests was conducted to investigate the mechanical ... -
Fracturing Behavior and Failure in Hollowed Granite Rock with Static Compression and Coupled Static–Dynamic Loads
(American Society of Civil Engineers, 2018)Underground excavation is often observed to be cut by induced fractures and, occasionally, collapses violently with the generation of a shear fracture throughout the opening. To study the development of these and other ... -
Soil Arch Effect Analysis of Shield Tunnel in Dry Sandy Ground
(American Society of Civil Engineers, 2018)During shield tunneling, the soil arching effect in front of the excavation face can effectively reduce the impact of excavation on the surrounding environment. This effect was studied with different depth/diameter ratios ... -
Hyperstatic Reaction Method for the Design of U-Shaped Tunnel Supports
(American Society of Civil Engineers, 2018)This paper presents a numerical hyperstatic reaction method (HRM) for analyzing U-shaped (with inverted arch) tunnel structures. A comparison of the results obtained from two different load conditions, i.e., with and without ... -
Reliability Analysis of Tunnel Face in Broken Soft Rocks Using Improved Response Surface Method
(American Society of Civil Engineers, 2018)An improved response surface method (RSM) is presented for reliability analysis of a tunnel face in broken soft rocks. To fully consider the variation of the slip surface caused by the random variables in the process of ... -
Coupled DEM and FDM Algorithm for Geotechnical Analysis
(American Society of Civil Engineers, 2018)The purpose of this paper is to present a new algorithm for coupling discrete-element and finite-difference methods for three-dimensional problems. The finite-difference method (FDM) and the discrete-element method (DEM) ... -
Influence of Passively Loaded Piles on Excavation-Induced Diaphragm Wall Displacements and Ground Settlements
(American Society of Civil Engineers, 2018)Deep excavations in congested urbanized areas may have a significant impact on existing structures. Therefore, protective measures must be taken to control wall deformations and related soil movements. However, little is ... -
Statistical Evaluation of the Load-Settlement Response of a Multicolumn Composite Foundation
(American Society of Civil Engineers, 2018)This study examined a composite foundation that was improved by the joint usage of two types of columns: soil-cement and stone columns. The composite foundation that consists of soil-cement columns, stone columns, and ... -
Evaluation and Analysis of the Traffic Load–Induced Settlement of Roads on Soft Subsoils with Low Embankments
