Investigating the Optimized Open V-Shaped Trench Performance in Reduction of Train-Induced Ground Vibrations
(American Society of Civil Engineers, 2014)An effective strategy in reducing train-induced vibrations on neighboring structures is to use open trenches on both sides of the railway lines. This paper investigates the effect of the trench’s shape on its performance. ... -
Simulated Radial Expansion and Heave Caused by Compaction Grouting in Noncohesive Soils
(American Society of Civil Engineers, 2015)Compaction grouting is widely used for ground improvement, including foundation retrofitting, earthquake disaster mitigation, and settlement compensation. However, until now, it has been developed and used based on an ... -
Bearing Capacity of Strip Footings in Cohesionless Soil Subject to Eccentric and Inclined Loads
(American Society of Civil Engineers, 2014)Lower-bound calculations based on the FEM are used to determine the bearing capacity of a strip foundation subjected to an inclined, eccentric load on cohesionless soil with varying surcharges and with friction angles of ... -
Approximate Solution to the Sokolovskiĭ Concave Slope at Limiting Equilibrium
(American Society of Civil Engineers, 2015)The growth of precision autoguidance systems on construction equipment suggests that nonplanar slopes and landforms now can be constructed readily. Slopes with concave cross sections not only appear more like natural slopes, ... -
Generalized Solution for Mining Backfill Design
(American Society of Civil Engineers, 2014)Underground backfill plays an important role in the mining industry, and is one of the key elements in the routine operation of many underground mines. Its main role is to improve ground stability and reduce ore dilution. ... -
Cyclic Elastoviscoplastic Constitutive Model for Clay Considering Nonlinear Kinematic Hardening Rules and Structural Degradation
(American Society of Civil Engineers, 2015)A cyclic elastoviscoplastic constitutive model for clayey soils is proposed based on the nonlinear kinematic hardening rules and considering the structural degradation. The performance of the model is verified through the ... -
Estimation of Slope Stability Using Two-Parameter Criterion of Stability
(American Society of Civil Engineers, 2014)Modern methods for calculating slope stability in current finite-element programs involve the stepwise uniform reduction of the soil strength parameters. However, prediction of the strength-reduction law under the influence ... -
Discrete Element Simulations of Cyclic Biaxial Shear of a Granular Material with Oval Particles
(American Society of Civil Engineers, 2014)Discrete element method (DEM) simulations are used for measuring the macroscale and microscale changes in stress and fabric for the cyclic loading of a two-dimensional granular assembly. The stress–strain–dilatancy tendencies ... -
Numerical Solution of Single Pile Subjected to Simultaneous Torsional and Axial Loads
(American Society of Civil Engineers, 2014)Torsional loads on pile foundations are induced by the action of eccentric horizontal forces on the supporting structures. Such loading not only initiates twisting at the pile head but also reduces its axial capacity ... -
Torsional Wave Propagation in a Substratum over a Dry Sandy Gibson Half-Space
(American Society of Civil Engineers, 2014)The propagation of torsional surface waves in a transversely isotropic substratum lying over a dry sandy gibson half-space in the presence of initial stress (compressive and tensile) and gravity have been studied analytically ... -
Artificial Neural Networks for Modeling Drained Monotonic Behavior of Rockfill Materials
(American Society of Civil Engineers, 2014)In this paper, the feasibility of developing and using artificial neural networks (ANNs) for modeling the monotonic behaviors of various angular and rounded rockfill materials is investigated. The database used for development ... -
Behavior of Laterally Loaded Piles in Multilayered Soils
(American Society of Civil Engineers, 2015)Piles have been widely used to resist lateral loads in geotechnical engineering. In reality, piles are always embedded in layered soils; however, theoretical solutions for laterally loaded piles in multilayered soil system ... -

Vertical Stress Isobars for Trenches and Mine Stopes Containing Granular Backfills
(American Society of Civil Engineers, 2014)The vertical stresses within granular fills contained in trenches can be determined using Marston’s theory or numerical modeling. Marston’s theory gives only the average value of the vertical stress at a depth. Numerical ... -
