Deep Penetration of Strip and Circular Footings into Layered Clays
(American Society of Civil Engineers, 2002)The bearing behavior of footings on layered soils has received significant attention from researchers, but most of the reported studies are limited to footings resting on the surface of the soil and are based on the ... -
Strains Preceding Failure in Infinite Slopes
(American Society of Civil Engineers, 2002)An analysis is presented of the strains and displacements that take place in an infinite slope, consisting of an elastic‐plastic Mohr‐Coulomb material, due to the increase of the water table level. In particular, an attempt ... -
A Theoretical Solution for Consolidation Rates of Stone Column‐Reinforced Foundations Accounting for Smear and Well Resistance Effects
(American Society of Civil Engineers, 2002)Theoretical and experimental studies have proven that stone columns can be used for accelerating the consolidation rate of soft soil by providing a drainage path and reducing stresses in the soil. In constructing stone ... -
Behavior of Piled Raft Foundations Under Lateral and Vertical Loading
(American Society of Civil Engineers, 2002)This article presents a new method of analysis of piled raft foundations in contact with the soil surface. The soil is divided into multiple horizontal layers depending on the accuracy of solution required and each layer ... -
Static Response of Reinforced Soil Retaining Walls with Nonuniform Reinforcement
(American Society of Civil Engineers, 2001)The structural response of reinforced‐soil wall systems with more than one reinforcement type (nonuniform reinforcement) is investigated using a numerical approach. The selected reinforcement types and mechanical properties ... -
Recurrent and Constructive‐Algorithm Networks For Sand Behavior Modeling
(American Society of Civil Engineers, 2001)This article presents and discusses various aspects regarding the modeling of the behavior of a coarse granular material using Recurrent Neural Networks (RNNs) and Constructive Algorithms (CAs). A series of undrained ... -
Reliability Analysis in Geotechnics with Deterministic Finite Elements — Theoretical Concepts and Practical Application
(American Society of Civil Engineers, 2001)A comprehensive procedure for combining probabilistic concepts and deterministic finite element methods for geotechnical analysis is presented. Bayes’ theorem is employed to arrive at input parameters for the calculations ... -
An Experimental and Numerical Study of the Low‐Pressure Grouting of Granular Soils by Diluted Chemical Solutions
(American Society of Civil Engineers, 2001)The use of silicate solutions for the low‐pressure grouting of granular soils is one of the techniques applicable in geotechnical engineering to reduce the “natural” hydraulic conductivity of granular deposits. This provision ... -
Forward and Inverse Models for Parameter Identification of Layered Media
(American Society of Civil Engineers, 2001)This article presents a newly developed parameter identification procedure for layered media and in particular for pavement structures via the use of the Falling Weight Deflectometer (FWD) test. Emphasis is placed on the ... -
Estimation of Footing Settlement in Sand
(American Society of Civil Engineers, 2002)The settlement of foundations under working load conditions is an important design consideration. Well‐designed foundations induce stress‐strain states in the soil that are neither in the linear elastic range nor in the ... -
Land Subsidence Spreading Factor of the Northern Adriatic Gas Fields, Italy
(American Society of Civil Engineers, 2001)The land subsidence spreading factor χ provides a useful straightforward indication on how much of a gas/oil reservoir compaction induced by field development migrates to ground surface with a possible adverse impact on ... -
Development of a New Structural Model with Prism and Strip Elements for Pavements on Steel Bridge Decks
(American Society of Civil Engineers, 2001)A new structural model for pavements on steel bridge decks (SLPE) is developed. In this model, a prism element and a strip element represent the pavement and steel bridge deck, respectively. A newly developed link element ... -
