Analysis of Dynamic Laterally Loaded Pile in Clay
Deflections of laterally loaded pile groups are strongly affected by the degree of pile head fixity. If the cap provides perfect restraint against rotation, deflections are only about...
Making the Grade
Adding two lanes to a stretch of highway in western Colorado required excavation on slopes and involved micropiles, mechanically stabilized earth walls, ground anchors, and soil nails....
Headcut Analysis for Off-Channel Gravel Pits in Arid Environments
The study focuses on a large gravel pit located adjacent to the Santa Cruz River between the confluences with the Rillito and Canada del Oro rivers in Tucson, Arizona. These gravel pits...
Estimating the Return Period of Multiyear Droughts
Characterizing the return period of hydrologic events has been an important subject in water resources planning and management studies for many decades. The alternative approach has been...
Optimal Selection of Rechlorinization Station in Water Distribution System by Optimization Techniques
The optimal rechlorination in water distribution systems was investigated by incorporating optimization techniques into a numerical water quality model (EPANET2). Four types of optimization...
Evaluation of Anchor Wall Systems' Landmark Reinforced Soil Wall System
With T.C. Mirafi's Miragrid & Miratex Geogrid Reinforcement ?Final Report
This report describes a HITEC evaluation designed to determine the basic capability and limitations of the Landmark/Mirafi System for use as a technically viable precast MSE retaining...
Evaluation of the CON-ARCH reinforced Concrete Buried Arch System
Final Report
This report summarizes the evaluation of the Con-Arch culvert system marketed by Hunter Contracting, Co. of Tucson, Arizona. The evaluation consisted of computer analysis and field testing of two Con-Arch...
Overview of Long-Span Bridge Assessment History
This section gives a brief overview of long-span bridge assessment history. Also included are a few cases of long-span bridge failure and lack of assessment....
Introduction
Historically, animal waste was considered a valuable fertilizer and thus land was applied for sustainable on-farm production of crops and animals. However, with the shift to large production...
Seepage and Transport through Anaerobic Lagoon Liners
In this chapter, the seepage and transport characteristics of lagoon liners are addressed using the soils and hydrogeology of southwest Kansas as examples....
Analysis
This chapter presents a brief overview of the current analytical modeling techniques for isolated structures. Perhaps the biggest challenge in the design of an isolated structure is incorporating...
Constructing on the Inconstructible
Exhaustive and sophisticated analyses of extremely weak foundation soils coupled with an innovative approach to quay wall design help bring the new shipping terminal under construction...
State of the Art of Structural Engineering
The objective of this paper is to provide an overview of the developments in structural engineering that took place during the past century. This overview includes: (1) some of the major...
Forensics and Case Studies in Civil Engineering Education: State of the Art
This paper reviews the state of the art in the use of forensic engineering and failure case studies in civil engineering education. The study of engineering failures can offer students...
Review of Stabilization of Clays and Expansive Soils in Pavements and Lightly Loaded Structures�History, Practice, and Future
Expansive clay soils�those that change significantly in volume with changes in water content�are the cause of distortions to structures that cost taxpayers several billion dollars annually...
Impact of Chemically-Induced Clay Transport and Deposition on the Hydraulic Conductivity of a Natural Sand
The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims:...
Rate of Under-Registration Due to Failures of Large Meters
Leaks and meter under registrations are suspected as primary components of unaccounted-for water in Korea. In 2001, national unaccounted-for-water rate is reported as 26.6%. More than...
Thermal Cyclone Washing for Remediation of Petroleum Contaminated Soils
Thermal Cyclone Washing (TCW) is a soil remediation technology developed and tested at the University of Alabama in Huntsville. TCW is a combination of thermal, chemical, and physical...
Bayesian Approach to Support Design of a Groundwater Long Term Monitoring Plan
