Case History Evaluation of the Behaviour of Drilled Shafts Under Axial and Lateral Loading
This report presents the results of a study to evaluate drilled shaft behavior under axial and lateral loading for undrained and drained conditions. This is a critical evaluation that incorporates a wide variety of available field and laboratory load test data, standardized to a consistent reference plane. It gives specific design recommendations for drilled shafts and the appropriate statistics to describe the quality of the recommendations.
As a result of gravity dead loads, vertical live loads such as ice and snow accumulations and lateral wind loads, the design of foundations for transmission line structures is dominated by axial and lateral loading. A variety of analytical models and load test databases have led to differences and perception of drilled shaft behavior under these loading modes and a consistent design methodology does not exist for those foundations. As a result, engineers often recommend drilled shafts having significantly different dimensions for identical geotechnical and loading conditions.

This book is about the mechanics of soils and structures interacting with soils. It has been primarily designed as a classroom teaching book, but it also covers more advanced aspects, usually included in upper level courses on civil and geotechnical engineering.
The behaviour of soil is today approached on sound and rational bases, using concepts of continuum mechanics, and experimental evidences prove that it is a significant and powerful procedure.
Soils are natural materials and the solution of engineering problems requires the knowledge of the properties of real soils. These properties have to be investigated, rather then being prescribed, so that it is necessary to be familiar with testing techniques and to be aware of the relevance of field investigation.
However, both phases of programming and interpreting experimental tests require a conceptual framework, and for this reason reference has been made throughout this book to the Critical State Theory. The central idea of this theory is that volume changes play a role so important as the effective stresses and it is the relation between the initial
state and the critical state that has a major influence on soil behaviour. Moreover, this theory also provides a link between soil mechanics and previously grasped concepts as elasticity and plasticity, that in turn are extensively used in two final chapters, aimed at applications.

In this book the mathematical complications of calculating stability, damage, strain localization and size effect in order to predict response of structural components under a variety of environmental conditions are explored. The development of continuum-based models for failure enriched with micro-structural information and models capable of tracing the entire lifetime of constructions and structures are also considered.

Develop a better understanding of what causes environmental problems and how to solve them! Today, engineers and scientists must work on more complex environmental problems than ever before. To find solutions to these problems requires an in-depth knowledge of the fundamentals of chemistry, biology, and physical processes. This text will provide you with a clear explanation of these fundamentals that are necessary for solving both small town and global environmental problems. With Fundamentals of Environmental Engineering, you'll develop a better understanding of the key concepts required for design, operation, analysis, and modeling of both natural and engineered systems. You'll also be able to make connections among the different specialty areas of environmental engineering emphasized throughout the text. And you'll quickly learn how to solve complex environmental problems and incorporate environmental concerns into your specialty. Key Features
* Covers the fundamentals of chemical, physical, and biological processes, and various units of concentration as applied to environmental engineering.
* Includes applications related to drinking water and wastewater treatment, air quality engineering and science, groundwater transport and remediation, surface water quality, hazardous solid waste management, and ecosystems.
* Developed by a team of authors who specialize in a diverse set of environmental areas.
Important Comment: Great book for those just starting to learn about the field!
This book teaches the fundamentals of Environmental Engineering in a way that everybody can understand. It's well written and well layed out. Great examples help to clarify and expand on points made in the text. The figures and tables also improve on the students learning ability as they progress through the book. All in all an excellent book for the beginning Environmental Engineer as well as a handy companion for the Engineer already out in the field. Dr. Mihelcic is an excellent author along with all the other professors who helped out.

GIS technology is increasingly used in water resources engineering in a variety of ways. This book provides a fundamental understanding of GIS, including how to develop and analyze geographic data, how to differentiate between the various types of geographic data, and how to assess the operational requirements needed to implement GIS. With an introduction to primary remote sensing as well as methods of interpretation and analysis, the text focuses on how GIS data can be applied to water resource analysis models. Such applications include water supply demand forecasting, hydrologic modeling watersheds, modeling erosion, and non-point sources of water pollution.
