Soil Factors Determining the Wear of Soil Cutting Working Tools
Author: Wear of Rock Cutting Tools
Author: P.N.W. VerhoefPublisher: Routledge
ISBN: 1351404652
Category : Technology & Engineering
Languages : en
Pages : 302
Book Description
This text deals with the dredging of rock by large cutter suction dredgers. The rock properties influencing the mechanical cutting of rock and the wear of cutting teeth are examined, and to verify the model of mechanical rock excavation developed, case studies of dredging projects were performed.

Soil Cutting and Tillage
Author: E. McKyesPublisher: Elsevier
ISBN: 044460104X
Category : Technology & Engineering
Languages : en
Pages : 226
Book Description
After giving a brief history of tillage practices and implements used throughout the world dating back to ancient times, this book goes on to describe the basic soil mechanics techniques needed to calculate the forces developed in soil by simple-shaped cutting tools. The methods of measuring soil mechanical properties, water pressure in soil and shear rate effects are touched upon. A review is given of two and three dimensional soil cutting mathematical mechanics models to predict soil cutting forces and soil volumes disturbed by cutting and tillage tools, as well as the state-of-the-art of soil loosening, structural rearrangement and plant growth as affected by tillage tools. The author also includes an introduction to the analysis of traction machines. There are many numerical examples of mechanical analyses and predictions worked out in the various sections of the book as well as numerous unsolved problems at the end of a number of the chapters.Written in a textbook style, this monograph is ideal for anyone wanting to learn modern techniques for the mechanical description of soil cutting and tillage forces and soil volumes disturbed. It also provides a reference for analytical formulae and calculated force forces. It will be of interest to universities and colleges worldwide which have Agricultural Engineering Programs, Civil and Mechanical Engineering schools which specialize in soil mechanics and construction machinery as well as to research stations worldwide with interests in soil tillage, soil physics etc.

Engineering Geology for Society and Territory - Volume 6
Author: Giorgio LollinoPublisher: Springer
ISBN: 3319090607
Category : Science
Languages : en
Pages : 1003
Book Description
This book is one out of 8 IAEG XII Congress volumes, and deals with the theme of applied geology, which is a critical theme for the global economy. In the international, multidisciplinary approach to major engineering projects (either to macro- or mega-scale), the application of geological investigation techniques is fundamental for properly selecting the location sites, planning the construction and maintaining the infrastructures. The contributions in this book include not only engineering constructions but also case studies related to large projects on geo-resources exploration and extraction (minerals, petroleum and groundwater), energy production (hydropower, geothermal, nuclear and others), transportation (railway and highway) and waste disposal as well as the environmental management of these and other activities. The Engineering Geology for Society and Territory volumes of the IAEG XII Congress held in Torino from September 15-19, 2014, analyze the dynamic role of engineering geology in our changing world and build on the four main themes of the congress: Environment, processes, issues, and approaches. The congress topics and subject areas of the 8 IAEG XII Congress volumes are: 1. Climate Change and Engineering Geology 2. Landslide Processes 3. River Basins, Reservoir Sedimentation and Water Resources 4. Marine and Coastal Processes 5. Urban Geology, Sustainable Planning and Landscape Exploitation 6. Applied Geology for Major Engineering Projects 7. Education, Professional Ethics and Public Recognition of Engineering Geology 8. Preservation of Cultural Heritage.
