Product Description
Tunnelling provides a robust solution to a variety of engineering challenges. It is a complex process, which requires a firm understanding of the ground conditions as well as structural issues. This book covers the whole range of areas which you need to know in order to embark upon a career in tunnelling. It also includes a number of case studies of real tunnel projects, to demonstrate how the theory applies in practice.
The coverage includes:
both hard rock and soft ground conditions
site investigation, parameter selection and design considerations
methods of improving the stability of the ground and lining techniques
descriptions of the various tunnelling techniques
health and safety considerations
monitoring of tunnels during construction.
Clear, concise and heavily illustrated, this is a vital text for final year undergraduate and MSc students and an invaluable starting point for young professionals.

n the last two decades most urban roads have experienced tremendous growth in traffic leading to frequent congestion and delays. Due to shrinking right-of-way and limited highway budgets, roadway planners and designers have been constantly exploring innovative ways of road design. Moreover, in recent years, highway agencies have often found it difficult to secure adequate funds for road construction due to conflicting public opinions and political views. This book addresses the intelligent concepts of the ancient endeavor of road design. An intelligent road design model that can quickly optimize horizontal and vertical alignments will allow quick evaluations of many competing alignment alternatives that should allow quicker political and public approval. For such purposes this book extensively discusses how a road alignment optimization model can be developed and applied in real case studies. Based on over eight years of research by the authors in intelligent road design and alignment optimization, this advanced text book will be appropriate for road planners, designers, senior undergraduate students and graduate students.

Modern seismology has faced new challenges in the study of earthquakes and their physical characteristics. This volume is dedicated to the use of new approaches and presents a state-of-the-art in historical seismology. Selected historical and recent earthquakes are chosen to document and constrain related seismic parameters using updated methodologies in the macroseismic analysis, field observations of damage distribution and tectonic effects, and modelling of seismic waveforms.

Guidelines for the evaluation of the response of occupants of fixed structures, especially buildings and off-shore structures, to low-frequency horizontal motion (0,063 to 1 Hz)
'Taking Shape' explores the evolution of scientific and academic theories that have resulted in the concept of sustainability. Susannah Hagan uses this as a basis to argue for developments in the future and argues that these theories are not 'just an intellectual and aesthetic regression' as they are often perceived to be. By focusing on the impact of the new theories of sustainable technology and new materials in architecture, Hagan moves the discourse and practice of environmental sustainability within architecture towards a greater degree of awareness of both its cultural significance and cultural potential. In short, it demonstrates the capacity of sustainable architecture to embrace cultural and technical innovation.
Enables you to understand the evolution of the theoretical arguments behind sustainability
Allows you to project into the future of sustainability technology rather than just examining the current situation
Provides you with a valuable insight into the relationship between the physical and cultural context and architecture

For architects, drawing is more than a convenient way to communicate ideas; it is an integral part of the creative process that has a profound impact on thinking and problem-solving. In Graphic Thinking for Architects and Designers, Third Edition, Paul Laseau demonstrates that more versatile and facile sketching leads to more flexible, creative approaches to design challenges. To encourage this flexibility and stimulate graphic thinking, he introduces numerous graphic techniques that can be applied in a variety of situations. He also helps readers acquire a solid grasp of basic freehand drawing, representational drawing construction, graphic note-taking, and diagramming.
Important features of this new edition include:
* Easy-to-understand discussions supported by freehand illustrations
* A new format with superior representation of techniques and concepts
* Dozens of new and updated illustrations
* Extensive coverage of new technologies related to the graphic thinking process
For architects and students who want to maximize their creativity, Graphic Thinking for Architects and Designers is a valuable tool in the pursuit of architectural solutions to contemporary design problems.

The construction of buildings and structures relies on having a thorough understanding of building materials. Without this knowledge it would not be possible to build safe, efficient and long-lasting buildings, structures and dwellings. Building materials in civil engineering provides an overview of the complete range of building materials available to civil engineers and all those involved in the building and construction industries.
The book begins with an introductory chapter describing the basic properties of building materials. Further chapters cover the basic properties of building materials, air hardening cement materials, cement, concrete, building mortar, wall and roof materials, construction steel, wood, waterproof materials, building plastics, heat-insulating materials, sound-absorbing materials and finishing materials. Each chapter includes a series of questions, allowing readers to test the knowledge they have gained. A detailed appendix gives information on the testing of building materials.
