PRACTICAL APPLICATIONS OF GROUND IMPROVEMENT

Ground Improvement techniques are often used to improve sub soil properties in terms of their bearing capacity, shear strength, settlement characteristics, drainage, etc. These techniques have a wide range of applicability from coarse grained soils to fine grained soils. Depending upon the loading conditions and nature of soil, a suitable technique which is also economical needs to be adopted. This paper gives the concept and theory of a few ground improvement techniques and describes the practical application of these techniques along with a case history for each of the techniques.

Approved Code of Practice for Demolition

This code of practice has been prepared to inform employers and employees of precautions and safe practices that should be followed when carrying out demolition work. It is hoped that the safe practices recommended will be a useful aid to those involved in demolition, to avoid the potential hazards associated with the work.

Additional information about demolition can be found in British Standard BS 6187:1982 Code of practice for demolition or in Australian Standard 2601:1983 SAA Demolition code, or in other references listed in Appendix C.

Legislation controlling demolition work includes the Building Act 1991, the Health and Safety in Employment Act 1992, the Resource Management Act 1991 and the Historic Places Act 1980.

FUNDAMENTALS OF GAS DYNAMICS

This book is written for the average student who wants to learn the fundamentals of gas dynamics. It aims at the undergraduate level and thus requires a minimum of prerequisites. The writing style is informal and incorporates ideas in educational technology such as behavioral objectives, meaningful summaries, and check tests. Such features make this book well suited for self-study as well as for conventional course presentation. Sufficient material is included for a typical one-quarter or onesemester course, depending on the student’s background.

Our approach in this book is to develop all basic relations on a rigorous basis with equations that are valid for the most general case of the unsteady, three-dimensional flow of an arbitrary fluid. These relations are then simplified to represent meaningful engineering problems for one- and two-dimensional steady flows. All basic internal and external flows are covered with practical applications which are interwoven throughout the text. Attention is focused on the assumptions made at every step of the analysis; emphasis is placed on the usefulness of the T –s diagram and the significance of any relevant loss terms.

Examples and problems are provided in both the English Engineering and SI systems of units. Homework problems range from the routine to the complex, with all charts and tables necessary for their solution included in the Appendixes. The goals for the user should be not only to master the fundamental concepts but also to develop good problem-solving skills. After completing this book the student should be capable of pursuing the many references that are available on more advanced topics.

Professor Oscar Biblarz joins Robert D. Zucker as coauthor in this edition. We have both taught gas dynamics from this book for many years. We both shared in the preparation of the new manuscript and in the proofreading. This edition has been expanded to include (1) material on conical shocks, (2) several sections showing how computer calculations can be helpful, and (3) an entire chapter on real gases, including simple methods to handle these problems. These topics have made the book more complete while retaining its original purpose and style.
