Overview of current South-African vertical circular Shaft Construction Practice
Author: A. B. Douglas - R. B. Pfutzenreuter | Size: 6 MB | Format:PDF | Quality:Scanner | Publisher: Association of South African Mine Managers and Cementation Mining | Year: 1990 | pages: 41 | ISBN: n.a.
This paper deals with trends in the South African underground mining industry and its demand for shafts.
The development of the modem subsidiary sinking industry and the depths and dimensions of shafts which are being predominantly constructed.
A description of all the phases and activities involved in the construction of a typical shaft follows.
Commencing with the construction of the collar and pre-sinking, the establishment of plant, equipment and gearing up of a project to the commencement of fast sinking operations.
The paper then deals with sinking routines, ie. lashing, blow over, drilling and blasting are detailed and comment is made on modem developments in mechanised drilling and watergel based explosives.
Note from uploader:
I've been working in recent years according to this same set of rules/recommendations under the so-called Mine Health & safety Act and, although constraining especially at the beginning of the any works, I found this way of doing productive and highly safe.

Author: L. G. Jaeger - B. Bakht | Size: 56 MB | Format:PDF | Quality:Scanner | Publisher: McGraw Hill | Year: 1989 | pages: 331 | ISBN: 007032333X
Methods of transverse load distribution analysis of highway bridges range in sophistication from the overly simplified American Association of State Highway and Transportation Officials (AASHTO) methods to highly complex finite element methods. The former, because of being too simple, are excessively conservative, and the latter, which require fairly complex standard programs, are prone to common errors of idealization and interpretation of results as well as being relatively costly. This book is a companion volume to Bridge Analysis Simplified (McGraw-Hill, 1985). The earlier book expands upon the simple AASHTO approach to provide a number of more accurate manual methods of analysis for application in conjunction with North American and similar codes. Our objective in writing this second work is to provide to bridge designers alternative methods of bridge analysis which are refined, which can be implemented through even the most basic microcomputer, and which do not have the limitations of the simplified methods.

Author: B. Bakht - L. G. Jaeger | Size: 27 MB | Format:PDF | Quality:Scanner | Publisher: McGraw Hill | Year: 1985 | pages: 294 | ISBN: 00070030200
Most highway bridges in North America are designed by the American Association of State Highway and Transportation Officials (AASHTO) specifications. A principal assumption underlying the analysis methods of AASHTO is that bridges of a given type (e.g., slab-on-steel girder bridges) all behave similarly in their live-load distribution properties. By contrast with the North American tradition, bridge analysis in Europe tends to be highly analytical and, usually, computer-based. Such methods as the grillage analogy method, the orthotropic plate method, and the finite element and finite strip methods are extensively used. This book presents a number of simple methods of analysis which expand upon the AASHTO approach, making it consistent with the more refined European methods. The simple methods presented in this book are derived from the results of computer-based rigorous analyses. The book is intended to be useful both to the practicing bridge engineer and to the engineering student. It thus contains both "know-how" and "know-why" material. For the most part the know-why material is to be found in Chapter 1, while the remaining chapters constitute a know how treatment which is virtually complete in itself. The book is also intended to bring home to the reader the physical behavior of bridges of different types and to help the designer in establishing a "feel'' for the mechanisms of load distributions.

Author: A. R. Cusens - R. P. Pama | Size: 22 MB | Format:PDF | Quality:Scanner | Publisher: John Wiley & Sons | Year: 1975 | pages: 279 | ISBN: 0471189987
The construction of bridges comprises one section of the work of the civil engineer which has an immediate 1mpact upon the public.
The reasons for this impact are not hard to find since most major bridges combine a strong visual impression together with obvious benefits in the way of improved communications.
The action of bridging hitherto impassable barriers also inspires a deep and dramatic sense of achievement.
Bridge-building has occupied much of the working lives of the great civil engineers in the last century and a half.
In the light of recent publicity over the failure of bridges during construction it is almost unnecessary to emphasize that professional skill and ingenuity of the highest order are involved.
In a recent paper Dr. Kerensky aptly expressed the feelings of a bridge engineer with the words: 'Design and construction of bridges is a lifelong calling-exacting and rewarding'.
It is evident from its title that this book is concerned primarily with limited aspects of bridge design.
These will be defined later in this first chapter but, initially, in order to provide a general introduction to the subject, current trends in bridge design and construction will be outlined.
