This paper presents an experimental investigation on contact behaviors of idealized granules which are bonded together with cement. First, by using the specimen preparation devices, two aluminum alloy rods with the same size are glued together by cement with the cement water ratio 0.34.

Slopes as inclined earth surfaces occur everywhere. They are more or less worked by man and thus the condition is changed. Thus, the effects of these changes should also be considered and a certainty about the safety of the slopes should be obtained. Only with
this knowledge should changes be carried out in order to be able to estimate their effect on people and the environment.

This book is a peer-reviewed and edited volume that contains keynote lectures and extended abstracts of papers that were received for EUROCK 2014 – The 2014 ISRM European Symposium, which will be held in the city of Vigo SPAIN on 27–29 May, 2014.

Настоящий стандарт распространяется на твердые горные породы с пределом прочности при одноосном сжатии не менее 1 МПа и устанавливает метод определения предела их прочности при объемном сжатии цилиндрических или призматических образцов. <...>

Настоящий стандарт распространяется на твердые горные породы с пределом прочности при одноосном сжатии не менее 5 МПа и устанавливает метод определения предела их прочности при срезе со сжатием цилиндрических или призматических образцов.

Настоящий стандарт распространяется на твердые (скальные и полускальные) горные породы м устанавливает методы определения предела их прочности при одноосном сжатии:
одноосное сжатие образцов правильной формы плоскими плитами (породы с пределом прочности при одноосном сжатии не менее S МПа):
разрушение образцов-плиток плоскими соосными пуансонами (породы с пределом прочности при одноосном сжатии от 10 до ISO МПа). <...>

The fi rst three parts of the section address the development of soil mechanics and geotechnical engineering as a distinct discipline over the past 80 years or so. Chapter 2 Foundations and other geotechnical elements in context - their role explains the importance of foundations and structures built in or of the ground within civil engineering and construction, and the need for a formal and holistic geotechnical engineering design process. Chapter 3 A brief history of the development of geotechnical engineering gives a history of the development of geotechnical engineering at the borderline between science and art, with the latter defi ned by Terzaghi in 1957 as a ‘mental processes leading to satisfactory results without the assistance of step-for-step logical reasoning’. This is refl ected in the ‘geotechnical triangle’, described in Chapter 4 The geotechnical triangle, which emphasises the essential elements of successful geotechnical engineering as understanding the ground, material properties and relevant precedence (well-winnowed experience), connected by an appropriate model for analysis. <...>
