Book Description
Rock Mechanics: Achievements and Ambitions contains the papers accepted for the 2nd ISRM International Young Scholars’ Symposium on Rock Mechanics, which was sponsored by the ISRM and held on 14–16 October 2011 in Beijing, China, immediately preceding the 12th ISRM Congress on Rock Mechanics. Highlighting the work of young teachers, researchers and practitioners, the present work provides an important stimulus for the next generation of rock engineers, because in the future there will be more emphasis on the use of the Earth’s resources and their sustainability, and more accountability of engineers’ decisions. In this context, it is entirely appropriate that the Symposium venue for the young scholars was in China — because of the rock mechanics related work that is anticipated in the future. For example, in the Chinese Academy of Sciences report, “Energy Science and Technology in China: A Roadmap to 2050”, it is predicted that China’s total energy demand will reach 31, 45, 61 and 66 x 108 tce (tonnes of coal equivalent) in 2010, 2020, 2035, 2050. The associated per capita energy consumption for the same years is estimated at 2.3, 3.1, 4.1 and 4.6 tce. This increasing demand will be met, inter alia, by the continued operation and development of new coal mines, hydroelectric plants and nuclear power stations with one or more underground nuclear waste repositories, all of which will be improved by more modern methods of rock engineering design developed by young scholars. In particular, enhanced methods of site investigation, rock characterisation, rock failure understanding, computer modelling, and rock excavation and support are needed. The topics in the book include contributions on: - Field investigation and observation - Rock constitutive relations and property testing - Numerical and physical modeling for rock engineering - Information technology, artificial intelligence and other advanced techniques - Underground and surface excavation and reinforcement techniques - Dynamic rock mechanics and blasting - Predication and prevention of geo-environmental hazard - Case studies of typical rock engineering Many of the 200 papers address these topics and demonstrate the skills of the young scholars, indicating that we can be confident in the continuing development of rock mechanics and rock engineering, leading to more efficient, safer and economical structures built on and in rock masses. Rock Mechanics: Achievements and Ambitions will appeal to professionals, engineers and academics in rock mechanics, rock engineering, tunnelling, mining, earthquake engineering, rock dynamics and geotechnical engineering.

Book Description
Las rocas son agregados naturales duros y compactos de partículas minerales con fuertes uniones cohesivas permanentes. La proporción de diferentes minerales, la estructura granular, la textura y el origen de la roca sirven para su clasificación geológica. Para proyectar y construir la cimentación, es necesario conocer las propiedades de los materiales que serán empleados, ya que las dimensiones de la cimentación están directamente relacionadas con las propiedades de los pétreos y el suelo. Es allí donde entra la mecánica de rocas, ciencia teórica y aplicada que estudia el comportamiento físico de las rocas sometidas a condiciones de esfuerzo de diversos orígenes. En términos generales, abarca el estudio de las obras subterráneas (como los túneles) y la construcción en superficie (como las canteras a cielo abierto o las cimentaciones de presas). El presente manual tiene como objetivo primordial informar a los ingenieros sobre los equipos y ensayos recomendados en la mecánica de rocas. Presenta los métodos de preparación y la realización de las pruebas utilizadas para determinar las propiedades físicas y mecánicas como son: densidad, porosidad, módulo de deformación, razón de Poisson, resistencia al corte, compresión y resistencia a la tracción indirecta, etc. Las magnitudes de los parámetros encontrados en el laboratorio serán usadas para el diseño ingenieril de obras civiles como la construcción de túneles, cimentaciones y estabilización de taludes carreteros, y en la ingeniería de minas o geología, donde la mecánica de rocas, además de ser parte importante para el diseño de pilares de minas subterráneas, ha sido considerada tradicionalmente como un asunto ligado a la seguridad.

Book Description
On October 14-19, 1990, the 6th International Conference on the Conservation of Earthen Architecture was held in Las Cruces, New Mexico. Sponsored by the GCI, the Museum of New Mexico State Monuments, ICCROM, CRATerre-EAG, and the National Park Service, under the aegis of US/ICOMOS, the event was organized to promote the exchange of ideas, techniques, and research findings on the conservation of earthen architecture. Presentations at the conference covered a diversity of subjects, including the historic traditions of earthen architecture, conservation and restoration, site preservation, studies in consolidation and seismic mitigation, and examinations of moisture problems, clay chemistry, and microstructures. In discussions that focused on the future, the application of modern technologies and materials to site conservation was urged, as was using scientific knowledge of existing structures in the creation of new, low-cost, earthen architecture housing.

Book Description
More often than not, it is difficult or even impossible to obtain directly the specific rock parameters of interest using in situ methods. The procedures for measuring most rock properties are also time consuming and expensive. Engineering Properties of Rocks, Second Edition, explores the use of typical values and/or empirical correlations of similar rocks to determine the specific parameters needed. The book is based on the author's extensive experience and offers a single source of information for the evaluation of rock properties. It systematically describes the classification and characterization of intact rock, rock discontinuities, and rock masses, and presents the various indirect methods for estimating the deformability, strength, and permeability of these components as well as the in situ rock stresses. - Presents a single source for the correlations on rock properties - Saves time and resources invested on in situ testing procedures - Fully updated with current literature - Expanded coverage of rock types and geographical locations
