Three large rock-bolted underground cavities were constructed at the Nevada Test Site. Two of the cavities, approximately 100 feet in diameter and 140 feet high, were constructed at a depth of 1300 feet in a very weak tuff of excellent rock mass quality. The third cavity, approximately 60 feet in diameter and 80 feet high, was constructed at a depth of 350 feet in a jointed granite of high intact strength and fair to good rock mass quality. The stability of the cavities was monitored throughout construction by measuring rock displacements, observing fractures in near-surface rock, and observing the behavior of the rock-bolt support system. Supporting field and laboratory tests were performed in order to evaluate intact and in-situ properties of the rock mass. Radial movement of the cavities was measured using extensometers anchored at various depths in holes drilled from the cavity surface. Displacement versus depth profiles were used to determine the depth at which rock movement was concentrated. By comparing rock movement with excavation and support progress, a continual estimate of the cavity stability was obtained. Large displacements, or large rates of displacement, were indicative of potentially unstable behavior. Displacements were compared with displacements predicted from elastic theory, using a finite element solution and simple closed solutions. (Author).
KWIC Index of Rock Mechanics Literature, Part 2: 1969-1976 is an index of subjects in rock mechanics. The KWIC (keyword-in-context) index is produced by cyclic permutation of significant words in the title of the publication. The text covers materials in rock mechanics and geomechanics published around the 70s. The book will be of great use to students, researchers, and practitioners of geological sciences.
This second edition of the successful Foundations on Rock presents an up-to-date practical reference book describing current engineering practice in the investigation, design and construction of foundations on rock. An extra chapter on Tension Foundations has been included. The methods set out are readily applicable to high rise buildings, bridges,
Analysis, Modeling & Design is the third volume of the five-volume set Rock Mechanics and Engineering and contains twenty-eight chapters from key experts in the following fields: - Numerical Modeling Methods; - Back Analysis; - Risk Analysis; - Design and Stability Analysis: Overviews; - Design and Stability Analysis: Coupling Process Analysis; - Design and Stability Analysis: Blast Analysis and Design; - Rock Slope Stability Analysis and Design; - Analysis and Design of Tunnels, Caverns and Stopes. The five-volume set “Comprehensive Rock Engineering”, which was published in 1993, has had an important influence on the development of rock mechanics and rock engineering. Significant and extensive advances and achievements in these fields over the last 20 years now justify the publishing of a comparable, new compilation. Rock Mechanics and Engineering represents a highly prestigious, multi-volume work edited by Professor Xia-Ting Feng, with the editorial advice of Professor John A. Hudson. This new compilation offers an extremely wideranging and comprehensive overview of the state-of-the-art in rock mechanics and rock engineering and is composed of peer-reviewed, dedicated contributions by all the key experts worldwide. Key features of this set are that it provides a systematic, global summary of new developments in rock mechanics and rock engineering practices as well as looking ahead to future developments in the fields. Contributors are worldrenowned experts in the fields of rock mechanics and rock engineering, though younger, talented researchers have also been included. The individual volumes cover an extremely wide array of topics grouped under five overarching themes: Principles (Vol. 1), Laboratory and Field Testing (Vol. 2), Analysis, Modelling and Design (Vol. 3), Excavation, Support and Monitoring (Vol. 4) and Surface and Underground Projects (Vol. 5). This multi-volume work sets a new standard for rock mechanics and engineering compendia and will be the go-to resource for all engineering professionals and academics involved in rock mechanics and engineering for years to come.
