Download or read book Recommendations of the Committee for Waterfront Structures Harbours and Waterways written by HTG and published by John Wiley & Sons. This book was released on 2024-01-04 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recommendations have been completely restructured in this 12th (2020) edition of the EAU (10th English edition), the aim being to provide readers with a better, clearer arrangement of the chapters. In addition, the information published in the annual technical reports of the Waterfront Structures Committee since the publication of the 11th German edition have been incorporated in this new edition. The recommendations also take into account the new generation of standards consisting of Eurocode 7, the associated National Application Documents and supplementary national publications (DIN 1054:2010). In isolated instances, partial safety factors differing from those in the codes are specified on the basis of practical experience. Safety standards for ports, harbours and marine structures are therefore upheld. The recommendations satisfy the need for international acceptance in the planning, design, tendering, award of contract, construction, site supervision, acceptance and settlement of accounts for port, harbour and waterway facilities based on uniform approaches.

Book excerpt: In view of the demand for the research on the transport resistance characteristics and mechanical properties of CPB under the influence of temperature effect, the book comprehensively describes the studies on rheological and mechanical properties of CPB materials used in underground metal mines. This book covers a wide range of topics, including a new definition of CPB, past participation and flow-induced corrosion of pipeline under the constant temperature condition, multiphysics processes in CPB and the associated consolidation process, the variation of rheological parameters and transport resistance, prediction model for rheological properties, mechanical behavior and properties of CPB and fiber-reinforced CPB, and control technology to reduce the adverse effect of temperature. Therefore, an academic framework for the transport resistance characteristics and mechanical properties under the temperature effect was established in this book. Investigates rheological properties and multiphysics processes in CPB materials around the world Looks into systematic studies on pipe transport and mechanical properties of CPB under temperature effects Focuses mainly on the effect of temperature on paste transport and mechanical properties under the temperature effect, which provides a theoretical basis for safe and efficient filling operation and associated future research in this field Offer in-depth insights into the evolution of the rheological and mechanical properties of CPB under the effect of temperatures

Download or read book Underground Cable Thermal Backfill written by S.A. Boggs and published by Elsevier. This book was released on 2013-10-22 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underground Cable Thermal Backfill documents the proceedings of the ""Symposium on Underground Cable Thermal Backfill,"" held in Toronto, Canada, 17-18 September 1981. The symposium brought together research, design, and installation engineers from utilities, cable manufacturers, and universities to present and discuss developments in the field. The contributions of researchers at the symposium are organized into five chapters. Chapter 1 presents an overview of the state-of-the-art of cable backfill materials and soil thermal property measurements. The papers in Chapter 2 deal with developments in cable backfill materials. These include materials stabilized with moisture substitutes, pumpable materials, and materials stabilized with bound water. Chapter 3 covers thermal property measurements of soils and backfills. Through the automation of measurements and analysis using microprocessor based instruments and better control of experimental conditions, substantial improvements have been made in the area of measurement technology. Chapter 4 reports developments in the study of soil thermal stability and the implication thereof for thermal cable design. Chapter 5 discusses various aspects of thermal cable design, including methods for incorporating historical weather records to predict worst case soil and backfill thermal conductivities. This volume should serve as a useful introduction to the subject of cable thermal design for engineers involved in underground transmission and distribution systems.

This book was released on 2024-07-18 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a reference book for advanced graduate students and re-search engineers in rock mechanics related to mining engineering. The cemented tailings backfill (CTB) technique is widely used in deep underground mining, since this tech-nique is effective to support surrounding rock, control rockburst, reduce ground sub-sistence, and reduce surface disposal of tailings. Plenty of investigations have been attempted to experimentally or numerically evaluate the strength of CTB with different components (e.g., mixture of cement, tailings, fly ash, blast furnace slag, etc.) to ensure the geological stability when extracting adjacent stopes. After extracting ore from stopes, CTB is filled in the gob, stress redistribution occurs in the backfill stope and surrounding rocks. Due to the elasticity mismatch of these two kinds of material, differential de-formation occurs and they both resist the overburden pressure and deformation. As a result, the interactions between the surrounding rock and tailing backfill material have significant role in maintaining the long-term stability of mine stopes. Apart from the investigations on the static mechanical behaviors of rock- backfill composited backfill (RBCS) material, the RBCS in the stope are also exposed to disturbed stress (e.g., blast vibration, excavation, earthquake, etc.), and the disturbed stress is usually equivalent to cyclic or fatigue loads. As a result, investigations on rock-backfill interactions subjected to the disturbed stress are critical and significant to maintain the long- term stability of mine stopes.
