Ground Anchorages and Anchored Structures


Book Description

This volume presents the proceedings of the first major international conference for over twenty years on the state-of-the-art of ground anchorage technology. Practical issues relating to construction and installation of anchorages are considered in a series of examples of engineering projects from around the world.




Corrosion and Corrosion Protection of Prestressed Ground Anchorages


Book Description

This state of the art report summarizes the mechanisms and types of corrosion to which a ground anchorage based on a prestressing tendon can be subjected. The chemical, electrochemical and bacterial reactions between agressive soils and steel and concrete are dealt with in detail. There is a carefully recorded and analysed list of a number of known cases of tendon corrosion. A corrosion protection philosophy is proposed, with five classes of protection, with examples of such protection in current practice.










Fourth International Conference on Current and Future Trends in Bridge Design, Construction and Maintenance


Book Description

This is a state-of-the-art reference, an exchange of innovative experience, creative thinking and industry forecasts. This volume presents the proceedings of the fourth international conference in this series based in the Asia Pacific region, in Kuala Lumpur in October 2005 and is applicable to all sectors of the bridge engineering community. BACKGROUND KNOWLEDGE AND FUTURE PERFORMANCE The Institution of Civil Engineers has collaborated with internationally renowned bridge engineers to organise three successful conferences to celebrate the enormous achievements made in the field of bridge engineering in recent years. As a discipline, bridge engineering not only requires knowledge and experience of bridge design and construction techniques but must also deal with increasing challenges posed by the need to maintain the long-term performance of structures throughout an extended service life. In many parts of the world natural phenomena such as seismic events can cause significant damage to force major repairs or reconstruction. Therefore, it is appropriate that the first plenary session of this conference is entitled Engineering for Seismic Performance. READERSHIP This compilation of papers will benefit practising civil and structural engineers in consulting firms and government agencies, bridge contractors, research institutes, universities and colleges. In short, it is of importance to all engineers involved in any aspect of the design, construction and repair, maintenance and refurbishment of bridges.




Design and Construction of Soil Anchor Plates


Book Description

Primarily designed and constructed to resist outwardly directed loads imposed on the foundation of a structure, anchor plates play an important role in the design of structures (including seawalls, transmission towers, tunnels, buried pipelines, and retaining walls). Design and Construction of Soil Anchor Plates focuses on the various theories based on the design and construction techniques of anchor plates in soil mechanics. The focus of this reference is on design methods, theories, and procedures for constructing permanent or temporary ground anchors and anchored systems. Topics include: General Requirements of Vertical Anchor Plates and Design Criteria, Estimation of Ultimate Capacity in Vertical Anchor Plates, General Requirements of Vertical Anchor Plates and Design Criteria, Type and Length of Inclined Anchor Plates, Early Theories on Anchor Plates in Multi-Layers Soil, and Basic Theories on Passive Pressure in Vertical Anchor Plates. With this reference, researchers and designers will find a valuable guide to the various theories, techniques, and equations for anchor design. Basic theories on passive pressure in vertical anchor plates Estimation of ultimate capacity in vertical anchor plates Uplift capacity for shallow anchor plates Requirements of vertical anchor plates and design criteria Type and length of inclined anchor plates




Ground Anchors and Anchored Systems


Book Description

This book presents state-of-the-practice information on the design and installation of cement-grouted ground anchors and anchored systems for highway applications. The anchored systems discussed include flexible anchored walls, slopes supported using ground anchors, landslide stabilization systems, and structures that incorporate tiedown anchors. This book draws extensively in describing issues such as subsurface investigation and laboratory testing, basic anchoring principles, ground anchor load testing, and inspection of construction materials and methods used for anchored systems. This book provides detailed information on design analyses for ground anchored systems. Topics discussed include selection of design earth pressures, ground anchor design, design of corrosion protection system for ground anchors, design of wall components to resist lateral and vertical loads, evaluation of overall anchored system stability, and seismic design of anchored systems. Also included in this book are two detailed design examples and technical specifications for ground anchors and for anchored walls.
