دانلود کتاب International Conference on Ground Anchorages and Anchored Structures in Service : proceedings of the two day international conference organised by the Institution of Civil Engineers and held in London on 26th and 27th November 2007

Millions of ground anchorages have been installed over the past 80 years with relatively few recorded failures. However, as permanent anchorages in service become older, the subject is of growing importance; particularly for anchorages installed over 30 years ago: many of which were designed with corrosion protection considered inadequate by today's standards. This book shows how routine inspection and monitoring can extend the service life of the anchored structures that represent key elements of a country's infrastructure. Where inspection highlights unacceptable tendon corrosion or over-stressing, the results provide early warning of the need for precautionary or remedial measures, in order to safeguard the integrity of the anchored structure. The findings in this book show that in spite of these benefits, sufficient attention is not currently paid to routine maintenance inspection and service behaviour monitoring
