Download or read book valuation multi chelle de l tat des r seaux vieillissants de ponts routiers written by Abdoul Salam Bah and published by . This book was released on 2022 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les ouvrages vieillissent et leur état se détériore. Compte tenu de leur importance sociale et économique, ils constituent des vecteurs de transports construits dans le but d'assurer un service alliant un haut niveau de qualité, de sécurité et de fiabilité. Des budgets d'investissement, le plus souvent déficitaires, sont octroyés pour la construction d'infrastructures et d'ouvrages de génie civil. La fermeture des ouvrages pour les activités d'entretien ou de réparation, même temporaire, et, dans le cas de leur démolition, perturbe fortement la mobilité des usagers, en particulier, le mouvement des marchandises, social humain au niveau des activités de service et récréative, entraînant des répercussions économiques à différentes échelles et secteurs. La gestion des ouvrages permet l'auscultation des détériorations, la surveillance, et l'évaluation régulière d'un parc d'infrastructure en vue d'assurer un meilleur service aux utilisateurs. Nous aborderons pour cela, le contexte du projet, les besoins de recherche et ses objectifs. Par la suite, nous nous intéresserons plus en détail à la méthodologie qui décrit le modèle de gestion qui sera développé dans ce travail de recherche pour évaluer et gérer le parc d'ouvrages et les résultats attendus du projet de recherche. Une revue de la littérature est abordée afin d'identifier et analyser les modèles de gestions existants dans ce domaine de gestion des infrastructures.Le rapport s'articule autour de trois grandes parties : (1) Évaluation de la condition d'état d'un pont (2) Variation temporelle de la condition d'état d'un pont (3) Gestion intégrée du réseau routier. Ce rapport conclut sur les apports de la recherche et ouvre la perspective de développement à venir. Ce qui contribuera à maintenir et à en rétablir de façon optimale l'état des ouvrages ainsi qu'à stimuler l'économie.

Download or read book Arctic Shipping written by Frédéric Lasserre and published by Routledge. This book was released on 2019-09-05 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers both the present state of Arctic shipping and possible future trends with reference to the various sectors of maritime transportation: cruise tourism, container traffic and bulk shipping. Ports are analysed as tools that support the strategies of coastal states to foster the development of resource extraction, enhance the attractiveness of Arctic shipping lanes and enable the control of maritime activities through coast guard deployment. The aim of this book is to draw a picture of the trends of Arctic shipping. How is traffic evolving in Canada’s Arctic, or along the Northern Sea Route? Are there significant differences between bulk and container shipping segments when considering the Arctic market? How are the ports and the hinterland developing and what are the strategies behind those? How is the legal framework shaping the evolution of maritime transportation? The contributors to this book consider all of these questions, and more, as they map out the prospects for Arctic shipping and analyse in detail the development of Arctic shipping as a result of multi-variable interactions. This book will be key reading for industry professionals and post-graduate students alike.

Download or read book Good Governance and the European Union written by Deirdre Curtin and published by Intersentia nv. This book was released on 2005 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book approaches the notion of good governance from three different angles. First it establishes whether it is a meaningful notion at all by taking a closer look at the parameters of good governance. Secondly, the authors look at the institutional translation of the criteria of good governance. In a third dimension, the concept may be analysed in relation to a number of substantive issues.

Download or read book Modern Geotechnical Design Codes of Practice written by Patrick Arnold and published by IOS Press. This book was released on 2013 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ground is one of the most highly variable of engineering materials. It is therefore not surprising that geotechnical designs depend on local site conditions and local engineering experience. Engineering practices, relating to investigation and design methods site understanding and to safety levels acceptable to society, will therefore vary between different regions.The challenge in geotechnical engineering is to make use of worldwide geotechnical experience, established over many years, to aid in the development and harmonization of geotechnical design codes. Given the significant uncertainties involved, empiricism and engineering

Download or read book Reliability and Statistics in Geotechnical Engineering written by Gregory B. Baecher and published by John Wiley & Sons. This book was released on 2005-08-19 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk and reliability analysis is an area of growing importance in geotechnical engineering, where many variables have to be considered. Statistics, reliability modeling and engineering judgement are employed together to develop risk and decision analyses for civil engineering systems. The resulting engineering models are used to make probabilistic predictions, which are applied to geotechnical problems. Reliability & Statistics in Geotechnical Engineering comprehensively covers the subject of risk and reliability in both practical and research terms * Includes extensive use of case studies * Presents topics not covered elsewhere--spatial variability and stochastic properties of geological materials * No comparable texts available Practicing engineers will find this an essential resource as will graduates in geotechnical engineering programmes.

Download or read book Caterpillar Club Survivor written by Ross Smith Stagg and published by . This book was released on 2007 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spitfire pilot Ross Smith Stagg was one of 33 Allied airmen to defend Darwin against Japanese invasion on May 2, 1943. As one of 14 pilots shot down or experience mechanical failure in the ensuing battle, he parachuted into the sea 18 km from land, 100 km southwest of Darwin in the Fogg Bay area. He reached the shore in a dinghy. For the next 15 days he trudged through inhospitable country in a futile attempt to return to Strauss airbase. What should have been a few days walk turned into his worst possible nightmare as he stumbled aimlessly through mosquito and crocodile infested swamps. "It was almost six days I'd been without sleep, apart from a short period of unconsciousness and those few moments before I fell out of that tree," he said. " I became demented by the cavalcade of mosquitoes and hallucinating badly". His experience was only to worsen - he waded halfway across a tidal river to be confronted by a large saltie. Darwin historian John Haslett help Stagg map the original route by retracing his steps, even managing to relocate an American Kittyhawk Stagg found crashed in the middle of nowhere.
