Download or read book Manual para el desarrollo de ferrocarriles urbanos written by Daniel Pulido and published by World Bank Publications. This book was released on 2020-11-09 with total page 814 pages. Available in PDF, EPUB and Kindle. Book excerpt: A nivel global, ciudades buscan desarrollar soluciones de transporte asequibles, ecológicas y socialmente responsables que puedan satisfacer las necesidades de conectividad de las crecientes poblaciones metropolitanas y respaldar el futuro desarrollo económico y urbano. Cuando los sistemas ferroviarios urbanos se planifican e implementan adecuadamente como parte de una red de transporte público más amplia, éstis pueden brindar vías rápidas de movilidad y acceso vital a los centros urbanos desde la periferias. Los servicios ferroviarios urbanos de alto rendimiento, cuando se abordan cuidadosamente en el contexto de un proyecto de desarrollo, pueden ayudar a mejorar la calidad de vida de los ciudadanos brindándoles acceso a oportunidades laborales y servicios esenciales, tanto del entorno urbano inmediato como de comunidades vecinas. Este manual sintetiza y difunde conocimientos sobre planificación, implementación y operación de los proyectos ferroviarios urbanos para: i) destacar la necesidad de realizar estudios tempranos y planificar los proyectos, ii) contribuir a que los proyectos sean más sostenibles (desde el punto de vista económico, social y ambiental); iii) mejorar los beneficios socioeconómicos de los usuarios y el acceso de estos a distintas oportunidades; iv) maximizar el valor de la participación privada, cuando corresponda, y v) fortalecer la capacidad de las instituciones encargadas de la gestión e implementación de los proyectos. Se ofrece experiencia para lidiar con los desafíos técnicos, institucionales y financieros a los que se enfrentan los tomadores de decisiones de proyectos ferroviarios urbanos. Se reúnen los conocimientos especializados del personal del Banco Mundial y el aporte de numerosos especialistas para sintetizar buenas prácticas y recomendaciones basadas en experiencia global que no responden a intereses comerciales, financieros ni políticos, entre otros. El material presentado tiene como objetivo servir de guía imparcial para maximizar el impacto y afrontar los desafíos que conllevan los sistemas ferroviarios urbanos en las ciudades de países desarrollados y en desarrollo. No se brinda un enfoque único, sino que se reconocen las complejidades y los distintos contextos existentes cuando se aborda un proyecto de desarrollo ferroviario urbano; de ese modo, se apoya a las autoridades a prepararse para formular las preguntas adecuadas, analizar las cuestiones clave, llevar a cabo los estudios necesarios, aplicar las herramientas apropiadas y aprender de las buenas prácticas internacionales, todo ello en el oportuno momento del proceso de desarrollo del proyecto.
Download or read book Concrete Permeability and Durability Performance written by Roberto J. Torrent and published by CRC Press. This book was released on 2021-12-22 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Durability and service life design of concrete constructions have considerable socio-economic and environmental consequences, in which the permeability of concrete to aggressive intruders plays a vital role. Concrete Permeability and Durability Performance provides deep insight into the permeability of concrete, moving from theory to practice, and presents over 20 real cases, such as Tokyo’s Museum of Western Art, Port of Miami Tunnel and Hong Kong-Zhuhai-Macao sea-link, including field tests in the Antarctic and Atacama Desert. It stresses the importance of site testing for a realistic durability assessment and details the "Torrent Method" for non-destructive measurement of air-permeability. It also delivers answers for some vexing questions: Should the coefficient of permeability be expressed in m2 or m/s? How to get a "mean" pore radius of concrete from gas-permeability tests? Why should permeability preferably be measured on site? How can service life of reinforced concrete structures be predicted by site testing of gas-permeability and cover thickness? Practitioners will find stimulating examples on how to predict the coming service life of new structures and the remaining life of existing structures, based on site testing of air-permeability and cover thickness. Researchers will value theoretical principles, testing methods, as well as how test results reflect the influence of concrete mix composition and processing.

Download or read book Geotechnical Engineering in the XXI Century Lessons learned and future challenges written by N.P. López-Acosta and published by IOS Press. This book was released on 2019-11-26 with total page 3006 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first Pan-American Conference on Soil Mechanics and Geotechnical Engineering (PCSMGE) was held in Mexico in 1959. Every 4 years since then, PCSMGE has brought together the geotechnical engineering community from all over the world to discuss the problems, solutions and future challenges facing this engineering sector. Sixty years after the first conference, the 2019 edition returns to Mexico. This book, Geotechnical Engineering in the XXI Century: Lessons learned and future challenges, presents the proceedings of the XVI Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XVI PCSMGE), held in Cancun, Mexico, from 17 – 20 November 2019. Of the 393 full papers submitted, 335 were accepted for publication after peer review. They are included here organized into 19 technical sessions, and cover a wide range of themes related to geotechnical engineering in the 21st century. Topics covered include: laboratory and in-situ testing; analytical and physical modeling in geotechnics; numerical modeling in geotechnics; unsaturated soils; soft soils; foundations and retaining structures; excavations and tunnels; offshore geotechnics; transportation in geotechnics; natural hazards; embankments and tailings dams; soils dynamics and earthquake engineering; ground improvement; sustainability and geo-environment; preservation of historic sites; forensics engineering; rock mechanics; education; and energy geotechnics. Providing a state-of-the-art overview of research into innovative and challenging applications in the field, the book will be of interest to all those working in soil mechanics and geotechnical engineering. In this proceedings, 58% of the contributions are in English, and 42% of the contributions are in Spanish or Portuguese.
