Abstract Increased roadway traffic demands have led to a notable increase of large diameter tunnel boring machine-driven tunnels across the world. The technological advancements of tunnel boring machines have made them a viable technical option for tunneling in difficult conditions in urban environments at ever increasing diameters. Such tunnels utilize precast concrete segmental linings. Although precast concrete segments have been widely used and designed in the US since the mid-1970s, the significant increase in diameter demands brings about new challenges in design and construction. Various international publications and practice manuals have been authored about segmental lining design. The present document is the first phase of an FHWA research initiative focused on the design of large diameter precast concrete segmental linings. This document provides an overview of the literature survey and synthesizes the current state of the practice along with raising potential knowledge gaps for future research. 17. Key Words 18.

The basic technology of conventionally reinforced precast concrete segments is relatively matured for smaller diameter tunnels. It has been in use in the United States for nearly 40 years (and even longer in other parts of the world). However, recent advances in the use of steel fibers for concrete reinforcement, joint hardware and details, gasket technology, high-strength concrete mixes, and material durability warrant study to provide uniformity of application, identification of practices and details for use in large-diameter tunnels. The work of this research includes a literature survey to identify gaps in the current body of knowledge (“knowledge gaps”), computer modeling and laboratory research, and engagement of industry stakeholders through a workshop that will be used to solicit input on the research plans. The work herein will also build on prior research work performed on design approaches for Tunnel Boring Machine (TBM) excavated tunnels. The objective of this research is to provide technical expertise to advance the current state of practice for the analysis, design, detailing, fabrication, installation, inspection, and maintenance of precast concrete segmental tunnel linings for large diameter highway TBM-tunnels in the US. The research includes several elements: • conducting a literature survey and development of a literature synthesis of the current state of the practice; • development of computer modeling and laboratory testing workplans; • hosting an industry workshop to solicit input from technical organizations, designers, contractors and researchers regarding the workplans; • executing research workplans and presenting research results in reports that summarize the finding of the research; • development of document presenting suggested practices for design of large diameter precast concrete segmental tunnel linings. This document provides an overview of the conducted literature survey and synthesizes the current state of the practice. Thus, it may potentially lead to additional research. ii Precast Concrete Segmental Liners Large Diameter Road Tunnels – Literature Survey and Synthesis Notice This document is disseminated under the sponsorship of the U.S. Department of Transportation (USDOT) in the interest of information exchange.

If it is not properly addressed, fire in a tunnel can result in loss of life to both tunnel users and the fire and rescue services. The result- ing economic losses for both the tunnel owner/operator and to the local economy and environ- ment can be catastrophic. This document is the result of a co-operative effort between the World Road Association (PIARC) Technical Committee on Road tunnel Operation (C 3.3) and its Working Group 6 Fire and Smoke Control, and the International Tunnelling Association (ITA) Working Group 6 Re- pair and Maintenance of Underground Structures. The purpose of this co-operative effort is to develop guidelines for resistance to fire for road tunnel structures.

  • 5. Noise Pollution
    5. Noise pollution 1. Please describe the present situation and development over the last five to ten years in relation to (max. 1,000 words): Within the scope of implementing “Directive 2002/49/EC of the European Parliament and the Council of 25 June 2002, relating to the assessment and management of environmental noise”, the proportion of Hamburg’s population subjected to noise emanations from road, railway and air traffic sources as well as industrial, commercial and port facilities has been determined in terms of the noise indicators L den, for noise levels during the day, evening and night, and L night, for noise levels at night. The assessment was calculated on the basis of national provisional computation methods; namely, the “Provisional computation method for environmental noise on roads – VBUS”, the “Provisional computation method for environmental noise on railways – VBUSch”, the “Provisional computation method for environmental noise at airports – VBUF”, the “Provisional computation method for environmental noise from industry and commercial facilities – VBUI”, and the “Provisional computation method for determining the number of individuals exposed to environmental noise – VBEB”. In terms of the industrial, commercial and port sector, in addition to plants located in the port area, only those industrial or commercial zones with one or more plants as per Appendix 1 of the “European Council Directive 96/61/EC of 24 September 1996 concerning integrated pollution prevention and control” are afforded consideration. The period of reference is 2006. Accordingly, the number of individuals affected is as follows: Affected by L den > Affected by L night > 55 dB(A) 45 dB(A) Road traffic 363600 420900 Rail traffic 56200 38900 (L night > 50 dB(A)) Air traffic 43700 5000 (L night > 50 dB(A)) Industry/commercial 4200 10200 /port facilities In line with the requirements of the EU directive, the analyses are updated at least every 5 years, from which commensurate developments regarding issues of concern can be ascertained.

  • Policy Brief
    Policy Brief Moving Toward More Accessible and Productive Transportation in the Puget Sound By Wendell Cox, Principal, Demographia (Wendell Cox Consultancy) October 2019 Key Findings 1. The overwhelming share of population and employment in the Puget Sound is outside the city of Seattle. Even with the city of Seattle’s unprecedented population and employment growth since 2010, a sizable majority of new residents and employment have located outside the city. 2. The Puget Sound region is dispersed, both in employment and residences. While downtown Seattle is the strongest Puget Sound Regional Council (PSRC) employment center and has experienced astounding growth since 2010, more than 85 percent of employment is outside downtown. 3. The “Amazon Boom” has brought unprecedented employment growth to downtown Seattle and seems unlikely to play as strong a role in the future. However, even with the “Amazon Boom,” nearly 60 percent of employment growth has been outside the city of Seattle since 2010. 4. Autos are used by more than two-thirds of commuters to work trip locations throughout the Puget Sound, with a three-quarters share outside the city of Seattle and just shy of a 50 percent share in the city of Seattle. 5. Transit serves a principally niche market, with 48 percent of the commuting to downtown Seattle, and a 9.3 percent share to the rest of the city. Only 3.5 percent of work trips to destinations in the rest of the Puget Sound are on transit. 6. Downtown dominates transit commuting. PSRC employment centers outside the city of Seattle exhibit transit commuting characteristics more reflective of suburban areas outside centers, with virtually no realistic potential for reducing vehicle miles through expanding transportation choices.
