    MARMARAY PROJECT - TURKEY Istanbul is a city where historical and cultural values must be preserved and at the same time modern railway facilities have to be installed to decrease the environmental impact of public transportation and increase the capacity, reliability and comfort of the railway systems. The Project provides an upgrading of the commuter rail system in Istanbul, connecting Halkalı on the European side to the Asian side with an uninterrupted, modern, high-capacity commuter rail system. Railway tracks in both sides of Istanbul Strait will be connected to each other through a railway tunnel connection under the Istanbul Strait. The line goes underground at Yedikule, continues through the Yenikapı and Sirkeci new underground stations, passes under the Istanbul Strait, connects to the Üsküdar new underground station and emerges at Sögütlüçesme. The entire upgraded and new railway system will be approximately 76 km long. The main structures and systems; include the immersed tube tunnel, bored tunnels, cut-and-cover tunnels, at - grade structures, three new underground stations, 37 surface stations (renovation and upgrading), operations control centre, yards, workshops, maintenance facilities, upgrading of existing tracks including a new third track on ground, completely new electrical and mechanical systems and procurement of modern railway vehicles. The idea of a railway tunnel under the Istanbul Strait was first raised in 1860. However, where the tunnel under the Istanbul Strait crosses the deepest parts of the Strait, the old-fashioned techniques would not allow the tunnel to be on or under the seabed, and therefore the design indicated a "floating" type of tunnel placed on pillars constructed on the seabed.

The Parallel Thimble Shoal Tunnel project will involve the construction of a two-lane bored tunnel from the CBBT’s southernmost island (#1 Island) under Thimble Shoal Channel to #2 Island. This will be the FIRST bored roadway tunnel in the Hampton Roads region as well as the Commonwealth. Not only did this bored tunnel solution offer a less expensive Parallel Existing Thimble Thimble Shoal Shoal Tunnel price tag, but it will have less environmental impact than the traditional immersed tube tunnel construction and will have less impact on the ship traffic that sails Thimble Shoal Channel. Tunnel When complete, this tunnel, which runs parallel to the existing tunnel, will carry southbound traffic headed towards Virginia’s mainland.

  • The Effect of Wave Passage on Immersed Tube Tunnels - Busan Geoje Fixed Link in South Korea
    IABSE SYMPOSIUM WEIMAR 2007 The effect of wave passage on immersed tube tunnels - Busan Geoje Fixed Link in South Korea Ronald HEIJMANS Peter JACKSON Dr. Thomas KASPER Civil Engineer Geotechnical Engineer Civil Engineer ARCADIS Infra, Cowi Cowi Amersfoort, The Netherlands Copenhagen, Denmark Copenhagen, Denmark [email protected] [email protected] [email protected] Guido MEINHARDT Jean SCHMITT Dr. Hessel VOORTMAN Geotechnical Engineer Project Engineer-in-charge Hydraulic Engineer ARCADIS Infra Ingerop ARCADIS Infra, Amersfoort, The Netherlands Paris, France Amersfoort, The Netherlands [email protected] [email protected] [email protected] Summary A special feature of the Busan-Geoje Fixed Link in South Korea is the foundation of an immersed tube tunnel in a trench of soft marine clay. The tunnel is subject to wave loads due to 9.2 meter high hurricane waves which jeopardize the stability of the tunnel. Analytical analyses, scale model tests and numerical analyses have been made to investigate this problem. This paper gives an overview of the analyses, performed from schematization of the non-linear waves to pressure variations at seabed, modelling of the wave induced groundwater flow and its effects on the tunnel buried in the seabed. This is followed by a discussion of the results and consequences for the design of the tunnel. Keywords: immersed tube tunnel; wave effect; numerical modelling, non-linear waves 1. Introduction 1.1 Introduction of the project The Busan Geoje Fixed Link consists of an 8.2 km long motorway with two large cable stayed bridges and a 3.3 km long immersed tube tunnel as main structures.

    Dynamic analysis of an immersed tunnel in Izmir Análisis dinámico de un túnel sumergido en Izmir Isfendiyar Egeli (Main Author) Usak University, Civil Engineering Department Bir Eylul Campus, 64000, Usak (Turkey) İ[email protected] Cagdas Gurbuz (Corresponding Author) Graduate Research Student, Izmir Institute of Technology Urla Campus, 35430, Izmir (Turkey) [email protected] Manuscript Code: 885 Date of Acceptance/Reception: 17.04.2018/27.01.2017 DOI: 10.7764/RDLC.17.1.103 Abstract The original design of the planned Izmir Bay Immersed Tube Tunnel, considered it to be a continuous subsea tunnel for the whole length of about 7.6 km. But this was later changed into having 2 shorter tubes of 2.7 km long each connected thru’ a 2.2 km long artificial island created in the middle of the bay from the excess dredged material, a concept which also reduces costs and increases efficiency. This island will serve as a venue for the 2025 Expo Exhibition, which Izmir city will apply to organize in the future. Reason for the research study was to provide a preliminary design, using a dynamic analysis, during the current pre-feasibility stage, of the immersed tunnel to show whether it can be built across the Izmir Bay. This paper takes into account the new alignment and presents the results of a 2-D dynamic analysis conducted of the prefabricated 100m long tunnel elements, sitting within a backfilled dredged ditch, dug after the recommended ground improvement was carried out. Analyses considered staged construction and the results showed that: Tunnel units and its surrounding soils inside the dredged ditch act together to provide a better earthquake response with a damping effect of the earthquake force; Tunnel units do not float to the sea surface, but continued to stay inside the dredged ditch and applied positive stresses to the foundations during the design earthquakes.

  • Risk Factors Analyses and Preventive Measures of Immersed Tunnel Engineering
    E3S Web of Conferences 23 6 , 02025 (2021) https://doi.org/10.1051/e3sconf/202123602025 ICERSD 2020 Risk factors analyses and preventive measures of immersed tunnel engineering Jiao Zhang*, Sainan Fu, Jianping Zhu, Jiancheng Wang School of Civil and Transportation Engineering, Shanghai Urban Construction Vocational College, Shanghai 200432, China Abstract. Based on the comprehensive analyses of many risk factors leading to accidents in immersed tunnel engineering, it is concluded that the risk factors leading to accidents in immersed tunnel engineering are very large and must be paid attention to in all aspects at all stages of the project. This paper classifies and identifies the risk factors in immersed tunnel engineering by investigating and visiting the relevant investigation, design and construction units of immersed tunnel, and then puts forward prevention and control measures to provide theoretical basis for the prevention of risk factors in Immersed Tunnel Engineering in the future and the risk management of the whole project. 1 Introduction 2 Visit and Research Plan The world's first railroad immersed tunnel was completed in 1901 in the United States. Since Hong Kong built 2.1 Research purpose China’s first cross-port immersed tunnel in 1972, it has By visiting and researching the construction parties of been applied more and more to our country’s cross-river various tunnel projects and experts, studying the potential, and sea-crossing projects.
