„It is the first time ever that a symposium between the two ITA member nations China and Malaysia has been organized“, welcomed Dr. Teik Aun Ooi, Organizing Chairman of the SEASET 2018 (South East Asia Symposium & Exhibitions on the challenges and strategic solutions of high profile projects on Tunnels 2018) the more than 300 participants from China, Malaysia, the Southeast Asian Region and abroad in Kuala Lumpur, Malaysia. The joint symposium with a total of 18 lectures, delivered from well-known speakers, was organised by the China Civil Engineering Society (CCES) and the Institution of Engineers, Malaysia (IEM) on September 18 and 19, 2018.
The German company Schöller special machines GmbH & Co. KG (SSM) has developed a new tunnel excavator based on a Volvo excavator. This excavator is suitable, with its size of about 16–18 tonnes...
Data from clients, construction companies and designers
For almost 40 years the STUVA has carried out a survey of tunnelling in Germany. Annually collected data from clients, construction companies and designers are regularly published in consolidated form. An assignment prompted by a corresponding request from the International Tunnelling and Underground Space Association.
Since September 23, 2018 the Call for Papers for the World Tunnel Congress 2019 in Naples, Italy, is closed; the Scientific Committee reported the receipt of 730 papers. The number of scientific...
The equipment of infrastructure tunnels with absorbers for the extraction of heating or cooling energy is a consistent further development of the shallow geothermal hybrid systems in the field of ground engineering. The heat fluxes acting on a tunnel geothermal plant result from a complex interaction of the climatic conditions at the surface and inside the tunnel, the subsoil conditions and the operation of the geothermal plant. A prediction of possible heat extraction rates is thus only possible on the basis of transient simulations. In the article from tunnel issue 6/2018, a simulation application for the investigation of tunnel geothermal plants developed at the Institute of Geotechnical Engineering of the University of Stuttgart is presented, and the results of parameter studies regarding the heat extraction performance from a shallow urban transit tunnel are discussed.
