BTS / MinSouth Joint Event - The Ingula Pumped Storage Scheme

The Ingula Pumped Storage Scheme is currently the largest tunnelling project in South Africa. The location is 400km south-west of Johannesburg and 80km north-east of Lesotho. There are over 12km of tunnels up to 9.4m diameter, 4 shafts (up to 20m dia x 190m deep), 2 large caverns, requiring substantial support. The geology is primarily a relatively weak sedimentary rock, with dolerite dykes and sills.

High Speed Railway Tunnels in Spain

With the opening of the new Levante line, the Spanish High Speed Railway network has become the longest in the world. HSR lines with their demanding alignments require the design and construction of an unusually high number of tunnels, some of which are amongst the longest and most important in the world. This presentation provides information of three good examples of the tunnels recently built in Spain: Guadarrama tunnel, Pajares tunnel and finally Atocha-Chamartín tunnel. This is an evening BTS Presentation being held at the "BTS Underground Conference 2011" on 29th to 30th June 2011. It is a two-day conference being held in the Earls Court Exhibition Centre.

BTS / BGA joint meeting: What do we want from a GBR?

Geotechnical baseline reports or ground reference conditions are increasingly being used in tunnelling contracts in the UK to allocate ground risk and ensure compliance with current industry best practice and perhaps more critically, insurers recommendations. What do clients, designers and contractors expect from a GBR and how do they envisage the document will be used before, during and after construction? The aim of the meeting is to discuss the current status of the use of these documents and to learn from the practical experiences of others. Following short presentations, an active debate is envisaged and the audience will be encouraged to participate and share their own experiences.
