Tunnelling Induced Settlements in London Clay –Effects on Buildings

With the publication of the BTS Monitoring Guide in Autumn 2011, this presentation will discuss this and the effects of Long Term Settlement in London, emphasising the effects on adjacent infrastructures, typically Network Rail and LU, at depth and on surface.

BTSYM: Tunnelling at the Olympic Park

As a part of the Olympic Delivery Authority's Learning Legacy project, presentations will be made on the PLUG (Powerlines Underground) and micro-tunnelled sewer tunnels projects at the Olympic Park.

BTS / MinSouth Joint Event - Chile Mine Rescue

A joint event with MinSouth. The presentation will describe the incident in the San Jose mine in Chile in late 2010 which saw 33 miners trapped underground for 70 days, and the subsequent successful rescue operation. It will then ask the question, are we prepared should a similar event occur in the UK?

Harding Memorial Lecture Underground Infrastructure in the UK – meeting the future needs of society

The UK is at a tipping point in economic infrastructure. We led the world in industrial development but as a result now have some of the oldest and most complex infrastructure in the world. It is increasingly in need of repair and replacement, and at the same time further infrastructure is needed to help provide growth, jobs and exports. The importance of infrastructure and the benefits of tunnelling are being recognised by our government. We need to rise to the challenge and get engaged! The lecture will look at the drivers of change in our industry, and some of the success stories of recent times. What is the shape of our industry in the future, and how do we need to change in response? What technological advances and directions of research should the country take?

AGM & Brenner Base Tunnel – Cross border planning and implementation of 64km of tunnels

The BTS AGM followed by a presentation on the 64km long Brenner Base Tunnel (BBT) deep beneath the Alps, which will connect Austria and Italy and will be the longest underground railway connection in the world. In total, the BBT system will include about 200km of tunnels, including the two main tubes, the exploratory tunnel, four lateral access tunnels and cross-passages. More than 20km have already been built. Completion is planned for 2025 and the start of operations for 2026. The project company, BBT SE, is the first bi-national European infrastructure company and construction will be financed by the European Union, Austria and Italy.

BTSYM: Influences on the global tunnel market

Influences on the Global Tunnel Market, including technology, politics and global challenges. Regions where activity is growing include the Middle East, South America and India. The market has never been as buoyant as it is now and it is postulated it will be for the foreseeable future.

London Tideway Tunnels

The Thames Water Lee Tunnel is London's deepest and largest. The 7.2m ID, 6.9km tunnel, with depths ranging from 65m to 80m is under construction in East London between the Beckton Sewage Treatment Works and the Abbey Mills Pumping Station complex. When completed in 2015, it will reduce by 40 percent the foul water discharges to the River Thames system in London. The presentation will include the design and construction of the double-lined shafts, novel aspects of the main, and many other interesting facets of this huge and exciting project.

'URUP' Ultra Rapid Under Pass (an innovation in tunnelling shield technology)

'URUP' tunnelling, developed by OBAYASHI in Japan, is an innovative shaft-less shield technology. The TBM is launched/arrives at ground level and drives under shallow cover without ground treatment. The result is significant cost savings, reduced construction time and reduced environmental impact. The critical issues in 'URUP' technology are tunnel face stability and ground movement control. Innovative methods are used that have been developed through extensive technical research and development. The new concept was proven through a verification project and adopted by several projects in Japan, which have been successfully constructed. These projects involved circular TBMs with diameters ranging from 2.1m up to 13.6m, an oval shape open-face TBM and a rectangular TBM. The presentation will describe how the URUP concept was developed, mechanisms of ground control under shallow cover and review projects where it has been successfully used.

BTSYM: Numerical modelling

This talk aims to provide practical information on the use of numerical simulation and analysis for tunnel design and construction. The focus of the talk will be on practical aspects of applying numerical analysis to tunnelling problems.

Tunnel Design Under Explosion

An explosion within an underground facility has a behaviour distinct from earthquake loading or construction blasting. When an explosion occurs in a tunnel, the peak pressure and the impulse associated with the shock front are extremely high and amplified. Because of the close-in effects of the explosion and the amplification of the blast pressures due to the reflections within the structure, the distribution of the shock loads on any one surface is non-uniform and extremely complicated. Therefore, the blast protective design requires the design engineers to understand new theory and practice in evaluation of the interactions between explosives and structures.

BTSYM: Conference, AGM and Lecture

BTS Young Members "International Tunnelling Conference for Young Engineers 2012" . The British Tunnelling Society Young Members are pleased to hold their first afternoon conference sponsored by the Institution of Civil Engineers. Please note that whilst there is no charge for the event, advance registration is necessary - to register. The conference will be followed by the AGM and then the BTSYM talk on "The Design and Construction of SCL and Segmental Lined Tunnels". The talk will aim to provide practical information on the design and construction of the differing tunnel supports, looking at design assumptions, the construction advantages and disadvantages, and the main aspects of quality control.

Fire in tunnels under construction

A fire in a tunnel under construction, or more particularly the smoke from such a fire, has the potential to lead to multiple fatalities. Fortunately, whilst there have been one or two spectacular fires in European tunnels in recent years, no one has been killed or injured. This meeting will review recent fires which occurred during tunnel construction, including at Storebelt in Denmark and on the A86 in Paris, before describing the expectations of the emergency services, and the requirements of Standards such as BS 6164 and prEN16191 (which not only require fire protection systems but are now also asking for refuge chambers).
