TC204 Underground Construction

Geotechnical Aspects of Underground Construction in Soft Ground

Host Member Society: UK and Italy

Short name: Underground Construction (TC204)

Technical Committee 204 (TC204) "Geotechnical Aspects of Underground Construction in Soft Ground", was first established in 1989 as TC28 and is currently in its seventh term. It has completed one term with Prof Keiichi Fujita as Chairman (1989-1995), two with Prof Robert Mair (1995-2005), another one with Prof Richard Kastner (2006-2011), and two with Prof. Adam Bezuijen (2012-2022). The current Chair is Prof Giulia Viggiani.  

The main topics addressed by TC204 concern the geotechnical aspects of the analysis, design, monitoring, construction, and maintenance of deep excavations, tunnels, and large underground structures in the urban environment, with particular emphasis on the development, effects, and control of ground movements, their interaction with existing structures, mitigation measures, and risk management.

TC204 has organised ten International Symposia (IS); the first was held in New Delhi in 1994 and nine more were held in London (1996), Tokyo (1999), Toulouse (2002), Amsterdam (2005), Shanghai (2008), Rome (2011), Seoul (2014), Sao Paulo (2017), and Cambridge (2022).

To recognise his inspirational leadership and enormous technical and organisational contributions in establishing TC204, an Honorary "Keiichi Fujita Lecture" was introduced in 2011, to be delivered every three years at TC204 International Symposia. Distinguished Fujita Lecturers have included Dr Hugh D. St John (2014), Prof Hirokazu Akagi, and Prof Robert J. Mair (2022). Prof Adam Bezuijen will deliver the fourth "Keiichi Fujita Lecture" at IS-Macau 2024.

IS-Cambridge Posponed until June 2022

Unfortunately, due to the continuing global COVID-19 emergency meaning that large-gatherings should be avoided to prevent further spread of the virus, the LOC have made the difficult decision to postpone the conference again until June 2022 (27th to 29th June 2022).

The main topics addressed by TC204 concern the geotechnical aspects of the analysis, design, construction and maintenance of deep excavations, tunnels and large underground structures, with particular emphasis on the development, effects and control of ground movements, their interaction with existing structures, mitigation measures and risk management. In this field the objectives for the period 2013-2017 are as follows.

- To deliver the 9th International Conference on "Geotechnical Aspects of Underground Construction in Soft Ground" in Seoul, 25-27 August, 2014, which was achieved and was a success.

- To prepare the organisation of the 10th International Conference on "Geotechnical Aspects of Underground Construction in Soft Ground" in 2017 in Brazil.

- To promote a session or a workshop during the next ICSMGE, Seoul 2017.

- Develop a database of all proceedings of the previous symposia, unless this interferes with copyrights. At the moment there is permission for the first 6th symposia.

- To actively encourage the preparation of papers from TC204 members to be published in refereed journals and in particular for the ISSMGE International Journal of Geo-Engineering Case histories.

- Proposal for the 2nd Fujita lecture 2017 to be held at the TC204 symposium in Brazil. This will be Prof. Hirokazu Akagi from Japan. Interaction with other TCs concerned by underground construction:

- To cooperate with TC104 "Physical modelling" to extend the guidelines for comparing field or physical model observations with numerical simulations.

- To establish or maintain contact with TCs having close interests such as TC206, TC207, TC305 and TC203.

- To edit a list of codes and guidelines existing worldwide in the field of geotechnical aspects of tunnelling.

- To link in with continuing work on the seismic behaviour of tunnels. Interaction with other TCs and organisations concerned by underground construction:

- To cooperate with TC104 "Physical modelling" to extend the guidelines for comparing field or physical model observations with numerical simulations.

- To establish or maintain contact with TCs having close interests such as TC206, TC207, TC305 and TC203.

- To organise regional workshops on the occasion of large or challenging projects.

- To encourage the active participation (papers, lectures, workshops) of TC204 members at regional conferences. For example, 13th international conference "Underground Construction Prague 2016" will take place in Prague, Czech Republic, May 23-25 2016.

- To strengthen links with the ITA and investigate future cooperation.
