 survey on design practice in the field of soft
ground tunnelling.
2.3. To launch a working group on seismic behaviour of
tunnels.
3. Interact with other TCs and organisations concerned by
underground construction:
3.1. Proposal of an invited lecture from TC214 "Soft
soils" during the TC204 Roma symposium
3.2. To cooperate with TC104 "Physical modelling" to
extend the guidelines for comparing field or physical
model observations with numerical simulations.
3.3. To establish or maintain contact with TCs having
close interests such as TC206, TC207, TC305.
3.4. To make contact with ITA for defining fields of
possible cooperation and to investigate the possibility
of creating a common Working Group.
TC205 - SAFETY AND SERVICEABILITY
SAFETY AND SERVICEABILITY IN GEOTECHNICAL
DESIGN
Chair: Brian Simpson
TC name was changed from "Limit State Design in
Geotechnical Engineering" to Safety and serviceability in
geotechnical design
TERMS OF REFERENCE
TC205 is aware that there is already a considerable amount of
activity on issues in the scope of its remit, involving
correspondence, collaboration, meetings and conferences
between interested parties. It wishes to avoid conflict or
replication of this on-going work. TC205 therefore anticipates
collaboration with ISSMGE TC304 "Engineering Practice of
Risk Assessment and Management", ETC10 "Evaluation of the
Application of Eurocode 7", GeoSNet
and similar groupings. TC205
also notes, however, that there is a need to strengthen
interchange of ideas between various continents: America,
Asia, Australasia and Europe. Working with other interested
organisations, it will aim to achieve better communications
between the communities active in these areas. The very
existence of the TC is a useful step towards this. The following
terms of reference are provisional and subject to development
and discussion by the TC. They are listed under the four
objectives provided in Guidelines for Technical Committees.
Objective 1:
 Disseminate knowledge and practice within the TC’s subject
area to the membership of the ISSMGE:
 Set up internet forum for debate of matters related to the
TC’s subject area (agreed).
 Promote existing training information (generally web
based), webinars, etc (agreed)).
 Consider further development of webinars for global
training use (proposed for discussion).
 Undertake a "Comparison between different design practices
across the world", based on a limited number of design
examples (proposed for discussion). This could form the
basis of ISSMGE conference presentations.
Objective 2:
 To establish guidelines and technical recommendations
within the TC’s subject area:
 Set up a list of publications recommended by members of
the TC, displayed on the TC’s website (agreed).
 Members of the TC are heavily involved in development of
standards and codes of practice.
 Encourage members to provide translations into English of
codes with no existing translation, particularly as they relate
to Objective 1 Item 4 above.
Objective 3:
 Assist with technical programs of international and regional
conferences organized by the ISSMGE:
 Collaborate with and participate in
Munich, June 2011.
 Collaborate with and participate in
conference, Atlanta, June 2011.
 Collaborate with and participate in
conference, September 2012.
 Collaborate with and participate in workshop in Athens
ECSMGE, September 2011, organised jointly with ETC10,
ETC8 and ETC3.
 Organise a further conference sponsored by TC205 in 2012?
(proposed for discussion).
 Organise a workshop at Paris ICSMGE, 2013 (provisional –
to be discussed further).
Objective 4:
 Interact with industry and overlapping organizations
working in areas related to the TC’s specialist area:
 Members of the TC have lots of interaction with national
and international standards committees and frequently make
public presentations in relation these matters.
 Members to mention TC205 (even if only their own
membership of it) when making public presentations
(proposed for discussion).
TC206 - INTERACTIVE DESIGN
INTERACTIVE GEOTECHNICAL DESIGN
Chair: Ken Been
TERMS OF REFERENCE
The observational method, or interactive design, has been used
in geotechnical engineering for over half a century. The
approach is, however, only used in exceptional circumstances
and projects. A long term goal of TC206 is to gain acceptance
for the method within most geotechnical engineering design
codes.
During the previous term (2006 – 2009) a survey was carried
out of ISSMGE Members to determine the status of the
observational method and its application worldwide. Survey
participants were also asked what the ISSMGE could do to
foster use of the observational method. The respondents
indicated that the ISSMGE could usefully do the following:
 Knowledge dissemination
 Publish case histories
