The British Geotechnical Association (BGA) is the principal
association for geotechnical engineers in the United Kingdom.
The Organising Committee of the Chalk 2018 Conference is pleased to announce the detailed conference programme. The oral sessions are described below. In addition, there is a Technical Exhibition and poster displays.
Day 1 of the conference on Monday 17th September 2018 includes two Keynote Lectures and 26 oral presentations in two parallel streams.
The keynotes will be Professor Rory Mortimore on ‘Developing Ground Models for Chalk Engineering: Links across the Disciplines’ and Dr Clive Edmonds on ‘Review of Collapse Events on Chalk since 2000 and the Opportunities for Improved Engineering Practice’.
Parallel sessions will cover Case Histories, Earthworks, Foundations & Piling and Geological Hazards. Highlights include presentations of the Andrew Lord Memorial Papers on HS1 earthworks, case histories from Crossrail, Tideway and the Lee Tunnel, and discussion of cliff stability problems in chalk.
Day 1 will finish with conference drinks and a buffet reception.
Day 2 of the conference on Tuesday 18th September 2018 includes one Keynote Lecture and 32 oral presentations in two parallel streams.
The keynote will be Professor Richard Jardine on ‘Behaviour of Piles Driven in Chalk’
Parallel sessions will cover site investigation, in-situ and laboratory testing, future engineering issues, offshore engineering, tunnelling and water & the environment Highlights include presentations on the mechanical and hydraulic properties of chalk, discussion of rota-sonic drilling in chalk and a comparison of EPB and slurry TBMs for tunnelling in chalk.
The main conference will finish at the end of Day 2.
After the end of the main conference Technical Visits will be held, for those delegates who selected this option (numbers are limited), on Wednesday 19 September 2018.
Two technical visits are available:
Excursion to the chalk exposures of the Sussex Coast
This trip will be led by Professor Rory Mortimore.
Coaches will leave Imperial College at approximately 08:00 and will return by approximately 18:00.
Lunch will be provided.
Starting at the West end of Brighton Marina we will discuss the local engineering/geology: Black Rock Marina; Brighton & Hove Stormwater Tunnel; Brighton to Peacehaven new sewer tunnel; coastal engineering and cliff instability. The group will be introduced to some of the issues related to cliff retreat, the methods of monitoring and the different types of remedial engineering. Working along the undercliff walk behind Brighton Marina for approximately 1 kilometre. Upon reaching the East end of the Marina the group will stop for lunch.
In the afternoon the group will travel to Saldean where Prof Mortimore will introduce the group to Chalk geology and some key marker beds; dry valley and Quaternary processes.
This trip will be led by Dr Clive Edmonds.
Coaches will leave Imperial College at approximately 08:30 and will return by approximately 19:00.
Lunch will be provided.
This will involve a walk around Coley area, Reading in the morning to view evidence of past quarrying/mining and crown hole collapses. This will be followed by a visit to the Emmer Green chalk mine visit near Reading (this in an underground visit and requires climbing of ladders).
Delegates who have booked a Technical Visit will be contacted by email to request their preference for which visit to attend. Note that places are limited and first preferences will be allocated on a first come, first served basis.
