DESCRIPTION:High Speed One (HS1) was probably the largest chalk engineerin
 g project in the UK so far this century. It was fully opened in 2007. Abou
 t 40 km of its length was built through chalk geology. There was much inno
 vation in regard to chalk earthworks for the project. With the\nrecent sta
 rt of the detailed design of High Speed Two\, it is timely to revisit the 
 design and construction of the chalk earthworks on HS1 and to consider how
  they have performed over the last decade.\nThe presentation will include 
 approaches to design\, classification\, specification and construction of 
 chalk railway embankments\; and approaches to dealing with deneholes and s
 olution features under trackbeds and in cutting side slopes\, etc.
