Risk assessment and quantification of slope condition based upon site inspection surveys

Railtrack plc are responsible for the maintenance of over 32,000 km of track. A significant proportion of this is carried on embankment or passes through cutting. These earthworks require a structured maintenance programme to ensure their ongoing good performance. Allott & Lomax were commissioned by Railtrack plc's Midland and Southern Zone to undertake a slope condition survey of 350 route miles of railway line. The objective of the study was to create a register of all embankments and cuttings greater than three metres and identify all sites of existing or suspected instability. The data would be utilised by Railtrack plc in setting minimum slope maintenance requirements. This paper describes the development of a data management system, the risk assessment philosophy adopted and improvements that could be incorporated into the Railtrack plc specified slope condition scoring system to improve its assessment potential.
