A long-term record of water content and pore water pressure in a vegetated clay highway cut slope
A long-term record of water content and pore water pressure in a vegetated clay highway cut slope
The major highway network in the UK was developed from the 1960’s and the earthworks are generally well engineered. However, as many of the earthworks get older, slope failures are becoming more common, with some posing a threat to the safety of transport operations. Field measurements of soil water content and pore water pressure changes within the surface zone of a highway cut slope in London Clay at Newbury, Berkshire, UK have been carried out continuously since 2003. This paper describes and gives examples of the long-term field measurements from the site at Newbury, and details a number of significant findings from the observations from the site. The paper explains how these have been used to calibrate appropriate models of seasonal cycles of pore water pressure and slope deterioration.

Abstract
The major highway network in the UK was developed from the 1960’s and the earthworks are generally well engineered. However, as many of the earthworks get older, slope failures are becoming more common, with some posing a threat to the safety of transport operations. Field measurements of soil water content and pore water pressure changes within the surface zone of a highway cut slope in London Clay at Newbury, Berkshire, UK have been carried out continuously since 2003. This paper describes and gives examples of the long-term field measurements from the site at Newbury, and details a number of significant findings from the observations from the site. The paper explains how these have been used to calibrate appropriate models of seasonal cycles of pore water pressure and slope deterioration.
