Slope stabilisation works at Lyme Regis were completed in 2015. Part of the scheme included a row of piles to protect land lying above a large mobile soil mass, which was not to be stabilised. In turn these were secured at their heads using anchors; a passive geotechnical structure.
Earth Science Partnership Technical Director and RoGEP Advisor, Dr Mark O’Neill, was involved with the geotechnical design of this scheme. Mark noted on a recent visit to Lyme Regis how these piles are now beginning to work; the soils in front of the piles have moved over the winter period and the upper portion of the piles have now been revealed; it is only as this movement occurs that they begin to act as a retaining structure.
This is how part of the project appears at present with the soil mass mobilising away from the piled structures:
