Surficial failuresSurficial failures occur frequently on the slopes of earthen embankments and earth fill dams which are predominantly rainfall induced.
• Installing small structural members by conventional methods.
• Installing launched soil nails.
• Installing earth anchoring systems.
Investigators also determined that some of these methods are more cost-effective than conventional repair methods.
Slope failure in embankments during and after construction is sometimes associated with the interface between the natural ground and the fill material. Pore water pressures and seepage within the embankment and natural ground may exacerbate slope failures.
