Surficial Failures
Surficial Failures Surficial failures frequently occur on the slopes of earthen embankments and earth-fill dams which are predominantly rainfall-induced. Unstable Slopes Unstable slopes create numerous management and engineering issues as we try to prevent slope failure. Based on the literature review and interviews conducted with selected state highway engineers , researchers identified three innovative methods of using vertical members to stabilize surficial slope failures: • 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. ...
