摘要

Plate pile mitigation for shallow landslides provides a new technique for addressing a common landslide hazard. Shallow landslides are most often a maintenance problem, but can also cause serious property damage and be life threatening. The plate pile technique provides a sound, cost-effective method for mitigating these types of slides and can be performed in a multitude of settings. To date, the methodology has been applied for mitigation against shallow residual/colluvial slides in clays overlying claystone and siltstone bedrock and both native and deep clayey fill slopes. A series of full-scale field tests have been performed to verify the applicability of the technique. In a test performed without plate piles, failure occurred following a carefully monitored irrigation procedure. In a test performed with plate piles, no failure occurred under the same test conditions. These results give credibility to the plate pile methodology. Slope stability analyses performed for the test slope conditions verify the failure conditions and provide important information regarding the increase in stability of a slope outfitted with plate piles. In general, the results show a 20% increase in the factor of safety against translative sliding failure, sufficient enough to propose this technique in numerous settings.
