Various slope masses at Guinsaugon, St. Bernard, Southern Leyte were modeled in two dimensions using the results of preliminary terrain zoning and geotechnical mapping. Local slopes are geotechnically characterized using the British Standards (ISRM 1981), the Laubscher’s Rock Mass Rating Scheme and the Hack’s Slope Stability Probability Classification Scheme. Field and laboratory findings are translated into slope design parameters. Two dimensional slope models were created to highlight the important geologic, geomorphologic, hydrogeologic and geotechnical features of the slope. For each slope model, corresponding slope design implications are summarized.

 

Using this scheme, a total of six slopes were modeled at Guinsaugon, St. Bernard, Southern Leyte. They are the slopes in lower clastics (Himayangan Clastics of the Magaupas Formation), slopes in upper clastics ( Upper Magaupas Formation), slopes in ultramafics (Imbangan-Lepanto Ultramafics)), slopes in limestone (Hinabian Limestone), slopes in clastics and colluvium, and slopes in colluvium (Magatas Mound).
