Taiwan is an island produced by the compression between two tectonic plates. This results in large variances in geological and terrain structures and frequent seismic activity. Combined with concentrated precipitation, damaged sloping regions in mountainous areas contribute to roadway breakage and endanger lives and property. For many years, disaster prevention has long been a subject of government attention. This research selects the regional corridors in Kaohsiung’s Jiasian region as the focus due to the severity of slope damages in recent years. By referencing previous publications, seven elements are chosen to evaluate the local slopes: slope gradient, slope direction, slope height, Normalized Difference Vegetation Index (NDVI), geological structure, distance from fault lines, and distance of the slope from rivers. Through the application of DEM data, satellite photos, aerial photography, and various types of GIS software to archive the data retrieved and obtain potential factors along a corridor alignment to assess the degree of destruction. Information retrieved from the slopes along corridor alignments shall consist of 17889 data points towards the establishment of the analytical model indicating slope failure potential. Slope elements are differentiated into five different categories: Low, low-medium, medium, medium-high, high potential to assist in the construction of a cliff face destruction potential analysis model similar to a neurological network. The results of the analytical model will be used towards the drafting of charts indicating slope destruction potential in efforts to provide reference towards slope destruction prevention as well as early detection systems.
