摘要

The linear cartographic method was developed within the scope of a study conducted on the "rockfall" risk on the national highway network in the Alpes-Maritimes department (southeastern France). This easy-to-implement method is based on a methodology first drawn up in 1978. It has since been improved and adapted for compatibility with computing resources, thanks to the capacities of the inherent analytical method. The focus of the present article is not to report on results stemming from this cartographic study, but rather to display, using the Alpes-Maritimes application as an example, the particular method derived. Linear applications other than road network itineraries can also be envisaged. This method relies on the notion of determinant factors (basic parameters able to of triggering a rockfall); such factors serve to characterize the source zone (cliff faces aligned or offset with respect to the road trajectory). After adding some minors factors (linked to block propagation area) the method provides resulting hazard on the road. These factors are determined on the field by an expert without any specified other geotechnical investigation; moreover. This factors are numerically precessed, which allows the data to be used an expressed both with analytically and synthetically table and automatic maps. The method's advantages consist of its facility and speed of implementation as well as its data-updating flexibility. The decision-making tool it provides does not however replace the in-depth and specific "rockslide" risk studies to be conducted subsequently and whose scheduling may be established from a set of rational criteria.
