Summary

With modern technical means protection of mountain areas may include: a) altering of potentially unstable and seismically dangerous slopes into safely stable and seismo-stable ones (in particular by means of directed, even nuclear explosions; b) prolongation of stages of relative stability by means of usual protection measures; c) regulation of processes, for example, by arrangement of artificially directed falls, slides and mudflows; d) prevention by means of urgent measures, not of the process itself, which is usually enormous and vast, but of its consequences, by means of by-pass channels for outlet of temporary lakes created by damming of the rivers. Of great importance is a thorough engineering-geological investigation of slopes, cycles and stages of their development, taking into consideration the scale of gravitational processes (see recommended classification), as well as the observation, prognosis and monitoring services.

Principes de la protection des pentes instables dans les montagnes a structure plissée

Résumé

La protection des régions montagneuses peut être effectuée à l’aide des techniques modernes: a) la stabilisation des versants susceptibles à l’éboulement et aux mouvements sismiques au moyen des explosions (inclusivement nucléaires) dirigées; b) prolongation des stades de stabilité relative par des mesures normales; c) la régularisation des processus, par exemple l’écartement artificiel des écroulements, glissements et coulées boueuses; d) la prévention, pas du processus propre, qui est ordinairement énorme et vaste, mais de ses conséquences, par construction d’un canal de dérivation pour vider le lac temporaire crée par le barrage de la rivière. Des recherches géotechniques profondes des versants et des cycles et stades de leur dévéloppement, en considérant l’échelle de procès de gravitation (voir la classification recommandée), sont de grande importance aussi bien que l’observation, le pronostic et la documentation des mouvements de terrain.
