En se d\u00e9gradant, le permafrost peut fragiliser la stabilit\u00e9 des terrains, ce qui menace les infrastructures qui y sont install\u00e9es. Gares de remont\u00e9es m\u00e9caniques, pyl\u00f4nes et routes d\u2019acc\u00e8s requi\u00e8rent d\u00e9sormais une attention particuli\u00e8re.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">C\u2019est dans ce contexte que le projet franco-suisse\u00a0<a href=\"https:\/\/www.interreg-francesuisse.eu\/les-projets-aides\/cryo-adapt\" target=\"_blank\" rel=\"noopener\">CRYO-ADAPT<\/a>\u00a0a vu le jour. Son objectif\u00a0: mieux comprendre les interactions entre le permafrost et les infrastructures de montagne, en combinant mesures sur le terrain, analyses en laboratoire et mod\u00e9lisation num\u00e9rique. Le consortium transfrontalier travaille directement avec les acteurs locaux pour d\u00e9velopper des outils de surveillance et tester des solutions innovantes. \u00c0 terme, il s\u2019agit d\u2019am\u00e9liorer la r\u00e9silience des infrastructures et de l\u2019activit\u00e9 touristique alpine face au changement climatique.
