Cette th\u00e8se intitul\u00e9e : \u00ab Mod\u00e9lisation optimale de l\u2019analyse de d\u00e9formation g\u00e9om\u00e9trique avec technique de fusion d\u2019observations g\u00e9od\u00e9siques et g\u00e9otechniques \u00bb<\/strong>, met en \u00e9vidence les efforts visant \u00e0 am\u00e9liorer les syst\u00e8mes de surveillance des ouvrages sensibles, notamment les barrages.<\/p>\n

R\u00e9sum\u00e9\u00a0: <\/strong><\/p>\n

La gestion de la s\u00e9curit\u00e9 des barrages est mise en place, de mani\u00e8re \u00e0 ce qu\u2019elle fournisse en premier lieu un \u00e9tat op\u00e9rationnel de surveillance en temps r\u00e9el et qu\u2019elle permette d\u2019en tirer les solutions efficaces pour parer aux faiblesses existantes ou \u00e0 venir sur le comportement de l\u2019ouvrage. Les concepts modernes de surveillance de l\u2019\u00e9tat des structures (SHM), tels que le Syst\u00e8me d\u2019Analyse Int\u00e9gr\u00e9\/SAI, la Fusion de Donn\u00e9es Multi-capteurs (FDM), et l\u2019Intelligence Artificielle (IA) sont ax\u00e9s sur la surveillance syst\u00e9matique de l\u2019\u00e9tat des structures afin de garantir leur s\u00e9curit\u00e9, leur fiabilit\u00e9 et leur durabilit\u00e9.<\/p>\n

Dans ce contexte, cette th\u00e8se vise l\u2019estimation des tassements de surface du barrage en enrochement \u00e0 noyau central en argile de KERRADA (Mostaganem, Alg\u00e9rie), en adoptant une approche multidisciplinaire de fusion de donn\u00e9es multi-capteurs (FDM) combinant les mesures g\u00e9otechniques (tassom\u00e8tres) et g\u00e9od\u00e9siques (nivellement). La m\u00e9thodologie repose sur une fusion \u00e0 deux niveaux : une premi\u00e8re estimation locale des tassements au niveau des capteurs, suivie de leur g\u00e9n\u00e9ralisation par interpolation au moyen de r\u00e9seaux de neurones \u00e0 Fonctions de Base Radiale (FBRN), selon trois algorithmes (Newrb, Newrbe et Rgnn). Cette d\u00e9marche permet de g\u00e9n\u00e9rer les tassements sur toute la surface du barrage, m\u00eame en cas d\u2019insuffisance spatio-temporelle d\u2019observations. La validation des r\u00e9sultats, notamment par l\u2019extraction de l\u2019Indice de Tassement (IT), a confirm\u00e9 un comportement normal de l\u2019ouvrage, ouvrant ainsi des perspectives d\u2019optimisation du mod\u00e8le par l\u2019int\u00e9gration d\u2019algorithmes d\u2019IA plus performants.<\/p>\n
