Murs de contenció: de gabions, a flexió i de soterrani és un manual pràctic de projecte de murs de contenció de terres per a l'edificació. Introdueix al coneixement de les accions del sòl, n'identifica les variables i la seva influència, i determina l'empenta de les terres sobre el mur de contenció i l'equilibri del conjunt. Ensenya a escollir el tipus i a desenvolupar el projecte, des del predimensionament i les comprovacions, fins al dimensionament, l'armat, els detalls, l'amidament i el pressupost. Inclou les especificacions relatives a la posada en obra i tracta la tipologia de murs de contenció més habituals per a l'edificació, que són els que s'autosuporten per gravetat o flexió i els murs suportats de soterrani, amb una menció especial dels murs de pedra en sec, de gabions i de formigó, que s'il·lustren amb exemples concrets. És un llibre de text destinat als estudiants de grau de les escoles tècniques d'arquitectura, enginyeria i edificació, que també pot interessar els professionals.Índice1 La teoria de lempenta 1.1.
