Dimensionamento delle gradonate e loro effetto sulla stabilità dei versanti

Abstract

Nell’ambito dell’ingegneria naturalistica le gradonate, realizzate con talee o piantine radicate, costituiscono interventi maggiormente diffusi nella sistemazione di frane superficiali o nella realizzazione di scarpate ad elevata pendenza come nel caso della realizzazione di strade agro-silvo-pastorali. L’effetto di queste opere è duplice, nell’immediato viene fornito un rinforzo ad opera delle talee o dei fusti delle piantine, successivamente si ha un ulteriore rinforzo dovuto alla presenza delle radici avventizie. Nonostante la grande diffusione di queste opere, gli schemi di calcolo in grado di quantificarne l’effetto di rinforzo e di guidare la scelta dei parametri progettuali sono ancora scarsi. Nel presente lavoro viene illustrata una metodologia di calcolo basata sul principio dell’equilibrio limite del pendio indefinito al fine di valutare il fattore di sicurezza di versanti rinforzati con talee. Nel caso specifico viene considerato il salice rosso (Salix purpurea L.) per il quale sono state condotte sperimentazioni per valutare i parametri che regolano la resistenza allo sfilamento delle tale ed il rinforzo esercitato dalle radici avventizie.
