PRESSURES EXERTED BY FRACTURED ROCK MASS ON RETAINING WALLS: NON ASSOCIATIVE AND NON LINEAR FAILURE CRITERION
We study the pressure of a natural medium with non-linear and non-associative failure criterion on a vertical wall. This is particularly useful for analysing rock media which are extensively fractured or weathered. The application of the Hoek and Brown (1980) failure criterion is extended to the case of walls retaining with heavily fractured rock masses or volcanic materials such as pyroclasts slightly cemented, as well as to rock fill or other materials with non-linear resistance laws. In this case, specific mention is made to materials with a Hoek and Brown (1980) failure criterion and a constant dilatancy angle of 0o and 4o respectively, according to Hoek and Brown (1997) recommendations.
