Abstract
In the night between 29th and 30th December 2010 during the filling test of the reservoir an incident occurred to the main body of the Montedoglio earth dam, located in Sansepolcro, Tuscany (Italy). Using the HST Model, this study aims to assess the behaviour of the dam core during the rapid drawdown that follows the event. The applicability of the model is verified with a finite elements method passing through different steps. At first step a simplified levee scheme and a simplified hydrograph of the reservoir level are used to determine the flow line with the solver. The results are compared with the ones estimated through the Pavlovsky method. Then the real model of the levee and the real hydrograph of the reservoir level are utilized to find a second flow line. This line is compared with the real pore pressure measurements to obtain the validation of the solver model and then with the HST predicted values. The obtained results confirm the goodness of the adopted model for the involved phenomena.File | Dimensione | Formato | |
