Research Abstract |
The performance of a high energy type rock-fence is now depending on the design method based on the cumulative and absorbable energies which have been evaluated from a manufacturer's original experimental method and its experimental value. Improvement in a simulation technique of a high energy type rock-fence was aimed in this study. It has been made clear from experiments and analyses that the rockfall characteristics, i.e., mass, configuration and velocity, etc. influence the performance of a rock-fence even if the rockfall energy is same, and that the cumulative rule is unsuitable for evaluating a performance of a high energy type rock-fence.
